Subject: [PATCH v1 0/6] ARM: Add GXP I2C Support

From: Nick Hawkins <nick.hawkins@....com>

The GXP SoC supports 10 I2C engines. Each I2C engine is completely
independent and can function both as an I2C master and I2C slave. The
I2C master can operate in a multi master environment. The engines support
a scalable speed from 8kHZ to 1.5 Mhz.

Nick Hawkins (6):
  i2c: hpe: Add GXP SoC I2C Controller
  dt-bindings: i2c: hpe,gxp-i2c
  dt-bindings: mfd: syscon: Document GXP register compatible
  ARM: dts: hpe: Add I2C Topology
  ARM: multi_v7_defconfig: add gxp i2c module
  MAINTAINERS: Add HPE GXP I2C Support
