From 78bc671bd1501e2f6c571e063301a4fdc5db53b2 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 18 Oct 2024 12:47:39 -0700 Subject: scsi: ufs: core: Make DMA mask configuration more flexible Replace UFSHCD_QUIRK_BROKEN_64BIT_ADDRESS with ufs_hba_variant_ops::set_dma_mask. Update the Renesas driver accordingly. This patch enables supporting other configurations than 32-bit or 64-bit DMA addresses, e.g. 36-bit DMA addresses.
