<content type='text'>
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.

Allocated canvases may not be released on the error exit path of
meson_drv_bind_master(), leading to resource leaking. Rewrite exit path
to release canvases on error.

This patch adds robust error handling to the meson_plane_create
function in drivers/gpu/drm/meson/meson_plane.c. The function
previously lacked proper handling for potential failure scenarios
of the drm_universal_plane_init call.

Pull drm updates from Dave Airlie:
 "This is the main pull request for the drm subsystems for 6.10.

  In drivers the main thing is a new driver for ARM Mali firmware based
  GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and
  scattered changes to everything else.

  In the core a bunch of headers and Kconfig was refactored, along with
  the addition of a new panic handler which is meant to provide a user
  friendly message when a panic happens and graphical display is
  enabled.

<content type='text'>
When no mode is set, the utility pin appears to be grounded. No signal
is getting through.

This is problematic because ARC and eARC use this line and may do so even
if no display mode is set.

This change enable the bandgap setting on g12 chip, which fix the problem
with the utility pin. This is done by restoring init values on PHY init and
disable.

The phy is not in a useful state right after init. It will become useful,
including for auxiliary function such as CEC or ARC, after the first mode
is set. This is a problem on systems where the display is using another
interface like DSI or CVBS.

This change refactor the init and mode change callback to power up the PHY
on init and leave only what is necessary for mode changes in the related
function. This is enough to fix CEC operation when HDMI display is not
enabled.

This reverts commit c0e0f139354c01e0213204e4a96e7076e5a3e396, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.

The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in.  Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.

Disable the px_clk when setting the rate to recover a fully
configured and correctly reset VCLK clock tree after the rate
is set.

<title>drm/meson: vclk: fix calculation of 59.94 fractional rates</title>

Playing 4K media with 59.94 fractional rate (typically VP9) causes the screen to lose
sync with the following error reported in the system log:

[   89.610280] Fatal Error, invalid HDMI vclk freq 593406

Modetest shows the following:

3840x2160 59.94 3840 4016 4104 4400 2160 2168 2178 2250 593407 flags: xxxx, xxxx,
drm calculated value -------------------------------------^

Change the fractional rate calculation to stop DIV_ROUND_CLOSEST rounding down which
results in vclk freq failing to match correctly.
