Subject: [PATCH v2 0/3] drm/rockchip: Add driver for the new DSI2 controller

This series adds a bridge and glue driver for the DSI2 controller found
in the rk3588 soc from Rockchip, that is based on a Synopsis IP block.

As the manual states:
The Display Serial Interface 2 (DSI-2) is part of a group of communication
protocols defined by the MIPI Alliance. The MIPI DSI-2 Host Controller is
a digital core that implements all protocol functions defined in the
MIPI DSI-2 Specification.


While the driver structure is very similar to the previous DSI controller,
the programming model of the core is quite different, with a completely
new register set.

Another notable difference is that the phy interface is variable now too
in its width and some other settings.

changes in v2:
- clean up includes (Diederik)
- fix Kconfig description (Diederik)
- constant naming (Diederik)
- binding fixes (paths, sorting, labels) (Rob)
- move to use regmap
- drop custom UPDATE macro and use FIELD_PREP instead
- use dev_err instead of DRM_DEV_ERROR
