This series adds support for the official keyboard case for the Pine64
PinePhone and PinePhone Pro. This accessory contains a keyboard MCU and
an IP5209 power bank IC. The keyboard MCU firmware[0] is free software.
It exposes the keyboard scan matrix over I2C, and also provides commands
for SMBus access to the IP5209. In order to keep the IP5209 driver[1]
generic, this is modeled as an I2C bus child of the keyboard.
