Subject: [PATCH] MIPS: SGI-IP22: provide missing dma_mask/coherent_dma_mask
Date: Mon, 13 May 2019 13:16:08 +0200 [thread overview]
Message-ID: <20190513111609.14855-1-tbogendoerfer@suse.de> (raw)
Set dma_masks for SGIWD93 and SGISEEQ otherwise DMA allocations fails
and causes not working SCSI/ethernet.
