Subject: [PATCH 6/7 v7] bus/fsl-mc: set coherent dma mask for devices on fsl-mc bus
Date: Mon, 10 Sep 2018 19:19:20 +0530 [thread overview]

In-Reply-To: <1536587361-11047-1-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.
