This patch series converts the i915 driver's code for controlling the panel's backlight with an external PWM controller to use the atomic PWM API. Initially the plan was for this series to consist of 2 parts: 1. convert the pwm-crc driver to support the atomic PWM API and 2. convert the i915 driver's PWM code to use the atomic PWM API. But during testing I've found a number of bugs in the pwm-lpss and I found that the acpi_lpss code needs some special handling because of some ugliness found in most Cherry Trail DSDTs. So now this series has grown somewhat large and consists of 4 parts: 1. acpi_lpss fixes workarounds for Cherry Trail DSTD nastiness 2. various fixes to the pwm-lpss driver 3. convert the pwm-crc driver to support the atomic PWM API and 4. convert the i915 driver's PWM code to use the atomic PWM API So we need to discuss how to merge this (once it passes review). Although the inter-dependencies are only runtime I still think we should make sure that 1-3 are in the drm-intel-next-queued (dinq) tree before merging the i915 changes. Both to make sure that the intel-gfx CI system does not become unhappy and for bisecting reasons. The involved acpi_lpss and pwm drivers do not see a whole lot of churn, so we could just merge everything through dinq, or we could use immutable branch and merge those into dinq. So Rafael and Thierry, can I either get your Acked-by for directly merging this into dinq, or can you provide an immutable branch with these patches? This series has been tested (and re-tested after adding various bug-fixes) extensively. It has been tested on the following devices: -Asus T100TA BYT + CRC-PMIC PWM -Toshiba WT8-A BYT + CRC-PMIC PWM -Thundersoft TS178 BYT + CRC-PMIC PWM, inverse PWM -Asus T100HA CHT + CRC-PMIC PWM -Terra Pad 1061 BYT + LPSS PWM -Trekstor Twin 10.1 BYT + LPSS PWM -Asus T101HA CHT + CRC-PMIC PWM -GPD Pocket CHT + CRC-PMIC PWM Regards, Hans _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
