Hi All,
I will be at Plumbers Dublin next week and I was wondering if
anyone interested in this wants to get together for a quick
discussion / birds of a feather session about this?
I have just posted version 2 of the RFC:
Hi all,
Here is v2 of my "drm/kms: control display brightness through drm_connector
properties" RFC:
Changes from version 1:
- Drop bl_brightness_0_is_min_brightness from list of new connector
properties.
- Clearly define that 0 is always min-brightness when setting the brightness
through

When acpi_video_register() has not run yet the video_bus_head will be
empty, so there is no need to check the register_count flag first.

Relying on the cached native_available value not only is simpler, it will
also work correctly in cases where then native backlight registration was
skipped because of acpi_video_backlight_use_native() returning false.
