Note 1:
The DE clock is not set in the driver. Instead, it is set at system
startup time by 'assigned-clocks', but there is a problem in sunxi-ng
which uses readl_relaxed_poll_timeout(), and, as noticed by
Ondřej Jirman, this function is not available at startup time.
The fix of this problem is not part of this patchset series.
Note 2:
The DE clock is set to a high enough rate (432MHz). It seems that
this is needed to handle 4K video.
But, as the proposed DE driver does not treat yet 4K video, the clock
could be set to a lower rate. For example, the default rate for the A83T
is 250MHz (no 4K video).
