[PATCH 0/2] drm/bridge: ti-tfp410: Handle bus-format for 24/12 lines selection

[Peter Ujfalusi]

Hi,

The TFP410 supports 24 bit, single-edge and 12 bit, dual-edge modes.
Depending on how many wires are used (24/12) the driver can set the correct
bus_format.

In case the bus-width is not specified (old DT blobs) assume 24 lines as the
driver assumed that in the past and all boards using tfp410 uave this setup.

Regards,
Peter

[PATCH 1/2] dt-bindings: display: tfp410: Add bus-width parameter property

[Peter Ujfalusi]

tfp410 can be connect to host processor in 24bit, single-edge (24 lines) or
12bit, dual-edge (12 lines).

Add bus-width to the documentation so it can be used to select between the
two connection scheme.

[PATCH 2/2] drm/bridge: ti-tfp410: Set the bus_format

[Peter Ujfalusi]

The TFP410 supports 24 bit, single-edge and 12 bit, dual-edge modes.
Depending on how many wires are used (24/12) the driver can set the correct
bus_format.

If the information is not available in DT then assume 24 bit, single-edge
setup.
