Subject: [PATCH v3 00/16] add support for AXP813 ADC and battery power supply
Date: Mon, 15 Jan 2018 11:33:34 +0100 [thread overview]
Message-ID: <cover.2e5329bf5475a5160e613a4eb1e1377c662ce56e.1516012352.git-series.quentin.schulz@free-electrons.com> (raw)
The AXP813 PMIC is relatively close to the already supported AXP20X and
AXP22X. It provides three different power outputs: battery, AC and USB, and
measures a few different things: temperature, power supply status, current
current and voltage supplied, maximum current limit, battery capacity, min
and max voltage limits.
One of its two GPIOs can be used as an ADC.
There are a few differences with AXP20X/AXP22X PMICs though:
- a different constant charge current formula,
- battery temperature, GPIO0 and battery voltages are the only voltages
measurable,
- all data are stored on 12 bits (AXP20X/AXP22X had one type of data that
was stored on 13 bits),
- different scales and offsets,
- a different ADC rate formula and register,
This patch series adds support for the PMIC's ADC and battery power supply
in the existing drivers.
Make the axp20x MFD automatically probe the ADC driver, add the battery
power supply node in axp81x node and enable it for the TBS A711 since it
has a soldered battery.
I suggest patches:
- 4,5,8,14,15,16 go through Maxime and Chen-Yu's tree,
- 1,2,3,7 go through Jonathan's tree,
- 6,9,13 go through Lee's tree,
- 10,11,12 go through Sebastian's tree,
v3:
- merging dt-bindings patches for axp_adc as requested by Rob,
- re-ordered constant in IIO driver as requested by Julian,
- compatibles for ADC are now named after the first design that
introduced the IP instead of wildcard as requested by Maxime,
- renamed DT node name from axp-adc to adc as requested by Rob,
- replaced enumeration of supported PMICs in battery power supply DT
bindings documentation by "supported devices" as requested by Jonathan,
- added a new patch for removing "axp-" from axp81x's pinctrl DT node,
v2:
- introduce data structure instead of ID for variant specific code in
battery driver,
- add DT binding for ADC driver,
- make mfd probe the ADC driver via DT as well so that its IIO channels
can be consumed by other drivers via DT mapping,
Thanks,
Quentin
