Johan Hovold 998912346c media: ov519: add missing endpoint sanity checks
Make sure to check that we have at least one endpoint before accessing
the endpoint array to avoid dereferencing a NULL-pointer on stream
start.

Note that these sanity checks are not redundant as the driver is mixing
looking up altsettings by index and by number, which need not coincide.

Dongchun Zhu f1a64f5666 media: i2c: ov5695: Fix power on and off sequences
From the measured hardware signal, OV5695 reset pin goes high for a
short period of time during boot-up. From the sensor specification, the
reset pin is active low and the DT binding defines the pin as active
low, which means that the values set by the driver are inverted and thus
the value requested in probe ends up high.

Fix it by changing probe to request the reset GPIO initialized to high,
which makes the initial state of the physical signal low.

In addition, DOVDD rising must occur before DVDD rising from spec., but
regulator_bulk_enable() API enables all the regulators asynchronously.
Use an explicit loops of regulator_enable() instead.

For power off sequence, it is required that DVDD falls first. Given the
bulk API does not give any guarantee about the order of regulators,
change the driver to use regulator_disable() instead.

The sensor also requires a delay between reset high and first I2C
transaction, which was assumed to be 8192 XVCLK cycles, but 1ms is
recommended by the vendor. Fix this as well.

Lad Prabhakar ca45448a56 media: i2c: imx219: Fix power sequence
When supporting Rpi Camera v2 Module on the RZ/G2E, found the driver had
some issues with rcar mipi-csi driver. The sensor never entered into LP-11
state.

The powerup sequence in the datasheet[1] shows the sensor entering into
LP-11 in streaming mode, so to fix this issue transitions are performed
from "streaming -> standby" in the probe() after power up.

With this commit the sensor is able to enter LP-11 mode during power up,
as expected by some CSI-2 controllers.

The debug output for tvp5150_selmux() isn't really intuitive. Register
values are printed decimal formatted and the input/output driver states
are printed as enum. Even more the "normal" output enum mapps to zero so
a active output will printing output=0 and a inactive output=1.

Change this by brinting the register values hex formatted and the states

Marco Felsch baf1782194 media: tvp5150: add support to limit sdtv standards
The tvp5150 accepts NTSC(M,J,4.43), PAL (B,D,G,H,I,M,N) and SECAM video
data and is able to auto-detect the input signal. The auto-detection
does not work if the connector does not receive an input signal and the
tvp5150 might not be configured correctly. This misconfiguration leads
into wrong decoded video streams if the tvp5150 gets powered on before
the video signal is present.

Limit the supported sdtv standards according to the actual selected
connector to avoid a misconfiguration.

Marco Felsch 0556f1d580 media: tvp5150: add input source selection of_graph support
This patch adds the of_graph support to describe the tvp input connections.
Physical the TVP5150 has three ports: AIP1A, AIP1B and YOUT. As result
of discussion [1],[2] the device-tree maps these ports 1:1. Look at the
Documentation for more information. Since the TVP5150 is a converter/bridge
the device-tree must contain at least 1-input and 1-output port. The
mc-connectors and mc-links are only created if the device-tree contains the
corresponding connector nodes. If more than one connector is available the
media_entity_operations.link_setup() callback ensures that only one
connector is active.

Javier Martinez Canillas a080a92a6f media: partial revert of "[media] tvp5150: add HW input connectors support"
Commit f7b4b54e63 ("[media] tvp5150: add HW input connectors support")
added input signals support for the tvp5150, but the approach was found
to be incorrect so the corresponding DT binding commit 82c2ffeb21
("[media] tvp5150: document input connectors DT bindings") was reverted.

This left the driver with an undocumented (and wrong) DT parsing logic,
so lets get rid of this code as well until the input connectors support
is implemented properly.

It's a partial revert due other patches added on top of mentioned commit
not allowing the commit to be reverted cleanly anymore. But all the code
related to the DT parsing logic and input entities creation are removed.

After the switch to use v4l2_async_notifier_add_subdev() and
v4l2_async_notifier_cleanup(), unloading the ti_cal module would cause a
kernel oops.

This was root cause to the fact that v4l2_async_notifier_cleanup() tries
to kfree the asd pointer passed into v4l2_async_notifier_add_subdev().

In our case the asd reference was from a statically allocated struct.
So in effect v4l2_async_notifier_cleanup() was trying to free a pointer
that was not kalloc.

