[PATCH 0/9] video: rockchip: VOP2 and HDMI output for RK3568

[Daniel Golle <daniel@makrotopia.org>]

U-Boot has no video output support for the RK3568/RK3566 family: the
VOP2 display controller found in these SoCs (and newer Rockchip parts)
is unsupported, so boards cannot show a boot menu, the UEFI console or
any other firmware user interface on a locally attached display, while
the vendor firmware and the Linux kernel have long been able to drive
it.

This series brings up HDMI output on RK3568 in U-Boot proper so that a
plain monitor plus USB keyboard is enough to interact with the
firmware, using the NanoPi R5C as the reference board.

The VOP2 driver and the RK3568 HDMI glue were written by Dang Huynh,
modelled on the existing VOP support and the Linux driver. On top of
that, bring-up on real hardware showed that U-Boot must not rely on the
state left behind by earlier boot stages: the probe path is fixed to
map the right register base, and the HDMI controller clocks, the PHY
reference clock and the PHY analog supplies are now enabled explicitly
by the driver instead of assuming the BootROM, TPL or a previous
firmware left them on. The final patch enables video output on the
NanoPi R5C.
