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.
