Stanimir Varbanov 703528005e [media] media: venus: enable building of Venus video driver
This adds Venus driver Makefile and changes v4l2 platform
Makefile/Kconfig in order to enable building of the driver.

Note that in this initial version the COMPILE_TEST-ing is not
supported because the drivers specific to ARM builds are still
in process of enabling the aforementioned compile testing.
Once that disadvantage is fixed the Venus driver compile testing
will be possible with follow-up changes.

This is the implementation of HFI. It is charged with the
responsibility to comunicate with the firmware through an
interface commands and messages.

 - hfi.c has interface functions used by the core, decoder
and encoder parts to comunicate with the firmware. For example
there are functions for session and core initialisation.

 - hfi_cmds has packetization operations which preparing
packets to be send from host to firmware.

 - hfi_msgs takes care of messages sent from firmware to the
host.

Stanimir Varbanov af2c3834c8 [media] media: venus: adding core part and helper functions
* core.c has implemented the platform driver methods, file
operations and v4l2 registration.

 * helpers.c has implemented common helper functions for:
   - buffer management

   - vb2_ops and functions for format propagation,

   - functions for allocating and freeing buffers for
   internal usage. The buffer parameters describing internal
   buffers depends on current format, resolution and codec.

   - functions for calculation of current load of the
   hardware. Depending on the count of instances and
   resolutions it selects the best clock rate for the video
   core.

This driver can handle SoC internal and external video bus multiplexers,
controlled by mux controllers provided by the mux controller framework,
such as MMIO register bitfields or GPIOs. The subdevice passes through
the mbus configuration of the active input to the output side.

Since the mux framework is not yet merged, this driver contains
temporary mmio-mux support to work without the framework. The driver
should be converted to use the multiplexer API once the "mux: minimal
mux subsystem" and "mux: mmio-based syscon mux controller" patches are
merged.

Ramesh Shanmugasundaram 7625ee981a [media] media: platform: rcar_drif: Add DRIF support
This patch adds Digital Radio Interface (DRIF) support to R-Car Gen3 SoCs.
The driver exposes each instance of DRIF as a V4L2 SDR device. A DRIF
device represents a channel and each channel can have one or two
sub-channels respectively depending on the target board.

DRIF supports only Rx functionality. It receives samples from a RF
frontend tuner chip it is interfaced with. The combination of DRIF and the
tuner device, which is registered as a sub-device, determines the receive
sample rate and format.

In order to be compliant as a V4L2 SDR device, DRIF needs to bind with
the tuner device, which can be provided by a third party vendor. DRIF acts
as a slave device and the tuner device acts as a master transmitting the
samples. The driver allows asynchronous binding of a tuner device that
is registered as a v4l2 sub-device. The driver can learn about the tuner
it is interfaced with based on port endpoint properties of the device in
device tree. The V4L2 SDR device inherits the controls exposed by the
tuner device.

The device can also be configured to use either one or both of the data
pins at runtime based on the master (tuner) configuration.

Add a new capability CEC_CAP_NEEDS_HPD. If this capability is set
then the hardware can only use CEC if the HDMI Hotplug Detect pin
is high. Such hardware cannot handle the corner case in the CEC specification
where it is possible to transmit messages even if no hotplug signal is
present (needed for some displays that turn off the HPD when in standby,
but still have CEC enabled).

Typically hardware that needs this capability have the HPD wired to the CEC
block, often to a 'power' or 'active' pin.

Johannes Berg 4df864c1d9 networking: make skb_put & friends return void pointers
It seems like a historic accident that these return unsigned char *,
and in many places that means casts are required, more often than not.

Make these functions (skb_put, __skb_put and pskb_put) return void *

where the unsigned char pointer was used directly, all done with the
following spatch:

    expression SKB, LEN;
    typedef u8;
    identifier fn = { skb_put, __skb_put };
    @@
    - *(fn(SKB, LEN))

    identifier fn = { skb_put, __skb_put };
    type T;
    @@
    - E = ((T *)(fn(SKB, LEN)))
    + E = fn(SKB, LEN)

which actually doesn't cover pskb_put since there are only three
users overall.

