Sean Young a10c3d5ff9 pwm: Rename pwm_apply_state() to pwm_apply_might_sleep()
[ Upstream commit c748a6d77c06a78651030e17da6beb278a1c9470 ]

In order to introduce a pwm api which can be used from atomic context,
we will need two functions for applying pwm changes:

	int pwm_apply_might_sleep(struct pwm *, struct pwm_state *);
	int pwm_apply_atomic(struct pwm *, struct pwm_state *);

This commit just deals with renaming pwm_apply_state(), a following
commit will introduce the pwm_apply_atomic() function.

Geert Uytterhoeven 7684d956d7 drm/ssd130x: Fix screen clearing
[ Upstream commit 4dbce3d6fea59e1df1d1a35aacea0c186f72107a ]

Due to the reuse of buffers, ssd130x_clear_screen() no longers clears
the screen, but merely redraws the last image that is residing in the
intermediate buffer.

As there is no point in clearing the intermediate buffer and transposing
an all-black image, fix this by just clearing the HW format buffer, and
writing it to the panel.

drm/ssd130x: Use shadow-buffer helpers when managing plane's state
The commit 45b58669e5 ("drm/ssd130x: Allocate buffer in the plane's
.atomic_check() callback") moved the buffers allocation to be done in
the primary plane's .atomic_check() callback.

But it missed that since the driver uses a shadow-buffered plane, the
__drm_gem_{reset,duplicate,destroy}_shadow_plane() helper functions
must be used in the struct drm_plane_funcs handlers.

This was missed because the mentioned commit did not remove the macro
DRM_GEM_SHADOW_PLANE_FUNCS, which leads to the custom plane's atomic
state management handlers to not be used.

drm/ssd130x: Allocate buffer in the plane's .atomic_check() callback
Drivers are not allowed to fail after drm_atomic_helper_swap_state() has
been called and the new atomic state is stored into the current sw state.

Since the struct ssd130x_device .data_array is allocated in the encoder's
.atomic_enable callback, the operation can fail and this is after the new
state has been stored. So it can break an atomic mode settings assumption.

Fix this by having custom helpers to allocate, duplicate and destroy the
plane state, that will take care of allocating and freeing these buffers.

drm/ssd130x: Change pixel format used to compute the buffer size
The commit e254b584db ("drm/ssd130x: Remove hardcoded bits-per-pixel in
ssd130x_buf_alloc()") used a pixel format info rather than a hardcoded bpp
to calculate the size of the buffer allocated to store the native pixels.

But it wrongly used the DRM_FORMAT_C1 fourcc pixel format. That is for
color-indexed frame buffer formats, while the ssd103x controllers don't
support different single-channel colors nor a Color Lookup Table (CLUT).

So the correct pixel format to use in this case is DRM_FORMAT_R1 instead.

Since both formats use a eight pixels/byte, there is no functional change
in practice by this patch. Still, the correct pixel format should be used.

drm/ssd130x: Remove hardcoded bits-per-pixel in ssd130x_buf_alloc()
The driver only supports OLED controllers that have a native DRM_FORMAT_C1
pixel format and that is why it has harcoded a division of the width by 8.

But the driver might be extended to support devices that have a different
pixel format. So it's better to use the struct drm_format_info helpers to
compute the size of the buffer, used to store the pixels in native format.

drm/ssd130x: Don't allocate buffers on each plane update
The resolutions for these panels are fixed and defined in the Device Tree,
so there's no point to allocate the buffers on each plane update and that
can just be done once.

Let's do the allocation and free on the encoder enable and disable helpers
since that's where others initialization and teardown operations are done.

drm/ssd130x: Make default width and height to be controller dependent
Currently the driver hardcodes the default values to 96x16 pixels but this
default resolution depends on the controller. The datasheets for the chips
describes the following display controller resolutions:

 - SH1106:  132 x 64 Dot Matrix OLED/PLED
 - SSD1305: 132 x 64 Dot Matrix OLED/PLED
 - SSD1306: 128 x 64 Dot Matrix OLED/PLED
 - SSD1307: 128 x 39 Dot Matrix OLED/PLED
 - SSD1309: 128 x 64 Dot Matrix OLED/PLED

Add this information to the devices' info structures, and use it set as a
default if not defined in DT rather than hardcoding to an arbitrary value.

drm/ssd130x: Init display before the SSD130X_DISPLAY_ON command
Commit 622113b9f1 ("drm/ssd130x: Replace simple display helpers with the
atomic helpers") changed the driver to just use the atomic helpers instead
of the simple KMS abstraction layer.

