Hi, Markus: Markus Schneider-Pargmann [off-list ref] 於 2021年9月7日 週二 上午3:37寫道：
This patch adds a DisplayPort driver for the Mediatek mt8195 SoC.
It supports both functional units on the mt8195, the embedded
DisplayPort as well as the external DisplayPort units. It offers
hot-plug-detection, audio up to 8 channels, and DisplayPort 1.4 with up
to 4 lanes.
This driver is based on an initial version by
Jason-JH.Lin [off-list ref].

Notes:
Changes RFC -> v1:
- Removed unused register definitions.
- Replaced workqueue with threaded irq.
- Removed connector code.
- Move to atomic_* drm functions.
- General cleanups of the code.
- Remove unused select GENERIC_PHY.

It seems that register 0x1000 ~ 0x1fff is to control phy and 0x2000 ~ 0x4fff is to control non-phy part. For mipi and hdmi, the phy part is an independent device [1] and the phy driver is independent [2] , so I would like this phy to be an independent device.
