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.
I went quickly through all patches in the series except the one that
adds
the bindings, and I've spotted no glaring issues. My main focus was on
ensuring there should be no regressions.
Thus, not worth a Reviewed-by tag, but still counting as a review.
