+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.
