[PATCH v2] drm/i915/quirk: Add quirk for devices with incorrect PWM frequency

2023-11-10 Thread Allen Ballway
Cyernet T10C has a bad default PWM frequency causing the display to strobe when the brightness is less than 100%. Create a new quirk to use the value from the BIOS rather than the default register value. Signed-off-by: Allen Ballway --- V1 -> V2: Fix style issues. .../gpu/drm/i915/disp

[PATCH v3 RESEND] drm/i915/quirk: Add quirk for devices that cannot be dimmed

Cybernet T10C cannot be dimmed without the backlight strobing. Create a new quirk to lock the minimum brightness to the highest supported value. This aligns the device with its behavior on Windows, which will not lower the brightness below maximum. Signed-off-by: Allen Ballway --- V2 -> V3:
