Subject: [RFC v2 0/4] power: supply: Add Support for RK817 Charger
Date: Mon, 26 Jul 2021 14:01:26 -0500 [thread overview]
Message-ID: <20210726190130.1973-1-macroalpha82@gmail.com> (raw)
From: Chris Morgan <macromorgan@hotmail.com>
As this is my first charger driver, I'm submitting it as an RFC so I
can get input from the community on what else is needed to make the
driver consistent with the quality upstream expects.
This series is to add support for the Rockchip rk817 battery charger
which is present in all Rockchip RK817 PMICs. The driver was written
as a joint effort by Maya Matuszczyk <maccraft123mc@gmail.com> and
myself Chris Morgan <macromorgan@hotmail.com>.
The driver requires some basic parameters be described about the
battery in the devicetree such as the maximum capacity, the minimum
and maximum voltage for the battery, the maximum charge current, the
maximum charge voltage, and the value of sample resistors and sleep
currents.
The hardware itself contains an ADC capable of measuring the voltage,
current, and temperature of the battery (though my implementation of an
Odroid Go Advance lacks a thermistor for temperature). It also contains
a columb counter, registers for tracking the measured voltage and
current at boot, and a few bytes of nvram for storing data.
Changes from V1:
- Fixed a CLANG warning regarding an uninitalized variable.
- Fixed a CLANG warning regarding a pointer as a bool value always
returning as true.
- Added Maya Matuszczyk to the Signed-off-by.
