Clock rate check that was added in commit bb43d40d7c83 ("drm/sun4i: rgb:
Validate the clock rate") prevents some panel and bridges from working with
sun4i driver.
Unfortunately, dotclock frequency for some modes are not achievable on
sunxi hardware, and there's a slight deviation in rate returned

Some definitions currently in analogix-anx78xx.h are not restricted to
the ANX78xx series, but also applicable to other DisplayPort
transmitters by Analogix.
Split out them to dedicated headers, and make analogix-anx78xx.h include
them.

eDP panels usually have EDID EEPROM, so there's no need to define panel
width/height or any modes/timings in dts. But this panel still has
regulator and backlight.
Add compatible for generic eDP panel so such kind of panel can be
defined in dts.

Hi everyone,
Since the HS-DDR mode was enabled for the A64 eMMC controller, there

that while the H5 and A64 share the same controller for eMMC, some H5
boards don't have trace lengths that work under HS-DDR with the default

its eMMC run at HS-DDR speed mode. Mark it as such.

Some H5 boards seem to not have proper trace lengths for eMMC to be able
to use the default setting for the delay chains under HS-DDR mode. These
include the Bananapi M2+ H5 and NanoPi NEO Core2. However the Libre
Computer ALL-H3-CC-H5 works just fine.
For the H5 (at least for now), default to
The MMC device tree bindings include properties used to signal various
signalling speed modes. Until now the sunxi driver was accepting them
without any further filtering, while the sunxi device trees were not
actually using them.
