From 8ebb2cf0f6f42be258795a87fbe31d77440be20d Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 3 Sep 2020 10:00:42 +0200 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.
