Subject: [PATCH 0/5] Add DisplayPort support for rk3576

From: Andy Yan <andy.yan@...k-chips.com>


The DisplayPort found on RK3576 is very similar to that of RK3588,
but work in qual pixel mode and support for MST.

This patch series aims to add basic display output, not include audio
and MST, which will be the work for the next stage.

Only test with 2 lane standard DP port output now.
