[PATCH 1/5] dt-bindings: display: rockchip: Add rk3576 DisplayPort

From: Andy Yan

Date: Fri Jan 09 2026 - 03:03:19 EST


From: Andy Yan <andy.yan@xxxxxxxxxxxxxx>

The DisplayPort found on RK3576 is very similar to that of RK3588,
but work in dual pixel mode. And itself does not depend on the I2S
clock or the SPDIF clock when transmit audio.
