Resend because the earlier recipient list was wrong.

Now that drm/tidss is queued for mainline, lets add display support for k2g-evm. There is no hurry since tidss is out only in v5.7, but it should not harm to have the dts changes in place before that.

New subject: [PATCH resend 1/2] ARM: dts: keystone-k2g: Add DSS node

Add DT node for DSS. K2G has DSS version 6. Keystone family DSS are somewhat different compered to the old OMAP family DSSes and the binding looks different too.

New subject: [PATCH resend 2/2] ARM: dts: keystone-k2g-evm: add HDMI video support

Add DT nodes for HDMI video support for K2G EVM. The HDMI uses SiI9022 DPI as HDMI encoder. The DSS DPI is connected to SiI9022 HDMI encoder's video input and encoder's output goes to HDMI connector.

What happened with this one? It used to be in linux-next, but now I don't see it anymore.

Pull request [1] was sent during last merge window. Thought it was picked up but doesn't seems to be. Have sent question to arm-soc maintainers.