So here we switch to using a kzalloc struct instead of a static one.
To achieve this we re-order some of the calls to prevent asd allocation
from leaking.

	wait_queue_head_t wq;
};

fw_ver starts at 4 byte boundary. If system enables
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS, strscpy() will do
read_word_at_a_time(), which tries to read 8-byte: *(unsigned long *)addr

vpu_init_ipi_handler() calls strscpy(), which would lead to crash.

vpu_init_ipi_handler() and several other handlers (eg.
vpu_dec_ipi_handler) only do read access to this data, so they can be
const, and we can use memcpy_fromio() to copy the buf to another non iomem

clock settings and firmware, along with differences in register settings.

Changes were reverse engineered using an instrumented downstream GPLv2
driver to compare i2c traffic and clocking. The mclk functions are from
the downstream GPLv2 driver.

Sean Young e6c6d7d4a1 media: rc: make scancodes 64 bit
There are many protocols that encode more than 32 bit. We want 64 bit
support so that BPF IR decoders can decode more than 32 bit. None of
the existing kernel IR decoders/encoders support 64 bit, for now.

The MSC_SCAN event can only contain 32 bit scancodes, so we only generate
MSC_SCAN events if the scancode fits into 32 bits. The full 64 bit
scancode can be read from the lirc chardev.

Neil Armstrong 2b48e11386 media: v4l2-mem2mem: handle draining, stopped and next-buf-is-last states
Since the draining and stop phase of the HW decoder mem2mem bahaviour is
now clearly defined, we can move handling of the following states to the
common v4l2-mem2mem core code:
- draining
- stopped
- next-buf-is-last

By introducing the following v4l2-mem2mem APIs:
- v4l2_m2m_encoder_cmd/v4l2_m2m_ioctl_encoder_cmd to handle start/stop command
- v4l2_m2m_decoder_cmd/v4l2_m2m_ioctl_decoder_cmd to handle start/stop command
- v4l2_m2m_update_start_streaming_state to update state on start of streaming
of the de/encoder queue
- v4l2_m2m_update_stop_streaming_state to update state on stop of streaming
of the de/encoder queue
- v4l2_m2m_last_buffer_done to make the current dest buffer as the last one

And inline helpers:
- v4l2_m2m_mark_stopped to mark the de/encoding process as stopped
- v4l2_m2m_clear_state to clear the de/encoding state
- v4l2_m2m_dst_buf_is_last to detect the current dequeued dst_buf is the last
- v4l2_m2m_has_stopped to detect the de/encoding stopped state
- v4l2_m2m_is_last_draining_src_buf to detect the current source buffer should
 be the last processing before stopping the de/encoding process

The special next-buf-is-last when min_buffers != 1 case is also handled
in v4l2_m2m_qbuf() by reusing the other introduced APIs.

This state management has been stolen from the vicodec implementation,
and is no-op for drivers not calling the v4l2_m2m_encoder_cmd or
v4l2_m2m_decoder_cmd and v4l2_m2m_update_start/stop_streaming_state.

The vicodec will be the first one to be converted as an example.

Hans Verkuil 2fae4d6aab media: v4l2-ctrls: v4l2_ctrl_request_complete() should always set ref->req
When the request is completed, all controls are copied to the request object.
However, when VIDIOC_G_EXT_CTRLS attempts to read control values from the
request it will read the current value instead for any control reference that
has a NULL ref->req pointer. But that's wrong: after completing the request
*all* controls should have a non-NULL ref->req pointer since they are after
all copied to the request.

So set ref->req if it wasn't set already.

Sergiu Cuciurean 204c7b3c06 media: spi: gs1662: Use new structure for SPI transfer delays
In a recent change to the SPI subsystem [1], a new `delay` struct was added
to replace the `delay_usecs`. This change replaces the current
`delay_usecs` with `delay` for this driver.

The `spi_transfer_delay_exec()` function [in the SPI framework] makes sure
that both `delay_usecs` & `delay` are used (in this order to preserve
backwards compatibility).

The entity variable was being initialized in the wrong place, before the
parameters have been checked.
To solve this, completely removed the entity variable and replaced it
with the initialization value : &sd->entity.
This will avoid dereferencing 'sd' pointer before it's being checked if
it's NULL.

