Since the current MAINTAINERS include the whole drm/arm folder, one
could just generalise the heading alike

s/ARM HDLCD DRM DRIVER/ARM DRM DRIVERS/

... and fold the bindings in a similar fashion (or just update to
include the new one)

git mv Documentation/devicetree/bindings/display/arm{\,,/}foo.txt

For the Mali DP drivers we are planning to have a shared maintainership
as it is covering quite a few HW versions and is a more complex driver.
HDLCD is a very simple driver (and hardware part) so I'm going to keep
that maintainership on my name, but the rest of Mali DP will have a wider
support team.

It is the reason why the patchset does not have a MAINTAINERS update.

Best regards,
Liviu
