-Subject: [PATCH 660/806] staging: vchiq: Use the old dma controller for OF
- config on platform devices
-
-vchiq on Pi4 is no longer under the soc node, therefore it
-doesn't get the dma-ranges for the VPU.
-
-Switch to using the configuration of the old dma controller as
-that will set the dma-ranges correctly.