Dafna Hirschfeld 403265137f media: vimc: use-after-free fix - release vimc in the v4l_device release
A use-after-free bug occures when unbinding the device while it streams.
The 'struct vimc_ent_device' allocated for the 'Sensor A' is freed
when calling the sensor's 'rm' callback but the freed pointer is
later accessed in the function 'vimc_streamer_pipeline_terminate'.
To fix this bug, move the release callback of the vimc entities
and vimc_device to the release callback of v4l2_device.
The .rm callback of vimc_ent_config is replaced by two callbacks:

.unregister - this is called upon removing the device and
it unregisters the entity. This is an optional callback since
subdevices don't need to implement it because they are already
unregistered in v4l2_device_unregister.

.release - this is called from the release callback of v4l2_device
and it frees the entity.

This ensures that the entities will be released when the last fh
of any of the devices is closed.

The commands that cause the crash and the KASAN report:

media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]'
media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]'

Dafna Hirschfeld 4babf057c1 media: vimc: allocate vimc_device dynamically
In future patch, the release of the device will move
to the release callback of v4l2_device. Therefore the
device will be released only when the last fh will be
closed. Dynamic allocation will then be needed since
when the device is unbounded and then bounded again,
it might be that the probe callback will run before
the release of the last device is finished. In that
case both operations will run on the same memory
concurrently and cause memory corruption.
This patch also removes the pdev field of
vimc_device since it is not needed anymore.

AST2500 except VR084 register which provides more precise JPEG
size read back. This commit adds support for the difference and
adds 'aspeed,ast2600-video-engine' compatible OF string.

Josef reported that his old-and-good Plextor ConvertX M402U video
converter spews lots of WARNINGs on the recent kernels, and it turned
out that the device uses a bulk endpoint for interrupt handling just
like 2250 board.

For fixing it, generalize the check with the proper verification of
the endpoint instead of hard-coded board type check.

Ezequiel Garcia 8fd390b89c media: Split v4l2_pipeline_pm_use into v4l2_pipeline_pm_{get, put}
Currently, v4l2_pipeline_pm_use() prototype is:

  int v4l2_pipeline_pm_use(struct media_entity *entity, int use)

Where the 'use' argument shall only be set to '1' for enable/power-on,
or to '0' for disable/power-off. The integer return is specified
as only meaningful when 'use' is set to '1'.

Let's enforce this semantic by splitting the function in two:
v4l2_pipeline_pm_get and v4l2_pipeline_pm_put. This is done
for several reasons.

It makes the API easier to use (or harder to misuse).
It removes the constraint on the values the 'use' argument
shall take. Also, it removes the need to constraint
the return value, by making v4l2_pipeline_pm_put void return.

And last, it's more consistent with other kernel APIs, such
as the runtime pm APIs, which makes the code more symmetric.

The driver is deprecated and scheduled for removal by the end

hardware, and it produces a continuous stream of syzbot errors due
to poor code.

In order to prevent removal the following actions would have to
be taken:

- clean up the code
- convert to the vb2 framework
- fix the disconnect and free-on-last-user handling (i.e., add
  a release callback for struct v4l2_device and rework the code
  to use that correctly).

Gustavo A. R. Silva c8efa2c826 media: rc: iguanair: Replace zero-length array with flexible-array member
The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

This issue was found with the help of Coccinelle.

Hans Verkuil 238e4a5baa media: rename VFL_TYPE_GRABBER to _VIDEO
We currently have the following devnode types:

enum vfl_devnode_type {
        VFL_TYPE_GRABBER        = 0,
        VFL_TYPE_VBI,
        VFL_TYPE_RADIO,
        VFL_TYPE_SUBDEV,
        VFL_TYPE_SDR,
        VFL_TYPE_TOUCH,
        VFL_TYPE_MAX /* Shall be the last one */
};

They all make sense, except for the first: GRABBER really refers to /dev/videoX
devices, which can be capture, output or m2m, so 'grabber' doesn't even refer to
their function anymore.

Let's call a spade a spade and rename this to VFL_TYPE_VIDEO.

Eugen Hristev 4e52889f48 media: atmel: atmel-isc-base: expose white balance as v4l2 controls
This exposes the white balance configuration of the ISC as v4l2 controls
into userspace.
There are 8 controls available:
4 gain controls, sliders, for each of the BAYER components: R, B, GR, GB.
These gains are multipliers for each component, in format unsigned 0:4:9
with a default value of 512 (1.0 multiplier).
4 offset controls, sliders, for each of the BAYER components: R, B, GR, GB.
These offsets are added/substracted from each component, in format signed
1:12:0 with a default value of 0 (+/- 0)

To expose this to userspace, added 8 custom controls, in an auto cluster.

