Subject: [PATCH v3 08/15] clk: sunxi-ng: a523: add video mod clocks
Add the clocks driving the various video subsystems of the SoC: the "DE"
display engine, the "DI" deinterlacer, the "G2D" 2D graphics system, the
Mali "GPU", the "VE" video engine, its associated IOMMU, as well as the
clocks for the various video output drivers (HDMI, DP, LCDs).
