This series adds support for ARM's HDLCD display controller found in Juno
and ARM TC2 Coretile. The HDLCD outputs an RGB stream that feeds into a
single digital encoder (DVI or HDMI).
The dependencies for this patch series are now queued for the next release or
are already in the mainline.
Only the Juno functionality has been tested as the TC2 Coretile require
a working SiI9022 driver for VExpress that is not subject of this patchset.
Changelog:
v5: Queue the pending vblank events sent by userspace using a list instead of
keeping the last event seen. Suggested by Daniel Stone <daniel@xxxxxxxxxxxxx>.
v4: Remove some debugging code that could return an error on a critical path
and updated the check for valid format in hdlcd_set_pxl_fmt() to only
WARN() if an invalid format found (unlikely case). Added the ACKs received. [1]
v3: Changed the driver to use the memory-region phandle for bespoke framebuffers. [2]
v2: Added support for atomic modeset [3]
v1: Original DRM submission [4]
