* drm/i915: move quirks under display sub-structJani Nikula2022-08-311-2/+2
| | | | | | | | | | | | Move display quirk related members under drm_i915_private display sub-struct. Prefer adding anonymous sub-structs even for single members that aren't our own structs.

* drm/i915/quirks: abstract quirks further by making quirk ids an enumJani Nikula2022-08-311-8/+13
| | | | | | | | | | Turn the quirk ids to enums instead of bits, and hide the masking inside intel_quirks.c. Define the enums in intel_quirks.h to declutter i915_drv.h while at it.

* drm/i915/glk: ECS Liva Q2 needs GLK HDMI port timing quirkDiego Santa Cruz2022-08-251-0/+3
| | | | | | | | | | | | | | | | The quirk added in upstream commit 90c3e2198777 ("drm/i915/glk: Add Quirk for GLK NUC HDMI port issues.") is also required on the ECS Liva Q2. Note: Would be nicer to figure out the extra delay required for the retimer without quirks, however don't know how to check for that.

* drm/i915: keep backlight_enable on until turn eDP display offLee Shawn C2021-06-241-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This workaround is specific for a particular panel on Google chromebook project. When user space daemon enter idle state. It request adjust brightness to 0, turn backlight_enable signal off and keep eDP main link active. On general LCD, this behavior might not be a problem. But on this panel, its tcon would expect source to execute full eDP power off sequence after drop backlight_enable signal. Without eDP power off sequence. Even source try to turn backlight_enable signal on and restore proper brightness level. This panel is not able to light on again. This WA ignored the request from user space daemon to disable backlight_enable signal and keep it on always. When user space request kernel to turn eDP display off, kernel driver still can control backlight_enable signal properly. It would not impact standard eDP power off sequence. v2: 1. modify the quirk name and debug messages. 2. unregister backlight.power callback for specific device. v3: 1. modify debug output messages. 2. use DMI_EXACT_MATCH instead of DMI_MATCH.

* drm/i915: Add invert-brightness quirk for Thundersoft TST178 tabletHans de Goede2020-03-041-0/+10
| | | | | | | | | | | | | | | | | | The Thundersoft TST178 tablet uses a DSI panel with an external PWM controller (as all DSI panels do). But unlike other DSI panels a duty-cycle of 100% turns the backlight off and 0% sets it to maximum brightness. I've checked the VBT and there is a BDB_LVDS_BACKLIGHT section, but it does not set the active_low_pwm flag. This tablet re-uses the main PCI vendor and product ids for the subsystem ids, so I see no other option then to add a DMI based quirk to fix this. Note that the PWM backlight code in intel_panel.c currently does not honor the vbt.active_low_pwm flag, but that does not matter in this case.
