Implement DisplayPort support for the Qualcomm RB5 platform.
Note: while testing this, I had link training issues with several
dongles with DP connectors. Other DisplayPort-USB-C dongles (with HDMI
or VGA connectors) work perfectly.
Dependencies: [1]
Soft-dependencies: [2], [3]

It looks like DP controlled on SM8250 is the same as DP controller on
SM8350. Use the SM8350 compatible as fallback for SM8250.

this is used to deliver "attention" messages to the DP host. Stop

In some implementations, such as the Qualcomm platforms, the display
driver has no way to query the current HPD state and as such it's
impossible to distinguish between disconnect and attention events.
Add a parameter to drm_connector_oob_hotplug_event() to pass the HPD
Note, this is sent as v5, since there were several revisions for this
patchset under a different series title ([1]).
USB altmodes code would send OOB notifications to the drm_connector
specified in the device tree. However as the MSM DP driver uses
drm_bridge_connector, there is no way to receive

Support a 1D gamma LUT with interpolation for each color channel on the

vkms_atomic_check().
Enable VKMS to run the test igt@kms_plane@pixel-format.

Both struct dpu_dsc_sub_blks instances declare enc subblock length to be

The previous values were completely bogus, and resulted in the computed
DPI ratio being much lower than reality, causing applications and UIs to
misbehave.
The new values were measured by myself with a ruler.

The devm_clk_get_enabled() helper:
- calls devm_clk_get()
- calls clk_prepare_enable() and registers what is needed in order to
call clk_disable_unprepare() when needed, as a managed resource.
This simplifies the code and avoids the need of a dedicated function used
