Pass an instance of struct drm_format_conv_state to DRM's format
conversion helpers. Update all callers.
Most drivers can use the format-conversion state from their shadow-
plane state. The shadow plane's destroy function releases the
allocated buffer. Drivers will later be able to allocate a buffer
of appropriate size in their plane's atomic_check code.
The gud driver uses a separate thread for committing updates. For
now, the update worker contains its own format-conversion state.
Images in the format-helper tests are small. The tests preallocate
a static page for the temporary buffer. Unloading the module releases
the memory.

The Solomon SSD132x controllers (such as the SSD1322, SSD1325 and SSD1327)
are used by 16 grayscale dot matrix OLED panels, extend the driver to also
support this chip family.
Instead adding an indirection level to allow the same modesetting pipeline
to be used by both controller families, add another pipeline for SSD132x.
This leads to some code duplication but it makes the driver easier to read
and reason about. Once other controller families are added (e.g: SSD133x),
some common code can be factored out in driver helpers to be shared by the
different families. But that can be done later once these patterns emerge.

This deemed useful to avoid hardcoding a page height and allow to support
other Solomon controller families, but dividing the screen in pages seems
to be something that is specific to the SSD130x chip family.
For example, SSD132x chip family divides the screen in segments (columns)
and common outputs (rows), so the concept of screen pages does not exist
for the SSD132x family.
Let's drop this field from the device info struct and just use a constant
SSD130X_PAGE_HEIGHT macro to define the page height. While being there,
replace hardcoded 8 values in places where it is used as the page height.

The driver uses a naming convention where functions for struct drm_*_funcs
callbacks are named ssd130x_$object_$operation, while the callbacks for
struct drm_*_helper_funcs are named ssd130x_$object_helper_$operation.
The idea is that this helper_ prefix in the function names denote that are
for struct drm_*_helper_funcs callbacks. This convention was copied from
other drivers when ssd130x was written, but Maxime pointed out that is the
exception rather than the norm.
So let's get rid of the _helper prefixes from the function handlers names.

The commit 45b58669e5 ("drm/ssd130x: Allocate buffer in the plane's
.atomic_check() callback") moved the allocation of the intermediate and
HW buffers from the encoder's .atomic_enable callback, to the plane's
.atomic_check callback.
This was suggested by Maxime Ripard, because drivers aren't allowed to
fail after the drm_atomic_helper_swap_state() function has been called.
And the encoder's .atomic_enable happens after the new atomic state has
been swapped, so allocations (that can fail) shouldn't be done there.
But the HW buffer isn't really tied to the plane's state. It has a fixed
size that only depends on the (also fixed) display resolution defined in
the Device Tree Blob.
That buffer can be considered part of the CRTC state, and for this reason
makes more sense to do its allocation in the CRTC .atomic_check callback.
The other allocated buffer (used to store a conversion from the emulated
XR24 format to the native R1 format) is part of the plane's state, since
it will be optional once the driver supports R1 and allows user-space to
set that pixel format.
So let's keep the allocation for it in the plane's .atomic_check callback,
this can't be moved to the CRTC's .atomic_check because changing a format
does not trigger a CRTC mode set.

Due to the reuse of buffers, ssd130x_clear_screen() no longers clears

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.

The commit 45b58669e5 ("drm/ssd130x: Allocate buffer in the plane's

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.

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.

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.

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.

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 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.
