[PATCH v4 0/3] media: imx: add support for imx8mq MIPI RX

From: Martin Kepplinger
Date: Mon Jun 14 2021 - 08:16:17 EST


hi,

This patch series adds a driver for the i.MX8MQ CSI MIPI receiver / controller.

It includes the driver, the dt-bindings and the DT addition to the SoC dtsi.

This is the vendor driver I'm basing the hardware-side of the driver on:
https://source.codeaurora.org/external/imx/linux-imx/tree/drivers/media/platform/imx8/mxc-mipi-csi2_yav.c?h=imx_5.4.70_2.3.0

Thanks Laurent who helped a lot. I'm happy for any feedback,

martin
