This series fixes several issues found in R40 HDMI patch series after it was applied. Conversation can be found here: http://lists.infradead.org/pipermail/linux-arm-kernel/2018-June/586011.html
One issue raised in that thread is probably not solved (conversation still on going), but I want to send these patches for review before I'm going on vacation.
There is also additional DW HDMI driver fix not mentioned in mails.
Patches are based on latest linux-next (next-20180706) and are ordered in such way that they don't break R40 HDMI at any time. Because of that I suggest that whole series goes through drm-misc to preserve that order.
I also tested those patches on H3 to make sure it doesn't break other platforms. However, it would be nice to test for regressions also on older SoCs (with DE1).
Best regards, Jernej
