From b5d69129ea2b86d8a357efe3eca664b44860406e Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Thu, 12 Jul 2018 15:42:55 +0200 Subject: mips/jazz: provide missing dma_mask/coherent_dma_mask Commit 205e1b7f51e4 ("dma-mapping: warn when there is no coherent_dma_mask") introduced a warning, if a device is missing a coherent_dma_mask. ESP and sonic are using dma mapping functions, so they need dma masks.
