This series of patches includes support, tests and fixes for
adding PCA9552 and PCA9554 I2C devices to the powernv10 chip.
The PCA9552 device is used for PCIe slot hotplug power control
and monitoring, while the PCA9554 device is used for presence
detection of IBM CableCard devices. Both devices are required
by the Power Hypervisor Firmware on Power10 platforms.
Changes from previous version:
- Pulled in fixes/changes for pca9552 devices
- Created new powernv10-rainier machine type
- Adds pca9552/pca9554 devices to powernv10-rainier machine
- Modified MAINTAINERS to make myself maintainer of
the pca955x devices
