[PATCH v7 0/8] drm/mediatek: Add mt8195 DisplayPort driver

[Guillaume Ranquet <granquet@baylibre.com>]

this series is built around the DisplayPort driver. The dpi/dpintf
driver and the added helper functions are required for the DisplayPort
driver to work.

In v7 I've adressed the comments from the community:
- clean the checkpatch --strict output
- better split up of the patches (some bad fixup were done in v6...)
- use of devm_phy_get()
- make the "ck_cg" clock optional as to not break the other platforms.

There's still some leftover comments from Chun Kuang as can be seen in this thread:
https://lore.kernel.org/linux-mediatek/CABnWg9v-QBAaJ0MffNNSKCNyd8eb1zhETxoZjxQ5c7FNeUkBAg@mail.gmail.com/

- mtk_dp_poweron() stayed in mtk_dp_bridge_attach() as the change breaks eDP
- That request was left un-addressed as I'm not sure what to do with it.
	> > Refer to mtk_hdmi_bridge_atomic_enable() for getting the mode.
