[PATCH v5 0/3] media: i2c: isl7998x: Add driver for Intersil ISL7998x

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is v5 of the series to for adding the isl7998x driver [0]

The isl7998x is an analog video to MIPI CSI-2 or BT.656 converter. The dt
binding describes only the isl79987 chip, which supports MIPI CSI-2. The
driver could be extended to handle isl79988 (for BT.656), too, but this isn't
implemented.

In v5, I fixed the pre_streamon subdev call from imx6-mipi-csi2 to ensure
backward compatibility with subdev drivers that do not implement pre_streamon
as suggested by Philipp Zabel.
