The KMS framework uses two slightly different definitions for the state
concept. For a given object (plane, CRTC, encoder, etc., so
drm_$OBJECT_state), the state is the entire state of that object.
However, at the device level, drm_atomic_state refers to a state update
for a limited number of objects.
Thus, drm_atomic_state isn't the entire device state, but only the full
state of some objects in that device. This has been an endless source of
confusion and thus bugs.
We can rename the drm_atomic_state structure to drm_atomic_commit to
make it less confusing.
This patch was created using:
rg -l drm_atomic_state | \

shmob_drm_connector_create() can init the connector in two ways, based on
the 'if (sdev->pdata)':
1. manually in shmob_drm_connector_create(), or
2. delegating to drm_bridge_connector_init()
Whichever branch is taken, drm_connector_attach_encoder() is called
immediately after to attach the connector to the encoder.
Now drm_bridge_connector_init() calls drm_connector_attach_encoder() on the
connector so it is not needed anymore in case 2 and should be removed, but
it is still needed in case 1. Move drm_connector_attach_encoder() from the
common path to inside shmob_drm_connector_create() in order to get back to
a single drm_connector_attach_encoder() in both cases.

This was done entirely with mindless brute force, using

xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

This is the result of running the Coccinelle script from

avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

Based on grepping through the source code, this driver appears to be
missing a call to drm_atomic_helper_shutdown() at system shutdown time.
This is important because drm_atomic_helper_shutdown() will cause
panels to get disabled cleanly which may be important for their power
sequencing. Future changes will remove any custom powering off in
individual panel drivers so the DRM drivers need to start getting this
right.
The fact that we should call drm_atomic_helper_shutdown() in the case of
OS shutdown comes straight out of the kernel doc "driver instance
overview" in drm_drv.c.

The DRM core vblank handling mechanism requires drivers to forcefully
turn vblank reporting off when disabling the CRTC, and to restore the
vblank reporting status when enabling the CRTC.
Implement this using the drm_crtc_vblank_{on,off}() helpers.
Note that drm_crtc_vblank_off() must be called at startup to synchronize
the state of the vblank core code with the hardware, which is initially
disabled. This is performed at CRTC creation time, requiring vertical
blank initialization to be moved before creating CRTCs.

Backlight support should be implemented by panels, not by the LCDC
driver. As the feature is currently unused anyway, remove it.

Improve the table containing hardware information related to the
supported plane formats:
1. Move (part of) the overlay format register settings from multiple
switch() statements spread across the code into the table, like is
already done for the primary plane register settings,
2. Remove the .yuv field, as that information can easily be extracted
from the register settings using a new helper macro,
3. Shrink and move the .bpp field to reduce table size.

The primary plane supports various YCbCr formats, and the CRTC code
already knows how to handle them. Enable support for the missing
formats by adding them to the table of supported modes.
