Subject: [PATCH] drm/vc4: crtc: Rename HVS channel to output
|
|
|
|
In vc5, the HVS has 6 outputs and 3 FIFOs (or channels), with
|
|
pixelvalves each being assigned to a given output, but each output can
|
|
then be muxed to feed from multiple FIFOs.
|
|
|
|
Since vc4 had that entirely static, both were probably equivalent, but
|
|
since that changes, let's rename hvs_channel to hvs_output in the
|
|
vc4_crtc_data, since a pixelvalve is really connected to an output, and
|
|
not to a FIFO.