To summarize the functionality:
The auto cluster switch is the auto white balance control, and it works
like this:
AWB == 1: autowhitebalance is on, the do_white_balance button is inactive,
the gains/offsets are inactive, but volatile and readable.
Thus, the results of the whitebalance algorithm are available to userspace
to read at any time.
AWB == 0: autowhitebalance is off, cluster is in manual mode, user can
configure the gain/offsets directly. More than that, if the
do_white_balance button is pressed, the driver will perform
one-time-adjustment, (preferably with color checker card) and the userspace
can read again the new values.

With this feature, the userspace can save the coefficients and reinstall
them for example after reboot or reprobing the driver.

Only ARGB32-type pixelformat were assumed to have 4 components, which is
wrong since RGB32-type pixelformats may have an alpha channel, so they

The XRGB32-type pixelformats really have only 3 color components, but this
complicated matters since that creates strides that are sometimes width * 3
and sometimes width * 4, and in fact this can result in buffer overflows.

Keep things simple by just always processing all 4 color components.

In the future we might want to optimize this again for the XRGB32-type
pixelformats, but for now keep it simple and robust.

John Hubbard f1f6a7dd9b mm, tree-wide: rename put_user_page*() to unpin_user_page*()
In order to provide a clearer, more symmetric API for pinning and
unpinning DMA pages.  This way, pin_user_pages*() calls match up with
unpin_user_pages*() calls, and the API is a lot closer to being
self-explanatory.

John Hubbard 1f815afcfc media/v4l2-core: pin_user_pages (FOLL_PIN) and put_user_page() conversion
1. Change v4l2 from get_user_pages() to pin_user_pages().

2. Because all FOLL_PIN-acquired pages must be released via
   put_user_page(), also convert the put_page() call over to
   put_user_pages_dirty_lock().

John Hubbard 3c7470b6f6 media/v4l2-core: set pages dirty upon releasing DMA buffers
After DMA is complete, and the device and CPU caches are synchronized,
it's still required to mark the CPU pages as dirty, if the data was
coming from the device.  However, this driver was just issuing a bare
put_page() call, without any set_page_dirty*() call.

Fix the problem, by calling set_page_dirty_lock() if the CPU pages were
potentially receiving data from the device.

Linus Torvalds 634cd4b6af Merge branch 'efi-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI updates from Ingo Molnar:
 "The main changes in this cycle were:

   - Cleanup of the GOP [graphics output] handling code in the EFI stub

   - Complete refactoring of the mixed mode handling in the x86 EFI stub

   - Overhaul of the x86 EFI boot/runtime code

   - Increase robustness for mixed mode code

   - Add the ability to disable DMA at the root port level in the EFI
     stub

   - Get rid of RWX mappings in the EFI memory map and page tables,
     where possible

   - Move the support code for the old EFI memory mapping style into its
     only user, the SGI UV1+ support code.

   - plus misc fixes, updates, smaller cleanups.

  ... and due to interactions with the RWX changes, another round of PAT
  cleanups make a guest appearance via the EFI tree - with no side
  effects intended"

Looking into the output from usbmon, the interesting part is the
following data packet:

  ffff880069c63e00 30710169 C Ci:1:002:0 0 143 = 09028f00 01030080
  00090403 00000e01 00000924 03000103 7c003328 010204db

If we drop the lead configuration and interface descriptors, we're left
with an output terminal descriptor describing a generic display:

  /* Output terminal descriptor */
  buf[0]	09
  buf[1]	24
  buf[2]	03	/* UVC_VC_OUTPUT_TERMINAL */
  buf[3]	00	/* ID */
  buf[4]	01	/* type == 0x0301 (UVC_OTT_DISPLAY) */
  buf[5]	03
  buf[6]	7c
  buf[7]	00	/* source ID refers to self! */
  buf[8]	33

The problem with this descriptor is that it is self-referential: the
source ID of 0 matches itself! This causes the 'struct uvc_entity'
representing the display to be added to its chain list twice during
'uvc_scan_chain()': once via 'uvc_scan_chain_entity()' when it is
processed directly from the 'dev->entities' list and then again
immediately afterwards when trying to follow the source ID in
'uvc_scan_chain_forward()'

Add a check before adding an entity to a chain list to ensure that the
entity is not already part of a chain.