A handful of stragglers were converted manually, notably a macro in
drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many
instances in net/bluetooth/hci_sock.c. In the former file, I also
had to fix one whitespace problem spatch introduced.

Alexandre Courbot 17d716e926 [media] s5p-jpeg: fix recursive spinlock acquisition
v4l2_m2m_job_finish(), which is called from the interrupt handler with
slock acquired, can call the device_run() hook immediately if another
context was in the queue. This hook also acquires slock, resulting in
a deadlock for this scenario.

Fix this by releasing slock right before calling v4l2_m2m_job_finish().
This is safe to do as the state of the hardware cannot change before
v4l2_m2m_job_finish() is called anyway.

David Härdeman 18726a349d [media] rc-core: cleanup rc_register_device pt2
Now that rc_register_device() is reorganised, the dev->initialized
hack can be removed. Any driver which calls rc_register_device()
must be prepared for the device to go live immediately.

The dev->initialized commits that are relevant are commit c73bbaa4ec
("[media] rc-core: don't lock device at rc_register_device()") and
commit 08aeb7c9a4 ("[media] rc: add locking to fix register/show race").

The original problem was that show_protocols() would access
dev->rc_map.* and various other bits which are now properly
initialized before device_add() is called.

At the same time, remove the bogus "device is being removed" check.

The display buffers must be mapped for DMA through the device that
performs memory access. Expose an API to map and unmap memory through
the VSP device to be used by the DU.

As all the buffers allocated by the DU driver are coherent, we can skip

revisited when support for non-coherent buffers will be added to the DU
driver.

Magnus Damm 2cc2137ffb v4l: vsp1: Map the DL and video buffers through the proper bus master
On Gen2 hardware the VSP1 is a bus master and accesses the display list
and video buffers through DMA directly. On Gen3 hardware, however,
memory accesses go through a separate IP core called FCP.

The VSP1 driver unconditionally maps DMA buffers through the VSP device.
While this doesn't cause any practical issue so far, DMA mappings will
be incorrect as soon as we will enable IOMMU support for the FCP on Gen3
platforms, resulting in IOMMU faults.

Fix this by mapping all buffers through the FCP device if present, and
through the VSP1 device as usual otherwise.

Hans Verkuil b94aac64a4 [media] cec: race fix: don't return -ENONET in cec_receive()
When calling CEC_RECEIVE do not check if the adapter is configured.
Typically CEC_RECEIVE is called after a select() and if that indicates
that there are messages in the receive queue, then you should always be
able to dequeue a message.

The race condition here is that a message has been received and is
queued, so select() tells userspace that a message is available. But
before the application calls CEC_RECEIVE the adapter is unconfigured
(e.g. the HDMI cable is removed). Now select will always report that
there is a message, but calling CEC_RECEIVE will always return -ENONET
because the adapter is no longer configured and so will never actually
dequeue the message.

There is really no need for this check, and in fact the ENONET error
code was never documented for CEC_RECEIVE. This may have been a left-over
of old code that was never updated.

Fix this by moving the mdp component nodes up a level such that they are
siblings of mdp and all other SoC subsystems.  This also simplifies the
device tree.

Although it fixes iommu assignment issue, it also break compatibility
with old device tree. So, the patch in driver is needed to iterate over

Anton Blanchard cc20ba4ed8 [media] ir-spi: Fix issues with lirc API
The ir-spi driver has 2 issues which prevents it from working with
lirc:

1. The ir-spi driver uses 16 bits of SPI data to create one cycle of
the waveform. As such our SPI clock needs to be 16x faster than the
carrier frequency.

The driver is inconsistent in how it currently handles this. It
initializes it to the carrier frequency:

But the commit message has some example code which initialises it
to 16x the carrier frequency:

To maintain compatibility with lirc, always do the frequency adjustment
in the driver.

