From eacc813b31a0aa2a530ca034abf7029f954c8195 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Date: Mon, 15 Feb 2021 05:27:17 +0100 Subject: [PATCH] media: imx: imx7-media-csi: Remove double reflash of DMA controller The DMA controller needs to be reflashed after being configured. There is however no need to do it twice, once in imx7_csi_configure() and once in imx7_csi_sw_reset(), called from imx7_csi_enable(). Remove the former.