But the commit also made a subtle change on the display power sequence and
initialization order, by moving the ssd130x_power_on() call to the encoder
.atomic_enable handler and the ssd130x_init() call to CRTC .reset handler.

Before this change, both ssd130x_power_on() and ssd130x_init() were called
in the simple display pipeline .enable handler, so the display was already
initialized by the time the SSD130X_DISPLAY_ON command was sent.

For some reasons, it only made the ssd130x SPI driver to fail but the I2C
was still working. That is the reason why the bug was not noticed before.

To revert to the old driver behavior, move the ssd130x_init() call to the
encoder .atomic_enable as well. Besides fixing the panel not being turned
on when using SPI, it also gets rid of the custom CRTC .reset callback.

drm/ssd130x: Silence a `dubious: x & !y` warning
The sparse tool complains with the following warning:

  CHECK   drivers/gpu/drm/solomon/ssd130x.c

This seems to be a false positive in my opinion but still we can silence
the tool while making the code easier to read. Let's also add a comment,
to explain why the "com_seq" logical not is used rather than its value.

drm/crtc-helper: Add a drm_crtc_helper_atomic_check() helper
Provides a default CRTC state check handler for CRTCs that only have one
primary plane attached.

There are some drivers that duplicate this logic in their helpers, such as
simpledrm and ssd130x. Factor out this common code into a CRTC helper and
make drivers use it.

drm/ssd130x: Do not call drm_atomic_add_affected_planes()
There's no need to add planes to the atomic state. Remove the call
to drm_atomic_add_affected_planes() from ssd130x.

On full modesets, the DRM helpers already add a CRTC's planes to the
atomic state; see drm_atomic_helper_check_modeset(). There's no reason
to call drm_atomic_add_affected_planes() unconditionally in the CRTC's
atomic_check() in ssd130x. It's also too late, as the atomic_check()
of the added planes will not be called before the commit.

The drm_atomic_helper_damage_merged() helper merges all the damage clips

to each other, the resulting rectangle could be quite big.

Instead of using that function helper, iterate over all the damage clips

drm/ssd130x: Use drm_atomic_get_new_plane_state()
The struct drm_plane .state shouldn't be accessed directly but instead the

drm/plane-helper: Add a drm_plane_helper_atomic_check() helper
Provides a default plane state check handler for primary planes that are a
fullscreen scanout buffer and whose state scale and position can't change.

There are some drivers that duplicate this logic in their helpers, such as
simpledrm and ssd130x. Factor out this common code into a plane helper and
make drivers use it.

drm/ssd130x: Replace simple display helpers with the atomic helpers
The simple display pipeline is a set of helpers that can be used by DRM
drivers to avoid dealing with all the needed components and just define
a few functions to operate a simple display device with one full-screen
scanout buffer feeding a single output.

But it is arguable that this provides the correct level of abstraction
for simple drivers, and recently some have been ported from using these
simple display helpers to use the regular atomic helpers instead.

The rationale for this is that the simple display pipeline helpers don't
hide that much of the DRM complexity, while adding an indirection layer
that conflates the concepts of CRTCs and planes. This makes the helpers
less flexible and harder to be reused among different graphics drivers.

Also, for simple drivers, using the full atomic helpers doesn't require
a lot of additional code. So adding a simple display pipeline layer may
not be worth it.

For these reasons, let's follow that trend and make ssd130x a plain DRM
driver that creates its own primary plane, CRTC, enconder and connector.

Uwe Kleine-König ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

drm/ssd130x: Use new regmap bulk write support to drop custom bus
Data writes for the ssd130x 4-wire SPI protocol need special handling, due
the Data/Command control (D/C) pin having to be toggled prior to the write.

The regmap API only allowed drivers to provide .reg_{read,write} callbacks
to do per register read/write, but didn't provide a way for drivers to do
the same for bulk read/writes.

