[PATCH v2 1/7] ARM: dts: sun4i: Add CSI1 controller and pinmux options

Chen-Yu Tsai wens at kernel.org
Mon Jan 6 00:42:34 PST 2020


From: Chen-Yu Tsai <wens at csie.org>

The CSI controller driver now supports the second CSI controller, CSI1.

Add a device node for it. Pinmuxing options for the MCLK output, the
standard 8-bit interface, and a secondary 24-bit interface are included.