2. lirc presents pulses in microseconds, but the ir-spi driver treats
them as cycles of the carrier. Similar to other lirc drivers, do the
conversion with DIV_ROUND_CLOSEST().

Niklas Söderlund 82ec4ca9b5 [media] rcar-vin: allow switch between capturing modes when stalling
If userspace can't feed the driver with buffers as fast as the driver
consumes them the driver will stop video capturing and wait for more
buffers from userspace, the driver is stalled. Once it have been feed
one or more free buffers it will recover from the stall and resume
capturing.

Instead of continue to capture using the same capture mode as before the
stall allow the driver to choose between single and continuous mode
based on free buffer availability. Do this by stopping capturing when
the driver becomes stalled and restart capturing once it continues. By
doing
this the capture mode will be evaluated each time the driver is
recovering from a stall.

This behavior is needed to fix a bug where continuous capturing mode is
used, userspace is about to stop the stream and is waiting for the last
buffers to be returned from the driver and is not queuing any new
buffers. In this case the driver becomes stalled when there are only 3
buffers remaining streaming will never resume since the driver is
waiting for userspace to feed it more buffers before it can continue
streaming.  With this fix the driver will then switch to single capture
mode for the last 3 buffers and a deadlock is avoided. The issue can be
demonstrated using yavta.

This fix also allow the driver to switch to single capture mode if
userspace doesn't feed it buffers fast enough. Or the other way around,
if userspace suddenly feeds the driver buffers faster it can switch to
continues capturing mode.

Niklas Söderlund 996ce3afbe [media] rcar-vin: select capture mode based on free buffers
Instead of selecting single or continuous capture mode based on how many
buffers userspace intends to give us select capture mode based on number
of free buffers we can allocate to hardware when the stream is started.

This change is a prerequisite to enable the driver to switch from
continuous to single capture mode (or the other way around) when the
driver is stalled by userspace not feeding it buffers as fast as it
consumes it.

   - A driver fix at rainshadow-cec

  IMHO, the one that affects most people in this series is a build fix:
  if you try to build the Kernel with W=1 or using gcc7 and
  all[yes|mod]config, build will fail due to -Werror at atomisp

Niklas Söderlund 0ad1786461 [media] rcar-vin: fix standard in input enumeration
The driver supports a single input only, which can be either analog or
digital. If the subdevice supports dv_timings_cap the input is digital
and the driver should not fill in the standard.

Niklas Söderlund 831081626f [media] rcar-vin: fix how pads are handled for v4l2 subdevice operations
The rcar-vin driver only uses one pad, pad number 0.

- All v4l2 operations that did not check that the requested operation
  was for pad 0 have been updated with a check to enforce this.

- All v4l2 operations that stored (and later restored) the requested pad
  before substituting it for the subdevice pad number have been updated
  to not store the incoming pad and simply restore it to 0 after the
  subdevice operation is complete.

Sakari Ailus ca50c197bd [media] v4l: fwnode: Support generic fwnode for parsing standardised properties
The fwnode_handle is a more generic way than OF device_node to describe
firmware nodes. Instead of the OF API, use more generic fwnode API to
obtain the same information.

As the V4L2 fwnode support will be required by a small minority of e.g.
ACPI based systems (the same might actually go for OF), make this a module
instead of embedding it in the videodev module.

The origins of the V4L2 fwnode framework is in the V4L2 OF framework.

Devin Heitmueller d9928a115a [media] xc5000: Don't spin waiting for analog lock
The xc5000 driver should not be spinning waiting for an analog lock.
The ioctl() should be returning immediately and the application is
responsible for polling for lock status.

This behavior isn't very visible in cases where you tune to a valid
channel, since lock is usually achieved much faster than 400ms.
However it is highly visible where doing things like changing video
standards, which sends tuning request for a frequency that is
almost never going to have an actual channel on it.

