Merge branch 'tda998x-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-cubox into drm-next

Updates from Jean-Fracois for the TDA998x driver, which are on top of
the fixes you have previously pulled, except these changes aren't
intended for -rc, but the next merge window.

Several of these are issues of correctness - passing more correct HDMI
info packets, not reading registers in older chips documented as write
only (despite appearing to be read/write in later chips).  Others are
code cleanups (using definitions rather than constants where we have
them already in the kernel).

Additional functionality is also added by way of optional support for
the IRQ from the TDA998x, which allows us to avoid busy-waiting for
the EDID reads.