Alexandre Courbot baf98b0ad3 media: mtk-vcodec: use v4l2_m2m_buffer where appropriate
Despite using M2M in both the decoder and encoder, this driver used
vb2_v4l2_buffer as its base buffer structure, and placed a list_head
right after the buffer declaration in order to match the layout of a
v4l2_m2m_buffer. This is very dangerous as it means the driver will
break should the layout of v4l2_m2m_buffer change.

Fix this by directly using v4l2_m2m_buffer and updating the sites that
accessed the buffer accordingly.

i2c_new_scanned_device(). Make use of the new ERRPTR if suitable. Change
the legacy function to simply return void because the retval was never
used anywhere.

Aditya Pakki 1ec4c6efe2 media: saa7146: Avoid using BUG_ON as an assertion
In video_begin and video_end, saa7146_format_by_fourcc can return
NULL and is checked via BUG_ON. However, by returning the error
to the callers upstream, we can avoid the crash and handle it via
recovery code.

Arnd Bergmann 1dc8b65c94 media: v4l2-core: only zero-out ioctl-read buffers
The memset() got moved out of the check for _IOC_NONE, so passing a
made-up command number with a size but no direction would allow clearing
data on user-provided pointers.

Move video_get_user() back into the _IOC_NONE check where it belongs.

Shawn Guo e4b9b6454d media: rc: ir-hix5hd2: add hi3796cv300-ir support
The IR device on Hi3796CV300 SoC is mostly same as hix5hd2, except the
following two things.

 - IR_CLK offset is 0x60 instead of 0x48.
 - It needs to set an extra bit in IR_ENABLE register to enable IR.

The following changes are made to deal with them.

 - Define a SoC specific data to accommodate IR_CLK offset and the flag
   telling requirement of extra enable bit.
 - Create function hix5hd2_ir_enable() to handle IR enabling. The original
   hix5hd2_ir_enable() is all about managing IR clock, so gets renamed
   to hix5hd2_ir_clk_enable().
 - Device table hix5hd2_ir_table[] gets moved forward, as it's being
   used by hix5hd2_ir_probe() now.

Johann Friedrichs 000e675182 media: dvb-core: Fix receiving invalid EIT-sections
Resetting buf without resetting pusi_seen at a channel-switch can lead
to copying the rest of a section to the start of buf, but treating it as
a complete section, when the next pusi arrives.
EIT-sections starting without valid header were randomly received during
an EIT-scan on a transponder.

This header file now only includes the cros_ec_dev struct, however, is the
'include/linux/platform_data/cros_ec_proto.h' who contains the definition of
all the Chrome OS EC related structs. There is no reason to have a
separate include for this struct so move to the place where other
structs are defined. That way, we can remove the include itself, but also
simplify the common pattern

    #include <linux/mfd/cros_ec.h>
    #include <linux/platform_data/cros_ec_proto.h>

for a single include

    #include <linux/platform_data/cros_ec_proto.h>

The changes to remove the cros_ec.h include were generated with the
following shell script:

    git grep -l "<linux/mfd/cros_ec.h>" | xargs sed -i '/<linux\/mfd\/cros_ec.h>/d'

Chen-Yu Tsai 51e40a0dbe media: sun4i-csi: Add support for A10 CSI1 camera sensor interface
The A10/A20 Allwinner SoCs have two camera sensor interface blocks,
named CSI0 and CSI1. The two have the same register layouts with
slightly different features:

  - CSI0 has an image signal processor (ISP); CSI1 doesn't

  - CSI0 can support up to four separate channels under CCIR656;
    CSI1 can only support one

  - CSI0 can support up to 16-bit wide bus with YUV422;
    CSI1 can support up to 24-bit wide bus with YUV444

For now the driver doesn't support wide busses, nor CCIR656. So the
only relevant difference is whether a clock needs to be taken and
enabled for the ISP.

Add structs to record the differences, tie them to the compatible
strings, and deal with the ISP clock. Support for the new CSI1
hardware block is added as well.

Chen-Yu Tsai 249b286171 media: sun4i-csi: Deal with DRAM offset
On Allwinner SoCs, some high memory bandwidth devices do DMA directly
over the memory bus (called MBUS), instead of the system bus. These
devices include the CSI camera sensor interface, video (codec) engine,
display subsystem, etc.. The memory bus has a different addressing
scheme without the DRAM starting offset.

