arm64: dts: meson: kvim3: move hdmi to tdm a (f3150508) · Commits · 戴 / test

The tdmout b is physically routed to the 40 pin header and the tdmout c is routed to the m2 connector. It makes these interfaces poor candidates to handle the HDMI 8ch i2s link (2ch i2s * 4 lanes) as it would force the same link format on the related connectors. Instead use the TDM A interface. This one is not routed to the outside world on the vim3, so it can only be used for HDMI. Signed-off-by:
