[PATCH v2 1/5] dt-bindings: display: rockchip: Add rk3576 DisplayPort

[Andy Yan]

From: Andy Yan <andy.yan at rock-chips.com>

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.
