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 the Power10 Ranier platform.
Changes from previous version:
- Removed two already merged patches
- Various formatting changes
- Capitalized "Rainier" in machine description string
- Changed powernv10-rainier parent to MACHINE_TYPE_NAME("powernv10")
Nick,
could this series go through the ppc-next queue ?
Thanks,
C.
