[U-Boot] [PATCH v2 0/5] rockchip: video: rk3399: enable HDMI output

[Philipp Tomsich]

This series provides HDMI enablement for the RK3399 and will support
video console on the RK3399 either with VOP-lit or VOP-big:
 - pinctrl and clk support for the hdmi node
 - a refactoring of rk_vop.c and rk_hdmi.c to allow for the minor
   differences between the RK3288 and RK3399 VOP and HDMI blocks

To see the full series in the context of a working configuration (i.e.
including DTS, defconfig, etc. and on top of the MIPI enablement
change series from Rockchip), refer to
       https://git.theobroma-systems.com/puma-u-boot.git/log/?h=puma-hdmi-rfc

This has been tested (on top of Eric Gao's change series for MIPI-DSI)
using 'bmp display' and 'setenv stdout vidconsole' on the RK3399-Q7
with various HDMI monitors, both for VOP-lit and VOP-big (setting the
other one to 'disabled').

Changes in v2:
- removed DEBUG from the patch (as was done in our production branches,
  but missing from the patch-prep branch)
- updated SJG's comment (with a TODO for the RK3288) to reflect the
  new code structure
