[-- Attachment #1: arm64-dts-renesas-eagle-add-I2C0-support.patch --]
[-- Type: text/plain, Size: 1328 bytes --]
Define the Eagle board dependent part of the I2C0 device node.
The I2C0 bus is populated by ON Semiconductor PCA9653 I/O expander and
Analog Devices ADV7511W HDMI transmitter (but we're only describing the
former chip now).
Based on the original (and large) patch by Vladimir Barinov.
