Changes in v7:
- Take in account invalid bit_count
- Write bit_count back if clamped within BIT_COUNT_CAP_MIN & BIT_COUNT_CAP_MAX
- Link to v6: https://lore.kernel.org/all/20250330-wip-obbardc-qcom-t14s-oled-panel-brightness-v6-1-84ad1cd1078a@linaro.org
Changes in v6:
- Update commit message around chaning reading PWMGEN_BIT_COUNT_CAP_MIN
and _CAP_MAX to be required.
- Link to v5: https://lore.kernel.org/r/20250330-wip-obbardc-qcom-t14s-oled-panel-brightness-v5-1-25083d9732fc@linaro.org
Changes in v5:
- Correctly check return value when reading PWMGEN_BIT_COUNT_CAP_MIN
and _CAP_MAX.
- Link to v4: https://lore.kernel.org/r/20250330-wip-obbardc-qcom-t14s-oled-panel-brightness-v4-1-85ef0991bdf8@linaro.org
Changes in v4:
- Remove unrelated whitespace changes.
- Remove unrelated commit change.
- Add note to commit message about changing read of PWMGEN_BIT_COUNT_CAP_MIN
and _CAP__MAX from optional to required.
- Link to v3: https://lore.kernel.org/r/20250330-wip-obbardc-qcom-t14s-oled-panel-brightness-v3-1-156801d97a8a@linaro.org
Changes in v3:
- Properly rebase patch on top of latest version of drm-misc-next.
- Make patch more generic by clamping PWM bit count to advertised MIN
and MAX capabilities (suggested by Dmitry).
- Link to v2: https://lore.kernel.org/r/20250327-wip-obbardc-qcom-t14s-oled-panel-brightness-v2-1-16dc3ee00276@linaro.org
Changes in v2:
- Split backlight brightness patch from T14s OLED enablement series.
- Use PWMGEN_CAP_MIN rather than MAX (Dmitry).
- Rework commit message to reference eDP spec.
- Rebase on drm-misc-next.
- Link to v1: https://lore.kernel.org/all/20250325-wip-obbardc-qcom-t14s-oled-panel-v2-4-e9bc7c9d30cc@linaro.org/
