Hello!
Here's the set of 2 patches against Simon Horman's 'renesas.git' repo's
'renesas-devel-20180529-v4.17-rc7' tag. We're adding the R8A77980 I2C nodes
and then describing 2 PCA9654 I/O expanders connected to the I2C0 bus on
the Condor board.

Define the Condor board dependent part of the I2C0 device node.
The I2C0 bus is populated by 2 ON Semiconductor PCA9654 I/O expanders
and Analog Devices ADV7511W HDMI transmitter (but we're only describing
the former chips now).