For this reason, a custom regmap bus was used by the driver just to define
a bulk write callback that implements the D/C pin toggling. But the regmap
API has been extended to support defining bulk read/write handlers, so the
custom regmap bus is not needed anymore and could just be dropped.

drm/ssd130x: Only define a SPI device ID table when built as a module
The kernel test robot reports a compile warning due the ssd130x_spi_table
variable being defined but not used. This happen when ssd130x-spi driver
is built-in instead of being built as a module, i.e:

  CC      drivers/gpu/drm/solomon/ssd130x-spi.o
  AR      drivers/base/firmware_loader/built-in.a
  AR      drivers/base/built-in.a

      |                                   ^~~~~~~~~~~~~~~~~

The driver shouldn't need a SPI device ID table and only have an OF device
ID table, but the former is needed to workaround an issue in the SPI core.
This always reports a MODALIAS of the form "spi:<device>" even for devices
registered through Device Trees.

But the table is only needed when the driver built as a module to populate
the .ko alias info. It's not needed when the driver is built-in the kernel.

drm/solomon: Add SSD130x OLED displays SPI support
The ssd130x driver only provides the core support for these devices but it
does not have any bus transport logic. Add a driver to interface over SPI.

There is a difference in the communication protocol when using 4-wire SPI
instead of I2C. For the latter, a control byte that contains a D/C# field
has to be sent. This field tells the controller whether the data has to be
written to the command register or to the graphics display data memory.

But for 4-wire SPI that control byte is not used, instead a real D/C# line
must be pulled HIGH for commands data and LOW for graphics display data.

For this reason the standard SPI regmap can't be used and a custom .write
bus handler is needed.

drm/solomon: Move device info from ssd130x-i2c to the core driver
These are declared in the ssd130x-i2c transport driver but the information
is not I2C specific, and could be used by other SSD130x transport drivers.

Move them to the ssd130x core driver and just set the OF device entries to
an ID that could be used to lookup the correct device info from an array.

While being there, also move the SSD130X_DATA and SSD130X_COMMAND control
bytes. Since even though they are used by the I2C interface, they could
also be useful for other transport protocols such as SPI.

drm/ssd130x: Support page addressing mode
On the SINO WEALTH SH1106, which is mostly compatible with the SSD1306,
only the basic page addressing mode is supported. This addressing mode
is not as easy to use compared to the currently supported horizontal
addressing mode, as the page address has to be set prior to writing
out each page, and each page must be written out separately as a result.
Also, there is no way to force the column address to wrap around early,
thus the column address must also be reset for each page to be accurate.

Add support for this addressing mode, with a flag to choose it. This
flag is designed to be set from the device info data structure, but
can be extended to be explicitly forced on through a device tree
property if such a need arises.

drm/ssd130x: Fix rectangle updates
The rectangle update functions ssd130x_fb_blit_rect() and
ssd130x_update_rect() do not behave correctly when x1 != 0 or y1 !=
0, or when y1 or y2 are not aligned to display page boundaries.
E.g. when used as a text console, only the first line of text is shown
on the display.

  1. The buffer passed by ssd130x_fb_blit_rect() points to the first
     byte of monochrome bitmap data, and thus has its origin at (x1,
     y1), while ssd130x_update_rect() assumes it is at (0, 0).
     Fix ssd130x_update_rect() by changing the vertical and horizontal
     loop ranges, and adding the offsets only when needed.

  2. In ssd130x_fb_blit_rect(), align y1 and y2 to the display page
     boundaries before doing the color conversion, so the full page
     is converted and updated.
     Remove the correction for an unaligned y1 from
     ssd130x_update_rect(), and add a check to make sure y1 is aligned.

drm/format-helper: Rename drm_fb_xrgb8888_to_mono_reversed()
There is no "reversed" handling in drm_fb_xrgb8888_to_mono_reversed():
the function just converts from color to grayscale, and reduces the
number of grayscale levels from 256 to 2 (i.e. brightness 0-127 is
mapped to 0, 128-255 to 1).  All "reversed" handling is done in the
repaper driver, where this function originated.

Hence make this clear by renaming drm_fb_xrgb8888_to_mono_reversed() to
drm_fb_xrgb8888_to_mono(), and documenting the black/white pixel
mapping.
