This patch set contain 9 patches. - First five patches fix bug in the driver and allow choosing which way to adjust brightness if both PWM pin and AUX are supported - Next patch adds enable DBC by default - Next patch makes the driver restore last brightness level after turning display off and on. - Last two patches set the PWM freqency to match data in panel vbt. This patch set is reviewed by Dhinakaran in patch #1, 2, 5, 7, 8 Change log: v7: - Add check in intel_dp_pwm_pin_display_control_capable in patch #4 - Add option in patch #6 to enable DPCD or not - Change definition in patch #8 and implementation in #9 to use Khz - Fix compiler warning from build bot in patch #9 v6: - Address review from Dhinakaran - Make PWM frequency to have highest value of Pn that make the frequency still within 25% of desired frequency. 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 v4: - Rebase / minor typo fix. v3: - Add new implementation of PWM frequency patch v2: - Drop PWM frequency patch - Address suggestion from Jani Nikula 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: Add option to support dynamic backlight via DPCD 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 | 13 +- drivers/gpu/drm/i915/i915_params.h | 5 +- drivers/gpu/drm/i915/intel_dp_aux_backlight.c | 173 ++++++++++++++++++++++++-- include/drm/drm_dp_helper.h | 2 + 4 files changed, 176 insertions(+), 17 deletions(-) -- 2.13.0.rc2.291.g57267f2277-goog _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
