Display support for rk3228/rk3229 (up to hdmi output) and more love
for rk3288-veyron boards.

* tag 'v5.3-rockchip-dts32-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  ARM: dts: rockchip: add display nodes for rk322x
  ARM: dts: rockchip: fix vop iommu-cells on rk322x
  clk: rockchip: add clock id for hdmi_phy special clock on rk3228
  clk: rockchip: add clock id for watchdog pclk on rk3328
  Revert "ARM: dts: rockchip: set PWM delay backlight settings for Minnie"
  ARM: dts: rockchip: Configure BT_DEV_WAKE in on rk3288-veyron
  ARM: dts: rockchip: Configure BT_HOST_WAKE as wake-up signal on veyron
