Subject: [PATCH v2 0/2] i2c: uniphier: add two I2C controller drivers for UniPhier SoC platform


This series adds two I2C controller drivers.
(they are completely different IPs.)

The first one is a very simple FIFO-less I2C controller,
which is used on some older UniPhier SoCs.

The other one is higher-performance I2C controller with TX/RX FIFO,
used on newer UniPhier SoCs.


Changes in v2:
  - Delete if-block after platform_get_resource()
  - Add I2C_FUNC_SMBUS_EMUL to functionality
  - Add bindings document
  - Add entry to MAINTAINERS
  - Delete if-block after platform_get_resource()
  - Add I2C_FUNC_SMBUS_EMUL to functionality
  - Add bindings document
  - Fix a typo in a comment block

  i2c: uniphier: add UniPhier FIFO-less I2C driver
  i2c: uniphier_f: add UniPhier FIFO-builtin I2C driver
