drm: rcar-du: Recognize "renesas,vsps" in addition to "vsps"

2019-12-18T00:40:10+00:00

The Renesas-specific "vsps" property lacks a vendor prefix.
Add a "renesas," prefix to comply with DT best practises.
Retain backward compatibility with old DTBs by falling back to "vsps"
when needed.

drm: rcar-du: kms: Initialize CMM instances

2019-12-18T00:40:04+00:00

Implement device tree parsing to collect the available CMM instances
described by the 'renesas,cmms' property. Associate CMMs with CRTCs and
store a mask of active CMMs in the DU group for later enablement.

Enforce the probe and suspend/resume ordering of DU and CMM by creating
a stateless device link between the two.

drm: rcar-du: kms: Expand comment in vsps parsing routine

2019-10-15T21:27:54+00:00

Expand comment in the 'vsps' parsing routine to specify the LIF
channel index defaults to 0 in case the second cell of the property
is not specified to remain compatible with older DT bindings.

drm: rcar-du: Skip LVDS1 output on Gen3 when using dual-link LVDS mode

2019-06-07T23:36:04+00:00

In dual-link LVDS mode, the LVDS1 encoder is used as a companion for
LVDS0, and both encoders transmit data from DU0. The LVDS1 output of DU1
can't be used in that case, don't create an encoder and connector for
it.

drm: rcar-du: Add writeback support for R-Car Gen3

2019-03-18T15:24:51+00:00

Implement writeback support for R-Car Gen3 by exposing writeback
connectors. Behind the scene the calls are forwarded to the VSP
backend.

Using writeback connectors will allow implemented writeback support for
R-Car Gen2 with a consistent API if desired.
