Subject: [PATCH 11/14] ARM: dts: sun8i: r40: Add device node for CSI0
Date:   Mon, 16 Dec 2019 00:59:21 +0800

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

The CSI0 and CSI1 blocks are the same as found on the A20. However only
CSI0 is supported upstream right now.

Add a device node for CSI0 using the A20 compatible as a fallback, and
the standard pinctrl options. Also add the MBUS interconnect.