Also fixup the return values to treat zero as success and an actual
error code on error (to be consistent with other functions).  Note
this change has no practical effect at this time as none of the
callers inspect the return value.

Devin Heitmueller d90b336f3f [media] mxl111sf: Fix driver to use heap allocate buffers for USB messages
The recent changes in 4.9 to mandate USB buffers be heap allocated
broke this driver, which was allocating the buffers on the stack.
This resulted in the device failing at initialization.

Introduce dedicated send/receive buffers as part of the state
structure, and add a mutex to protect access to them.

Note: we also had to tweak the API to mxl111sf_ctrl_msg to pass
the pointer to the state struct rather than the device, since
we need it inside the function to access the buffers and the
mutex.  This patch adjusts the callers to match the API change.

Devin Heitmueller 4e0973a918 [media] cx88: Fix regression in initial video standard setting
Setting initial standard at the top of cx8800_initdev would cause the
first call to cx88_set_tvnorm() to return without programming any
registers (leaving the driver saying it's set to NTSC but the hardware
isn't programmed).  Even worse, any subsequent attempt to explicitly
set it to NTSC-M will return success but actually fail to program the
underlying registers unless first changing the standard to something
other than NTSC-M.

Set the initial standard later in the process, and make sure the field
is zero at the beginning to ensure that the call always goes through.

This regression was introduced in the following commit:

Petr Cvek e3b4d10cc0 [media] pxa_camera: fix module remove codepath for v4l2 clock
The conversion from soc_camera omitted a correct handling of the clock
gating for a sensor. When the pxa_camera driver module was removed it
tried to unregister clk, but this caused a similar warning:

  WARNING: CPU: 0 PID: 6740 at drivers/media/v4l2-core/v4l2-clk.c:278
  v4l2_clk_unregister(): Refusing to unregister ref-counted 0-0030 clock!

The clock was at time still refcounted by the sensor driver. Before
the removing of the pxa_camera the clock must be dropped by the sensor
driver. This should be triggered by v4l2_async_notifier_unregister() call
which removes sensor driver module too, calls unbind() function and then
tries to probe sensor driver again. Inside unbind() we can safely
unregister the v4l2 clock as the sensor driver got removed. The original
v4l2_clk_unregister() should be put inside test as the clock can be
already unregistered from unbind(). If there was not any bound sensor
the clock is still present.

The codepath is practically a copy from the old soc_camera. The bug was
tested with a pxa_camera+ov9640 combination during the conversion
of the ov9640 from the soc_camera.

David Härdeman 0f7c4063f8 [media] ir-lirc-codec: let lirc_dev handle the lirc_buffer
ir_lirc_register() currently creates its own lirc_buffer before
passing the lirc_driver to lirc_register_driver().

When a module is later unloaded, ir_lirc_unregister() gets called
which performs a call to lirc_unregister_driver() and then free():s
the lirc_buffer.

The problem is that:

a) there can still be a userspace app holding an open lirc fd
   when lirc_unregister_driver() returns; and

b) the lirc_buffer contains "wait_queue_head_t wait_poll" which
   is potentially used as long as any userspace app is still around.

The result is an oops which can be triggered quite easily by a
userspace app monitoring its lirc fd using epoll() and not closing
the fd promptly on device removal.

The minimalistic fix is to let lirc_dev create the lirc_buffer since
lirc_dev will then also free the buffer once it believes it is safe to
do so.

David Härdeman b2aceb739b [media] rc-core: fix input repeat handling
The call to input_register_device() needs to take place
before the repeat parameters are set or the input subsystem
repeat handling will be disabled (as was already noted in
the comments in that function).

Merge tag 'hwparam-20170420' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Pull hw lockdown support from David Howells:
 "Annotation of module parameters that configure hardware resources
  including ioports, iomem addresses, irq lines and dma channels.

