Subject: [PATCH 6/7 v5] bus: fsl-mc: set coherent dma mask for devices on fsl-mc bus
Date: Sun, 20 May 2018 19:19:50 +0530 [thread overview]
Message-ID: <1526824191-7000-7-git-send-email-nipun.gupta@nxp.com> (raw)
In-Reply-To: <1526824191-7000-1-git-send-email-nipun.gupta@nxp.com>
of_dma_configure() API expects coherent_dma_mask to be correctly
set in the devices. This patch does the needful.
