Subject: [PATCH v7 0/5] Add support for HiSilicon I2C controller

Add driver and MAINTAINERS for HiSilicon I2C controller on Kunpeng SoC. Also
provide the devm_*() variants for adding the I2C adapters. Add a public
api to provide I2C frequency mode strings and convert designware driver
to use it.

Change since v6:
- make the i2c_freq_mode_string() exported rather than inline
- addressed the comments from Wolfram and Jarkko for the driver

Change since v5:
- address the comment from Dmitry and add his Reviewed-by
- address the comment from Jarkko and add his Reviewed-by and Tested-by
- add Jarkko's Acked-by for designware patch

Change since v4:
- and Andy's Reviewed-by
- attach Andy's patch of switch designware driver to use i2c_freq_mode_string()

Link: https://lore.kernel.org/linux-i2c/20210330134633.29889-1-andriy.shevchenko@linux.intel.com/

Change since v3:
- split the bus mode string api to I2C as suggested by Andy
- simplify the devm variants and change the export format
- address the comments of the HiSilicon I2C driver from Andy and Dmitry, thanks!

Link: https://lore.kernel.org/linux-i2c/1615296137-14558-1-git-send-email-yangyicong@hisilicon.com/

Change since v1:
- fix compile test error on 32bit arch, reported by intel lkp robot:
  64 bit division without using kernel wrapper in probe function.
