Subject: [PATCH v2] staging: media: imx: Kconfig: support VIDEO_IMX7_CSI for imx8m
Date:   Wed,  2 Dec 2020 14:12:51 +0100
Message-Id: <20201202131251.3422-1-martin.kepplinger@puri.sm>
Content-Transfer-Encoding: 8bit
Precedence: bulk

As described in NXPs' linux tree, the imx8m SoC includes the same
CSI bridge hardware that is part of imx7d. We should be able to
use the "fsl,imx7-csi" driver for imx8m directly.

Since ipuv3 is not relevant for imx8m, move that dependency to
VIDEO_IMX_CSI. That makes VIDEO_IMX7_CSI available to support imx8m
too.

v2: (thanks Philipp and Hans for feedback)
  * make only VIDEO_IMX_CSI build imx6-media and thus make VIDEO_IMX_MEDIA
    only build common which can be use by all modules.
