Subject: [PATCH v2 0/5] Add RK816 PMIC support
Date: Sat, 23 Mar 2024 09:58:47 +0100 [thread overview]
Message-ID: <20240323085852.116756-1-knaerzche@gmail.com> (raw)
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, 3 buck- and 6 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 be enabled if no battery charging is
happening, but it will be enabled automatically if a battery is attached
and an external power source is connected. Thus that needs 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 `#define`s 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 a RK3126 board. As they are
touching several subsystems I'm sending them (very) early for the
6.10.-cycle.
changes since v1:
- integrated Krzysztof's feedback for the bindings and the resulting
driver changes
- fixed a sparse warning
