From bc65b13eddc35f0cf5b429ca143b9394a6826707 Mon Sep 17 00:00:00 2001 From: Umang Jain Date: Sat, 23 Sep 2023 20:01:55 +0530 Subject: staging: vc04_services: bcm2835-camera: Explicitly set DMA mask In the following patches, vchiq_arm will be migrated to create and use its own bus and all the vchiq drivers (bcm2835-camera, bcm2835-audio) will be registered to it. Since the platform driver/device model internally sets the DMA mask for its registered devices, we would have to do it ourself when we remove the platform driver/device registration for vchiq devices. This patch explicitly sets the DMA mask to bcm2835-camera so as not to introduce a regression when we move away from platform device/driver model.
