Linux 6.18-rc6

Align pitch to multiples of 8 pixels for bpp values that do not map
to RGB formats. The call to drm_driver_color_mode_format() fails with
DRM_INVALID_FORMAT in these cases. Fall back to manually computing
the pitch alignment from which drm_mode_size_dumb() can compute the
correct pitch.
Fixes userspace that allocates dumb buffers for YUV formats, where
bpp equals 12. A common example is the IGT kms_getfb test.

This is the new API for allocating DRM bridges.
This conversion was missed during the initial conversion of all bridges to
the new API. Thus all kernels with commit 94d50c1a2ca3 ("drm/bridge:
get/put the bridge reference in drm_bridge_attach/detach()") and using this
driver now warn due to drm_bridge_attach() incrementing the refcount, which
is not initialized without using devm_drm_bridge_alloc() for allocation.
To make the conversion simple and straightforward without messing up with
the drmm_simple_encoder_alloc(), move the struct drm_bridge from struct
imx_parallel_display_encoder to struct imx_parallel_display.
Also remove the 'struct imx_parallel_display *pd' from struct
imx_parallel_display_encoder, not needed anymore.

Call drm_mode_size_dumb() to compute dumb-buffer scanline pitch and
buffer size. The hardware requires the framebuffer width to be a
multiple of 8. The scanline pitch has to be large enough to support
this. Therefore compute the byte size of 8 pixels in the given color
mode and align the pitch accordingly.

Call drm_mode_size_dumb() to compute dumb-buffer scanline pitch and
buffer size. Align the pitch to a multiple of 8.
Push the current calculation into the only direct caller imx. Imx's
hardware requires the framebuffer width to be aligned to 8. The
driver's current approach is actually incorrect, as it only guarantees
this implicitly and requires bpp to be a multiple of 8 already. A
later commit will fix this problem by aligning the scanline pitch
such that an aligned width still fits into each scanline's memory.
A number of other drivers are build on top of gem-dma helpers and
implement their own dumb-buffer allocation. These drivers invoke
drm_gem_dma_dumb_create_internal(), which is not affected by this
commit.

i.MX8qxp Display Controller(DC) is comprised of three main components that
include a blit engine for 2D graphics accelerations, display controller for
display output processing, as well as a command sequencer. Add kernel
mode setting support for the display controller part with two CRTCs and
two primary planes(backed by FetchLayer and FetchWarp respectively). The
registers of the display controller are accessed without command sequencer
involved, instead just by using CPU. The command sequencer is supposed to
be used by the blit engine.

The drm_bridge structure contains an encoder pointer that is widely used
by bridge drivers. This pattern is largely documented as deprecated in
other KMS entities for atomic drivers.
However, one of the main use of that pointer is done in attach to just
call drm_bridge_attach on the next bridge to add it to the bridge list.
While this dereferences the bridge->encoder pointer, it's effectively
the same encoder the bridge was being attached to.
We can make it more explicit by adding the encoder the bridge is
attached to to the list of attach parameters. This also removes the need
to dereference bridge->encoder in most drivers.

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.

disable_irq() after request_irq() still has a time gap in which

disable IRQ auto-enable when request IRQ.

drm_bridge_connector is a "leaf" driver, belonging to the display
helper, rather than the "CRTC" drm_kms_helper module. Move the driver
to the drm/display and add necessary Kconfig selection clauses.

Use the imx_legacy bridge driver instead of handlign display modes via
the connector node.
All existing usecases already support attaching using
the DRM_BRIDGE_ATTACH_NO_CONNECTOR flag, while the imx_legacy bridge
doesn't support creating connector at all. Switch to
drm_bridge_connector at the same time.

None of the boards ever supported by the upstream kernel used the custom
DDC bus support with the LDB connector. If a need arises to do so, one
should use panel-simple and its DDC bus code. Drop ddc-i2c-bus support
from the imx-ldb driver.

None of the in-kernel DT files ever used edid override with the
fsl-imx-drm driver. In case the EDID needs to be specified manually, DRM
core allows one to either override it via the debugfs or to load it via
request_firmware by using DRM_LOAD_EDID_FIRMWARE. In all other cases
EDID and/or modes are to be provided as a part of the panel driver.
Drop support for the edid property.