Deal with this using the "interconnects" property from the device tree,
or if that is not available, set dev->dma_pfn_offset to PHYS_PFN_OFFSET.

Chen-Yu Tsai 1948dcf0f9 media: sun4i-csi: Fix [HV]sync polarity handling
The Allwinner camera sensor interface has a different definition of
[HV]sync. While the timing diagram uses the names HSYNC and VSYNC,
the note following the diagram and register names use HREF and VREF.
Combined they imply the hardware uses either [HV]REF or inverted
[HV]SYNC. There are also registers to set horizontal skip lengths
in pixels and vertical skip lengths in lines, also known as back
porches.

Fix the polarity handling by using the opposite polarity flag for
the checks. Also rename `[hv]sync_pol` to `[hv]ref_pol` to better
match the hardware register description.

The CLK_POL field specifies whether data is sampled on the falling or
rising edge of PCLK, not whether the data lines are active high or low.
Evidence of this can be found in the timing diagram labeled "horizontal
size setting and pixel clock timing".

Fix the setting by checking the correct flag, V4L2_MBUS_PCLK_SAMPLE_RISING.
While at it, reorder the three polarity flag checks so HSYNC and VSYNC
are grouped together.

This driver supports both the mt9v032 (color) and the mt9v022 (mono)
sensors. Depending on which sensor is used, the format from the sensor is
different. The format.code inside the dev struct holds this information.
The enum mbus and enum frame sizes need to take into account both type of
sensors, not just the color one. To solve this, use the format.code in
these functions instead of the hardcoded bayer color format (which is only
used for mt9v032).

The variable _rate is by ov5640_compute_sys_clk() which returns
zero if the PLL exceeds 1GHz.  Unfortunately, the check to see
if the max PLL1 output is checking 'rate' and not '_rate' and
'rate' does not ever appear to be 0.

This patch changes the check against the returned value of
'_rate' to determine if the PLL1 output exceeds 1GHz.

Adam Ford 5554c80e18 media: ov5640: Put max framerate into table and simplify check
Currently the various modes are placed into a table, but when
ov5640_find_mode is called, it has to double check whether
or not the requested framerate is tolerated by the mode.
The determination is based on checking hact, vact, and frame rate.

Only 640x480 is allowed at 60fps and QSXGA is limited to 15fps, but
as the number of permitted frame rates change, this will begin to
add more and more complexity to the check.

This patch simplifies the check by adding the max framerate
allowed for each mode into the table of modes.  It then compares
the requested framerate to the max permitted in the mode's table.
This reduces the number of comparisions to one down from three
at run-time.

These messages happen at random and do not prevent the receiver from
working. Also I cannot change the features of the IC, therefore they are not
useful. Probably they are not useful at all.

However they fill the console, they accumulate and fill the dmesg log, by
doing this, they prevent me from seeing important message.

Arnd Bergmann 342027c5de media: v4l2-core: fix compat v4l2_buffer handling for time64 ABI
Add support for the four new variants of ioctl commands for 64-bit time_t
in v4l2_buffer.

The existing v4l2_buffer32 structure for the traditional format gets
changed to match the new v4l2_buffer format, and the old layout is
now called v4l2_buffer32_time32. Neither of these matches the native
64-bit architecture format of v4l2_buffer, so both require special
handling in compat code.

Duplicating the existing handlers for the new types is a safe conversion
for now, but unfortunately this may turn into a maintenance burden
later. A larger-scale rework of the compat code might be a better
alternative, but is out of scope of the y2038 work.

Note: x32 support for v4l2_buffer32 has always been broken and remains
so after this change, fixing it would have required even more duplication,
and apparently nobody has cared so far.

Arnd Bergmann 9983b2daf1 media: v4l2-core: fix compat VIDIOC_DQEVENT for time64 ABI
The native code supports the variant of struct v4l2_event for 64-bit
time_t, so add the compat version as well.

Here, a new incompatibility arises: while almost all 32-bit architectures
now use the same layout as 64-bit architectures and the commands can
simply be passed through, on x86 the internal alignment of v4l2_event
is different because of the 64-bit member in v4l2_event_ctrl.

To handle all architectures, this now requires defining four different
versions of the structure to cover all possible combinations. The compat
handling for VIDIOC_DQEVENT32 and VIDIOC_DQEVENT32_TIME32 is now inside
of an #ifdef so it does not get used on architectures other than x86.

