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: - Added prerequisite patch that hasn't merged into master yet. (see patch 1/8 for details). Without this patch, the code compiles but "make check" fails.
