The controller is similar to the one found on the H3, with the addition of a MIPI CSI-2 interface. However, this series only supports parallel and BT.656 interfaces, based on the existing driver. Patch 1 adds an undocumented clock parent of the CSI MCLK. This was found after finding the default value to sometimes work and sometimes not, and then comparing against BSP code. Patch 2 adds a compatible string for the A83T variant. Patch 3 adds support for the A83T variant to the existing sun6i-csi driver. Patch 4 adds a device node for the controller, as well as commonly used pin muxing options. Patch 5 adds a pin muxing option for I2C1 on the PE pins, used in conjunction with the CSI pins. Patch 6 provides an example usage of the CSI controller: the Bananapi M3 with its camera module attached. Please have a look.
