[PATCH 51/55] media: rkisp1: Add and set registers for output size config on i.MX8MP

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

 



The ISP version in the i.MX8MP has a set of registers currently not
handled by the driver for output size configuration. Add a feature flag
to determine if the ISP requires this, and set the registers based on
that.
