[PATCH v1 0/9] ARM: Add GPIO and PSU Support

[nick.hawkins at hpe.com]

From: Nick Hawkins <nick.hawkins at hpe.com>

The GXP has multiple interfaces that provide I/O to it. There is GPIO
coming from the host and from the cpld. Both of these interfaces are
interruptable.

The GXP is able to monitor PSU's via I2C. There is support for up to 8
PSUs. The GXP gets presence information from I/O with the cpld.

The fan controller and the psu monitor consume I/O from the CPLD.
Thus for the GXP to be able to report this GPIO to the OpenBMC stack
calls have been enabled for the GPIO driver to use.

Nick Hawkins (9):
  gpio: gxp: Add HPE GXP GPIO
  hwmon: (gxp_fan_ctrl) Give GPIO access to fan data
  hwmon: (gxp-psu) Add driver to read HPE PSUs
  dt-bindings: hwmon: Modify hpe,gxp-fan-ctrl
  dt-bindings: gpio: Add HPE GXP GPIO
  dt-bindings: hwmon: Add HPE GXP PSU Support
  ARM: dts: gxp: add psu, i2c, gpio
  ARM: multi_v7_defconfig: Add PSU, GPIO, and I2C
