[PATCH 00/17] video: dw_hdmi: Support Vendor PHY

[Jagan Teki]

Unlike RK3399, Sunxi/Meson DW HDMI the new Rockchip SoC Rk3328 would
support external vendor PHY with DW HDMI chip.

Support this vendor PHY by adding new platform PHY ops via DW HDMI
driver and call the respective generic phy from platform driver code.

This series tested in RK3328 with 1080p (1920x1080) resolution.

Patch 0001/0005: Support Vendor PHY
Patch 0006/0008: VOP extension for win, dsp offsets
Patch 0009/0010: RK3328 VOP, HDMI clocks
Patch 0011:	 Rockchip Inno HDMI PHY
Patch 0012:	 RK3328 HDMI driver
Patch 0013:	 RK3328 VOP driver
Patch 0014/0017: Enable HDMI Out for RK3328

Importent:
One pontential issues is that Linux HDMI out on RK3328 has effected by
this patchset as I wouldn't find any relation or clue.

The only way I can use Linux HDMI by disabling IOMMU or support
disable-iommu link for RK3328 via DT [1].