  This allows a future patch to prohibit the use of such module
  parameters to prevent that hardware from being abused to gain access
  to the running kernel image as part of locking the kernel down under
  UEFI secure boot conditions.

  Annotations are made by changing:

        module_param(n, t, p)
        module_param_named(n, v, t, p)
        module_param_array(n, t, m, p)

  to:

        module_param_hw(n, t, hwtype, p)
        module_param_hw_named(n, v, t, hwtype, p)
        module_param_hw_array(n, t, hwtype, m, p)

  where the module parameter refers to a hardware setting

  hwtype specifies the type of the resource being configured. This can
  be one of:

        ioport          Module parameter configures an I/O port
        iomem           Module parameter configures an I/O mem address
        ioport_or_iomem Module parameter could be either (runtime set)
        irq             Module parameter configures an I/O port
        dma             Module parameter configures a DMA channel
        dma_addr        Module parameter configures a DMA buffer address
        other           Module parameter configures some other value

  Note that the hwtype is compile checked, but not currently stored (the
  lockdown code probably won't require it). It is, however, there for
  future use.

  A bonus is that the hwtype can also be used for grepping.

  The intention is for the kernel to ignore or reject attempts to set
  annotated module parameters if lockdown is enabled. This applies to
  options passed on the boot command line, passed to insmod/modprobe or
  direct twiddling in /sys/module/ parameter files.

  The module initialisation then needs to handle the parameter not being
  set, by (1) giving an error, (2) probing for a value or (3) using a
  reasonable default.

  What I can't do is just reject a module out of hand because it may
  take a hardware setting in the module parameters. Some important
  modules, some ipmi stuff for instance, both probe for hardware and
  allow hardware to be manually specified; if the driver is aborts with
  any error, you don't get any ipmi hardware.

  Further, trying to do this entirely in the module initialisation code
  doesn't protect against sysfs twiddling.

  [!] Note that in and of itself, this series of patches should have no
      effect on the the size of the kernel or code execution - that is
      left to a patch in the next series to effect. It does mark
      annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
      an already existing field"

Here is the big staging tree update for 4.12-rc1.  And it's a big one,

 well, yet-another-wifi driver, new IIO drivers, and a new crypto
 accelerator.  We also deleted a bunch of stuff, mostly in patch
 cleanups, but also the Android ION code has shrunk a lot, and the
 Android low memory killer driver was finally deleted, much to the
 celebration of the -mm developers.
 
 All of these have been in linux-next with a few build issues that will

David Howells 5a8fc6a3ce Annotate hardware config module parameters in drivers/media/
When the kernel is running in secure boot mode, we lock down the kernel to
prevent userspace from modifying the running kernel image.  Whilst this
includes prohibiting access to things like /dev/mem, it must also prevent
access by means of configuring driver modules in such a way as to cause a
device to access or modify the kernel image.

To this end, annotate module_param* statements that refer to hardware
configuration and indicate for future reference what type of parameter they
specify.  The parameter parser in the core sees this information and can
skip such parameters with an error message if the kernel is locked down.
The module initialisation then runs as normal, but just sees whatever the
default values for those parameters is.

Note that we do still need to do the module initialisation because some
drivers have viable defaults set in case parameters aren't specified and
some drivers support automatic configuration (e.g. PNP or PCI) in addition
to manually coded parameters.

This patch annotates drivers in drivers/media/.

Logan Gunthorpe f9b67f0014 dma-buf: Rename dma-ops to prevent conflict with kunmap_atomic macro
Seeing the kunmap_atomic dma_buf_ops share the same name with a macro
in highmem.h, the former can be aliased if any dma-buf user includes
that header.

I'm personally trying to include highmem.h inside scatterlist.h and this
breaks the dma-buf code proper.

Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP.

To maintain consistency I've renamed all four of kmap* and kunmap* to be
map* and unmap*. (Even though only kmap_atomic presently conflicts.)

