From 971a2bb14b459819db1bda8fcdf953e493242b42 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Tue, 19 May 2020 16:20:30 +0100 Subject: [PATCH] drm/vc4: Add FKMS as an acceptable node for dma ranges. Under FKMS, the firmware (via FKMS) also requires the VideoCore cache aliases for image planes, as defined by the dma-ranges under /soc. Add rpi-firmware-kms to the list of acceptable nodes to look for to copy dma config from.
