Subject: [PATCH] mfd: simple-mfd-i2c: Add configuration for RPi POE HAT
|
|
|
|
The Raspbery Pi PoE+ HAT exposes a fan controller and power
|
|
supply status reporting via a single I2C address.
|
|
|
|
Create an MFD device that allows loading of the relevant
|
|
sub-drivers, with a shared I2C regmap.
