When the new register addresses were introduced for V3D 7.x, we added
new masks for performance counter sources on V3D 7.x. Nevertheless,
we never apply these new masks when setting the sources.

a new macro, `V3D_SET_FIELD_VER`

Calling drm_connector_cleanup() should only be done via the free_cb =>
.destroy path, which cleans up the struct drm_connector only when the
refcount drops to zero.
A cleanup done with a refcount higher than 0 can result from buggy code,
e.g. by doing cleanup directly in the drivers teardown code.
This series brings small improvements to the DRM documentation, logging and
a warning on an incorrect code path.

This adds the glue code for the MIPI DSI2 bridge on Rockchip SoCs and
enables its use on the RK3588.
Right now the DSI2 controller is always paired with a DC-phy based on a
Samsung IP, so the interface values are set statically for now.
This stays true for the upcoming RK357

The Display Serial Interface 2 (DSI-2) is part of a group of communication
protocols defined by the MIPI Alliance. The RK3588 implements this
specification in its two MIPI DSI-2 Host Controllers that are based on a
new Synopsis IP.

Add a wrapper to kref_read() just like the ones already in place for
kref_get() and kref_put(). This will be used for sanity checks on object
