[PATCH v2 1/2] drm/mipi-dsi: add flag for sending all DSC slices in one packet

[Alexander Koskovich]

The MIPI DSI v1.3 spec defines two modes for transporting compressed
pixel data: one slice per packet or multiple slice widths in a single
packet (Section 8.8.24 Figure 40).

Add a MIPI_DSI_MODE_DSC_ALL_SLICES_IN_PKT flag that panel drivers can
set to indicate that all DSC slices for a line should be packed into a
single packet. When unset should default to 1 slice per packet.
