Change log: v2: - Drop PWM frequency patch - Addess suggestion from Jani Nikula v3: - Add new implementation of PWM frequency patch v4: - Rebase / minor typo fix. v5: - Split first patch in v4 to 3 patches - Bump priority for "Correctly enable backlight brightness adjustment via DPCD" - Make logic clearer for the case that both PWM pin and AUX are supported - Add more log when write to register fail - Add log when enable DBC Puthikorn Voravootivat (9): drm/i915: Fix cap check for intel_dp_aux_backlight driver drm/i915: Correctly enable backlight brightness adjustment via DPCD drm/i915: Drop AUX backlight enable check for backlight control drm/i915: Allow choosing how to adjust brightness if both supported drm/i915: Set backlight mode before enable backlight drm/i915: Support dynamic backlight via DPCD register drm/i915: Restore brightness level in aux backlight driver drm: Add definition for eDP backlight frequency drm/i915: Set PWM divider to match desired frequency in vbt drivers/gpu/drm/i915/i915_params.c | 6 +- drivers/gpu/drm/i915/i915_params.h | 2 +- drivers/gpu/drm/i915/intel_dp_aux_backlight.c | 161 ++++++++++++++++++++++++-- include/drm/drm_dp_helper.h | 2 + 4 files changed, 156 insertions(+), 15 deletions(-) -- 2.13.0.rc1.294.g07d810a77f-goog _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