Arnd Bergmann 577c89b0ce media: v4l2-core: fix v4l2_buffer handling for time64 ABI
The v4l2_buffer structure contains a 'struct timeval' member that is
defined by the user space C library, creating an ABI incompatibility
when that gets updated to a 64-bit time_t.

As in v4l2_event, handle this with a special case in video_put_user()
and video_get_user() to replace the memcpy there.

Since the structure also contains a pointer, there are now two
native versions (on 32-bit systems) as well as two compat versions
(on 64-bit systems), which unfortunately complicates the compat
handler quite a bit.

Duplicating the existing handlers for the new types is a safe
conversion for now, but unfortunately this may turn into a
maintenance burden later. A larger-scale rework of the
compat code might be a better alternative, but is out of scope
of the y2038 work.

Sparc64 needs a special case because of their special suseconds_t
definition.

Arnd Bergmann 1a6c0b36dd media: v4l2-core: fix VIDIOC_DQEVENT for time64 ABI
The v4l2_event structure contains a 'struct timespec' member that is
defined by the user space C library, creating an ABI incompatibility
when that gets updated to a 64-bit time_t.

While passing a 32-bit time_t here would be sufficient for CLOCK_MONOTONIC
timestamps, simply redefining the structure to use the kernel's
__kernel_old_timespec would not work for any library that uses a copy
of the linux/videodev2.h header file rather than including the copy from
the latest kernel headers.

This means the kernel has to be changed to handle both versions of the
structure layout on a 32-bit architecture. The easiest way to do this
is during the copy from/to user space.

Arnd Bergmann 4a873f3fa5 media: v4l2-core: compat: ignore native command codes
The do_video_ioctl() compat handler converts the compat command
codes into the native ones before processing further, but this
causes problems for 32-bit user applications that pass a command
code that matches a 64-bit native number, which will then be
handled the same way.

Specifically, this breaks VIDIOC_DQEVENT_TIME from user space
applications with 64-bit time_t, as the structure layout is
the same as the native 64-bit layout on many architectures
(x86 being the notable exception).

Change the handler to use the converted command code only for
passing into the native ioctl handler, not for deciding on the
conversion, in order to make the compat behavior match the
native behavior.

Actual support for the 64-bit time_t version of VIDIOC_DQEVENT_TIME
and other commands still needs to be added in a separate patch.

Hans Verkuil ac479b51f3 media: cec: check 'transmit_in_progress', not 'transmitting'
Currently wait_event_interruptible_timeout is called in cec_thread_func()
when adap->transmitting is set. But if the adapter is unconfigured
while transmitting, then adap->transmitting is set to NULL. But the
hardware is still actually transmitting the message, and that's
indicated by adap->transmit_in_progress and we should wait until that
is finished or times out before transmitting new messages.

As the original commit says: adap->transmitting is the userspace view,
adap->transmit_in_progress reflects the hardware state.

However, if adap->transmitting is NULL and adap->transmit_in_progress
is true, then wait_event_interruptible is called (no timeout), which
can get stuck indefinitely if the CEC driver is flaky and never marks
the transmit-in-progress as 'done'.

So test against transmit_in_progress when deciding whether to use
the timeout variant or not, instead of testing against adap->transmitting.

The AVerMedia CE310B is a simple composite + S-Video + stereo audio
capture card, and uses only the CX23888 to perform all of these

I've tested both video inputs and the audio interface and confirmed that
they're all working. However, there are some issues:

* Sometimes when I switch inputs the video signal turns black and can't
  be recovered until the system is rebooted. I haven't been able to
  determine the cause of this behavior, nor have I found a solution to
  fix it or any workarounds other than rebooting.
* The card sometimes seems to have trouble syncing to the video signal,
  and some of the VBI data appears as noise at the top of the frame, but
  I assume that to be a result of my very noisy RF environment and the
  card's unshielded input traces rather than a configuration issue.

Hans Verkuil d51224b73d media: cec: check 'transmit_in_progress', not 'transmitting'
Currently wait_event_interruptible_timeout is called in cec_thread_func()
when adap->transmitting is set. But if the adapter is unconfigured
while transmitting, then adap->transmitting is set to NULL. But the
hardware is still actually transmitting the message, and that's
indicated by adap->transmit_in_progress and we should wait until that
is finished or times out before transmitting new messages.

As the original commit says: adap->transmitting is the userspace view,
adap->transmit_in_progress reflects the hardware state.

