This patch set contain 3 patches which are already reviewed by DK.
Another 6 patches in previous version was already merged in v7 and v9.
- First patch sets the PWM freqency to match data in panel vbt.
- Next patch adds heuristic to determine whether we should use AUX
or PWM pin to adjust panel backlight brightness.
- Last patch adds support for dynamic brightness.
Change log:
v11:
- Reorder patches in v10 to make the last patch come first
- Fix nits
v10:
- Add heuristic in patch #1
- Add _unsafe mod option in patch #1, #2
- handle frequency set error in patch #3
v9:
- Fix nits in v8
v8:
- Drop 4 patches that was already merged
- Move DP_EDP_BACKLIGHT_AUX_ENABLE_CAP check to patch #2 to avoid
behavior change if only apply patch #1
- Add TODO to warn about enable backlight twice in patch #2
- Use DIV_ROUND_CLOSEST instead of just "/" in patch #5
- Fix bug calculate pn in patch #5
- Clarify commit message / code comment in patch #5
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
