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 (CONFIG_IP5XXX_POWER) generic, this is modeled as a child I2C bus.
