Subject: [PATCH 0/6] ARM: sun8i: a83t: Support Camera Sensor Interface controller

From: Chen-Yu Tsai <wens@...e.org>

Hi everyone,

This series adds support for the camera sensor interface controller
found on the Allwinner A83T SoC. 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.

Regards
ChenYu
