From eb0c062161cf5f98556a906c48b0cfc019d9e89c Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 16 Sep 2024 15:33:20 +0200 Subject: gpu: host1x: Set up device DMA parameters In order to store device DMA parameters, the DMA framework depends on the device's dma_parms field to point at a valid memory location. Add backing storage for this in struct host1x_memory_context and point to it.
