From bfaf91ca848e758ed7be99b61fd936d03819fa56 Mon Sep 17 00:00:00 2001 From: Joakim Zhang Date: Thu, 25 Feb 2021 17:01:12 +0800 Subject: net: stmmac: fix dma physical address of descriptor when display ring Driver uses dma_alloc_coherent to allocate dma memory for descriptors, dma_alloc_coherent will return both the virtual address and physical address. AFAIK, virt_to_phys could not convert virtual address to physical address, for which memory is allocated by dma_alloc_coherent. dwmac4_display_ring() function is broken for various descriptor, it only support normal descriptor(struct dma_desc) now, this patch also extends to support all descriptor types.
