Hello, This small patch series converts the three subdevs of the rkisp1 (CSI, ISP and resizer) to use the V4L2 subdev active state. This simplifies the implementation of the subdevs, as well as the locking scheme. There isn't much else to add here, please see individual patches for details. I have successfully tested this series on an i.MX8MP (Debix) and an RK3399 (Rock Pi 4).
