All of the devices in the Sony Yoshino platform are using a Synaptics
RMI4-compatible touch IC with identical pins and supplies: enable the
I2C-5 bus and add the rmi4-i2c node along with the required pin

"touchscreen" sounds like a better "generic name" for the node.

Haven't checked the following patches yet, do you need the label?


Thank you, I forgot to remove the label after a cleanup.
Also, node name changed.
