This patchset include a couple of different things - all related to panels. - The callbacks are optional - so drop error if callback is not present. - Add support for backlight in drm_panel. This allows us to make much simpler backlight support to most panels. The patchset include conversion of most of the trivial cases. - Drop drm_connector from drm_panel. This change required many changes to most panels and many bridges and display drivers. This is by far the most invasive change in this patchset. With this patchset drm_panel_(attach|detach) are nop's but they are kept for now. A few of these patches has been sent out before - but versioning started again from v1 - as the most patches are new. I have tested the panel-simple changes, and thus some of the infrastructure changes. The testing was done on an earlier iteration - and I ended up submitting this as Laurent and others started to depend on it. v2: This is mostly addressing comments from Laurent. - drop get_timings removal, we should start using it - do not fail in drm_panel_of_backlight() if DT is not enabled - updated changelogs and code comments in many places (thanks Laurent!) - get_modes is a mandatory callback - return -EOPNOTSUPP if not specified - log if backlight update fails - added a-b/r-bs o thanks to Laurent and Linus for the prompt reviews! When "drm/panel: add backlight support" is reviewed I plan to apply the full series to drm-misc-next.
