Subject: [PATCH v3 0/9] drm/i915: Add support for Intel's eDP backlight controls
Date: Fri, 4 Dec 2020 17:35:54 -0500 [thread overview]
Message-ID: <20201204223603.249878-1-lyude@redhat.com> (raw)
A while ago we ran into issues while trying to enable the eDP backlight
control interface as defined by VESA, in order to make the DPCD
backlight controls on newer laptop panels work. The issue ended up being
much more complicated however, as we also apparently needed to add
support for an Intel-specific DPCD backlight control interface as the
VESA interface is broken on many laptop panels. For lack of a better
name, we just call this the Intel HDR backlight interface.
While this only adds support for the SDR backlight mode (I think), this
will fix a lot of user's laptop panels that we weren't able to properly
automatically detect DPCD backlight controls on previously.
Series-wide changes in v3:
* Pass down brightness values to enable/disable backlight callbacks in a
separate patch
* Rebase
Lyude Paul (9):
drm/i915/dp: Program source OUI on eDP panels
drm/i915: Rename pwm_* backlight callbacks to ext_pwm_*
drm/i915: Pass down brightness values to enable/disable backlight
callbacks
drm/i915: Keep track of pwm-related backlight hooks separately
drm/i915/dp: Rename eDP VESA backlight interface functions
drm/i915/dp: Add register definitions for Intel HDR backlight
interface
drm/i915/dp: Enable Intel's HDR backlight interface (only SDR for now)
drm/i915/dp: Allow forcing specific interfaces through
enable_dpcd_backlight
drm/dp: Revert "drm/dp: Introduce EDID-based quirks"