Frank Schaefer 7f140fc206 [media] ov2640: fix vflip control
Enabling vflip currently causes wrong colors.
It seems that (at least with the current sensor setup) REG04_VFLIP_IMG only
changes the vertical readout direction.
Because pixels are arranged RGRG... in odd lines and GBGB... in even lines,
either a one line shift or even/odd line swap is required, too, but
apparently this doesn't happen.

I finally figured out that this can be done manually by setting
REG04_VREF_EN.
Looking at hflip, it turns out that bit REG04_HREF_EN is set there
permanetly, but according to my tests has no effect on the pixel readout
order.
So my conclusion is that the current documentation of sensor register 0x04
is wrong (has changed after preliminary datasheet version 2.2).

I'm pretty sure that automatic vertical line shift/switch can be enabled,
too, but until anyone finds ot how this works, we have to stick with manual
switching.

1) Simple AWB: assumes the average color is gray

   - doesn't work well if captured area contains unbalanced colors
     (e.g. large blue background)

2) Advanced AWB: uses color temperature information

The em28xx driver can use ov2640, but it doesn't depend
(or use) the GPIOLIB in order to power off/on the sensor.

So, as we want to allow both usages with and without
GPIOLIB, make its dependency optional.

Hans Verkuil 56a263aaa0 [media] cec: Kconfig cleanup
The Kconfig options for the CEC subsystem were a bit messy. In
addition there were two cec sources (cec-edid.c and cec-notifier.c)
that were outside of the media/cec directory, which was weird.

Move those sources to media/cec as well.

The cec-edid and cec-notifier functionality is now part of the cec
module and these are no longer separate modules.

Also remove the MEDIA_CEC_EDID config option and include it with the
main CEC config option (which defined CEC_EDID anyway).

Added static inlines to cec-edid.h for dummy functions when CEC_CORE
isn't defined.

CEC drivers should now depend on CEC_CORE.

CEC drivers that need the cec-notifier functionality must explicitly
select CEC_NOTIFIER.

The s5p-cec and stih-cec drivers depended on VIDEO_DEV instead of
CEC_CORE, fix that as well.

Of course we could use speculative default values for unknown sensors,

Instead, just don't treat the device as camera.

Frank Schaefer 4d58443696 [media] em28xx: simplify ID-reading from Micron sensors
Use i2c_smbus_read_word_data() instead of i2c_master_send() and
i2c_master_recv() for reading the ID of Micorn sensors.

i2c_smbus_read_word_data() assumes that byes are in little-endian,
so, it uses:
	data->word = msgbuf1[0] | (msgbuf1[1] << 8);

However, Micron datasheet describes the ID as if they were read
in big-endian. So, we need to change the byte order in order to
match the ID number as described on their datasheets.

Jasmin J e7080d4471 [media] media/dvb-core: Race condition when writing to CAM
It started with a sporadic message in syslog: "CAM tried to send a
buffer larger than the ecount size" This message is not the fault
itself, but a consecutive fault, after a read error from the CAM. This
happens only on several CAMs, several hardware, and of course sporadic.

It is a consecutive fault, if the last read from the CAM did fail. I
guess this will not happen on all CAMs, but at least it did on mine.
There was a write error to the CAM and during the re-initialization
procedure, the CAM finished the last read, although it got a RS.

The write error to the CAM happened because a race condition between HC
write, checking DA and FR.

This patch added an additional check for DA(RE), just after checking FR.
It is important to read the CAMs status register again, to give the CAM
the necessary time for a proper reaction to HC. Please note the
description within the source code (patch below).

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.

But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

'Reset' loop does not look correct. I tested it very many times and
it never repeated those commands. If problem, it tries to solve,
really occurs on some situations better solution should be find out.

There is another patch which does not have such hackish looking loop.
Lets change to it.

The XV601/709 encodings are special: they signal limited range, but use the full range
to encode a larger gamut with R', G' and B' values outside the [0-1] range.

So don't clamp to limited range for these two encodings.
