Subject: [PATCH v2 0/8] Add powernv10 I2C devices and tests
Date: Fri, 10 Nov 2023 13:49:17 -0600	[thread overview]
Message-ID: <20231110194925.475909-1-milesg@linux.vnet.ibm.com> (raw)

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.

Glenn Miles (8):
  ppc/pnv: Add pca9552 to powernv10 for PCIe hotplug power control
  ppc/pnv: Wire up pca9552 GPIO pins for PCIe hotplug power control
  ppc/pnv: PNV I2C engines assigned incorrect XSCOM addresses
  ppc/pnv: Fix PNV I2C invalid status after reset
  ppc/pnv: Use resettable interface to reset child I2C buses
  misc: Add a pca9554 GPIO device model
  ppc/pnv: Add a pca9554 I2C device to powernv10
  ppc/pnv: Test pnv i2c master and connected devices
