Subject: [PATCH 0/6] mfd: 88pm800: Add 88pm860 device support

88PM860 falls under 88pm800 family of devices, with some feature
additions, for example, support for dual phase on BUCK1.

This patch series, enabled chip ID support for 88pm860 in the driver
and adds,
  - Init time configuration support based on chip ID
  - DT property for 32KHz low jitter clock enable
  - DT property for dual phase enable

TODO:
 - Some of init time configurations are common to both 88pm800 and 88pm860
   devices, but since I can not validate it, decided to move it to
   88pm860 block only.
   But if someone is willing to help me in validation, we can move it to
   common code later. No issues there.
 - Sleep/low-power-mode related configuration is also part of init time,
   but since we are too far from sleep mode support and without testing
   I do not want add anything, decided to take it later when we actually
   start looking at sleep support.
 - Init time configuration also includes pinmux setting for the device.
   I am working on using pinctrl-single driver to have standard and generic
   interface, hopefully it will get handled through pinctrl subsystem.