However, if adap->transmitting is NULL and adap->transmit_in_progress
is true, then wait_event_interruptible is called (no timeout), which
can get stuck indefinitely if the CEC driver is flaky and never marks
the transmit-in-progress as 'done'.

So test against transmit_in_progress when deciding whether to use
the timeout variant or not, instead of testing against adap->transmitting.

Benoit Parrot 5f9f2fb7c4 media: ti-vpe: cal: Fix ths_term/ths_settle parameters
The current method to calculate the ddr clk period is wrong.
Therefore the ths_term calculation is incorrect.
Also it was wrongly assumed that the ths_settle parameter
was based on the control clock instead of the pixel clock.

Since the DPHY can tolerate quite a bit a of variation,
capture was still mostly working with the 2 tested modes
when the pixel clock was close to the control clock
(i.e. 96 Mhz). But it would quickly stops working when
using different modes or when customers used different
sensors altogether.

Calculating the DDRClk period needs to take into account
the pixel bit width and the number of active data lanes.

Based on the latest technical reference manual these
parameters should now be calculated as follows:

THS_TERM: Programmed value = floor(20 ns/DDRClk period)
THS_SETTLE: Programmed value = floor(105 ns/DDRClk period) + 4

Also originally 'depth' was used to represent the number of
bits a pixel would use once stored in memory (i.e. the
container size). To accurately calculate the THS_* parameters
we need to use the actual number of bits per pixels coming
in from the sensor. So we are renaming 'depth' to 'bpp' (bits
per pixels) and update the format table to show the actual
number of bits per pixel being received.

The "container" size will be derived from the "bpp" value.

Linus Torvalds 0da522107e compat_ioctl: remove most of fs/compat_ioctl.c
As part of the cleanup of some remaining y2038 issues, I came to
 fs/compat_ioctl.c, which still has a couple of commands that need support
 for time64_t.
 
 In completely unrelated work, I spent time on cleaning up parts of this
 file in the past, moving things out into drivers instead.
 
 After Al Viro reviewed an earlier version of this series and did a lot
 more of that cleanup, I decided to try to completely eliminate the rest
 of it and move it all into drivers.
 
 This series incorporates some of Al's work and many patches of my own,
 but in the end stops short of actually removing the last part, which is
 the scsi ioctl handlers. I have patches for those as well, but they need
 more testing or possibly a rewrite.

Linus Torvalds 9a3d7fd275 Driver core patches for 5.5-rc1
Here is the "big" set of driver core patches for 5.5-rc1
 
 There's a few minor cleanups and fixes in here, but the majority of the
 patches in here fall into two buckets:
   - debugfs api cleanups and fixes
   - driver core device link support for boot dependancy issues
 
 The debugfs api cleanups are working to slowly refactor the debugfs apis
 so that it is even harder to use incorrectly.  That work has been
 happening for the past few kernel releases and will continue over time,
 it's a long-term project/goal
 
 The driver core device link support missed 5.4 by just a bit, so it's
 been sitting and baking for many months now.  It's from Saravana Kannan
 to help resolve the problems that DT-based systems have at boot time
 with dependancy graphs and kernel modules.  Turns out that no one has
 actually tried to build a generic arm64 kernel with loads of modules and
 have it "just work" for a variety of platforms (like a distro kernel)
 The big problem turned out to be a lack of depandancy information
 between different areas of DT entries, and the work here resolves that
 problem and now allows devices to boot properly, and quicker than a
 monolith kernel.
 
 All of these patches have been in linux-next for a long time with no
 reported issues.

Takashi Iwai 3b316a8f60 media: tw686x: audio: Avoid non-standard macro usage
Pass the device pointer from the PCI pointer directly, instead of a
non-standard macro.  The macro didn't give any better readability.

Takashi Iwai ef99d99b2f media: solo6x10: Remove superfluous snd_dma_continuous_data()
The recent change (commit 08422d2c559d: "ALSA: memalloc: Allow NULL
device for SNDRV_DMA_TYPE_CONTINOUS type") made the PCM preallocation
helper accepting NULL as the device pointer for the default usage.
Drop the snd_dma_continuous_data() usage that became superfluous from
the callers.

Hans Verkuil dca6b3733a media: Revert "media: mtk-vcodec: Remove extra area allocation in an input buffer on encoding"
This reverts commit 3192b2ca79.

There are indications that this patch causes problems on some
platforms due to some hardware prefetch. Reverting this patch
for now until this is better understood.
