[PATCH] media: imx: Unstage the imx8mq-mipi-csi2 driver

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

 



The imx8mq-mipi-csi2 mipi receiver driver is used and maintained. There
is no reason to keep it in staging. The accompanying CSI bridge driver that
uses it is in drivers/media/platform/nxp as well.

One TODO is to get rid of csi_state's "state" and "lock" variables. Especially
make sure suspend/resume is working without them. That can very well be worked
on from the new location.

Add a MAINTAINERS section for the imx8mq-mipi-csi2 mipi receiver driver.
It shares the CSI Bridge driver with the one from imx7 and imx8mm so the
sections overlap a bit.
