6a8a58acfe drm/imx/dcss: fix compilation issue on 32bit
When compiling for 32bit platforms, the compilation fails with:

ERROR: modpost: "__aeabi_ldivmod"

ERROR: modpost: "__aeabi_uldivmod"

This patch adds a dependency on ARM64 since no 32bit SoCs have DCSS, so far.

9021c317b7 drm/imx: Add initial support for DCSS on iMX8MQ
This adds initial support for iMX8MQ's Display Controller Subsystem (DCSS).
Some of its capabilities include:
 * 4K@60fps;
 * HDR10;
 * one graphics and 2 video pipelines;
 * on-the-fly decompression of compressed video and graphics;

The reference manual can be found here:
https://www.nxp.com/webapp/Download?colCode=IMX8MDQLQRM

The current patch adds only basic functionality: one primary plane for
graphics, linear, tiled and super-tiled buffers support (no graphics
decompression yet), no HDR10 and no video planes.

Video planes support and HDR10 will be added in subsequent patches once
per-plane de-gamma/CSC/gamma support is in.

dbd1d67d92 drm/imx: parallel-display: Adjust bus_flags handling
The bus_flags handling logic does not seem to cover all potential
usecases. Specifically, this seems to fail with an "edt,etm0700g0edh6"
display attached to an 24bit display interface, with interface-pix-fmt
= "rgb24" set in DT.

This patch fixes the problem by overriding the imx_crtc_state->bus_flags
from the imxpd->bus_flags only if the DT property "interface-pix-fmt" is
present or if the DI provides no formats.

ba807c94f6 drm/imx: fix use after free
Component driver structures allocated with devm_kmalloc() in bind() are
freed automatically after unbind(). Since the contained drm structures
are accessed afterwards in drm_mode_config_cleanup(), move the
allocation into probe() to extend the driver structure's lifetime to the
lifetime of the device. This should eventually be changed to use drm
resource managed allocations with lifetime of the drm device.

We also need to ensure that all componets are available during the
unbind() so we need to call component_unbind_all() before we free
non-devres resources like planes.

Note this patch fixes the the use after free bug but introduces a
possible boot loop issue. The issue is triggered if the HDMI support is
enabled and a component driver always return -EPROBE_DEFER, see
discussion [1] for more details.

a25b988ff8 drm/bridge: Extend bridge API to disable connector creation
Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:

- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.

- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.

- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).

In order to solve these issues, ownership of the connector should be
moved to the display controller driver (where it can be implemented
using helpers provided by the core).

Extend the bridge API to allow disabling connector creation in bridge
drivers as a first step towards the new model. The new flags argument to
the bridge .attach() operation allows instructing the bridge driver to
skip creating a connector. Unconditionally set the new flags argument to
0 for now to keep the existing behaviour, and modify all existing bridge
drivers to return an error when connector creation is not requested as
they don't support this feature yet.

The change is based on the following semantic patch, with manual review
and edits.

fe141cedc4 drm/imx: pd: Use bus format/flags provided by the bridge when available
Now that bridges can expose the bus format/flags they expect, we can
use those instead of the relying on the display_info provided by the
connector (which is only valid if the encoder is directly connected
to bridge element driving the panel/display).

We also explicitly expose the bus formats supported by our encoder by
filling encoder->output_bus_caps with proper info.

v10:
* Add changelog to the commit message
* Use kmalloc() instead of kcalloc()
* Add a dev_warn() when unsupported flags are requested

v8 -> v9:
* No changes

v7:
* Add an imx_pd_format_supported() helper (suggested by Philipp)
* Simplify imx_pd_bridge_atomic_get_output_bus_fmts() (suggested by Philipp)
* Simplify imx_pd_bridge_atomic_get_input_bus_fmts()
* Explicitly set the duplicate/destro_state() and reset() hooks

v4 -> v6:

v3 (all suggested by Philipp):
* Adjust to match core changes
* Propagate output format to input format
* Pick a default value when output_fmt = _FIXED
* Add missing BGR888 and GBR888 fmts to imx_pd_bus_fmts[]

06c4a9c2ae drm/panel: decouple connector from drm_panel
To facilitate moving connector creation to display drivers,
decouple the drm_connector from drm_panel.

This patch adds a connector argument to drm_panel_get_modes().

All users of drm_panel_get_modes() already had the connector
available, so updating users was trivial.

With this patch drm_panel no longer keeps a reference to the drm_connector.

ee68c743f8 drm: Stop including drm_bridge.h from drm_crtc.h
We are about to add a drm_bridge_state that inherits from
drm_private_state which is defined in drm_atomic.h. Problem is,
drm_atomic.h includes drm_crtc.h which in turn includes drm_bridge.h,
leading to "drm_private_state has incomplete type" error.

Let's force all users of the drm_bridge API to explicitly include
drm_bridge.h.

5aeab2bfc9 drm/imx: only send event on crtc disable if kept disabled
The event will be sent as part of the vblank enable during the modeset
if the crtc is not being kept disabled.

78c68e8f5c drm/imx: notify drm core before sending event during crtc disable
Notify drm core before sending pending events during crtc disable.
This fixes the first event after disable having an old stale timestamp
by having drm_crtc_vblank_off update the timestamp to now.

This was seen while debugging weston log message:
Warning: computed repaint delay is insane: -8212 msec

This occurred due to:
1. driver starts up
2. fbcon comes along and restores fbdev, enabling vblank
3. vblank_disable_fn fires via timer disabling vblank, keeping vblank
seq number and time set at current value
(some time later)
4. weston starts and does a modeset
5. atomic commit disables crtc while it does the modeset
6. ipu_crtc_atomic_disable sends vblank with old seq number and time

0424fdaf88 drm/prime: Actually remove DRIVER_PRIME everywhere
Split out to make the functional changes stick out more.

All places where DRIVER_PRIME was used have been removed in previous
patches already.

v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE.

v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE.

v4: Don't add a space in i915_drv.c (Sam)

v5: Add note that previous patches removed all the DRIVER_PRIME users
already (Emil).

v6: Fixupe ingenic (new driver) while applying.
