The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0331/1085] 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.

+ This module supports the PWM fan controller found on the Raspberry Pi
