[PATCH 0/5] Add RK816 PMIC support

[Alex Bee <knaerzche@xxxxxxxxx>]

This series aims to add support for Rockchip RK816 PMIC series. As per
datasheet it's targeted for RK3126/RK3128 (RK816-1), RK1108 (RK816-2) and
PX3-SE (RK816-3) but might be used for other SoCs as well. The mfd consists
of an integrated RTC, a GPIO controller, two 32k clock outputs, a power key
(output), 4 buck- and 5 ldo regulators, 3 regulator-switches, and charger
with integrated fuel gauge. Charger and fuel gauge are not part of this
series. Two of the switches (otg/boost) are part of the binding, but not of
the driver. They must only ever by enabled if no battery charging is
happening, but it will be enabled automatically if a battery is attached.
Thus they need some incorporation of a yet to be added charger driver.
Integration in the existing rk8xx-infrastructure was pretty straightforward
and only needed very little tweaking. In order to not further bloat the
driver(s) too much with additional definitions I tried to re-use existing
ones wherever possible.

The patches are loosely based on the vendor's implementation, verified
against the datasheet and tested/measured on RK3126 board. As they are
touching several subsystems I'm sending them (very) early for the
6.10-cycle.
