[PATCH 0/5] Fix RG35XX Battery Charging Issues

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

The Anbernic RG35XX devices sometimes fail to charge when the register
for the battery temperature sensor is set to the incorrect value either
by user error or an incorrectly programmed efuse. Allow users to
hard-code if a temperature sensor is not present (which is the case for
all Anbernic RGxx series devices) to prevent this issue from causing
problems. Additionally, a bug was identified with the handling of PMU
faults while this fix was being tested.

[PATCH 1/5] power: supply: axp20x_battery: Fix fault handling for AXP717

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Correct the fault handling for the AXP717 by changing the i2c write
from regmap_update_bits() to regmap_write_bits(). The update bits
function does not work properly on a RW1C register where we must
write a 1 back to an existing register to clear it.

Additionally, as part of this testing I confirmed the behavior of
errors reappearing, so remove comment about assumptions.

[PATCH 2/5] dt-bindings: power: supply: axp20x-battery: Add x-powers,no-thermistor

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Add the vendor specific boolean property of x-powers,no-thermistor.
This property optionally describes hardware where no thermistor is
present on the battery and is specific to the AXP717. In rare
circumstances this value can be set incorrectly in the efuse of the
PMIC, and if it is not hard-coded the device will fail to charge.

Please add a separate entry. As you can see immediately below,
there is a separate entry for the IRQ status registers. We're
not allowing writes to unknown registers.

[PATCH 4/5] power: supply: axp20x_battery: Update temp sensor for AXP717 from device tree

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Allow a boolean property of "x-powers,no-thermistor" to specify devices
where the ts pin is not connected to anything. This works around an
issue found with some devices where the efuse is not programmed
correctly from the factory or when the register gets set erroneously.

AFAICT this function won't get run if there is no "monitored-battery"
property under the PMIC node. So if someone were to unfortunately have
a dev board that has a PMIC with incorrect efuse values, this won't
save them.

This should be exceedingly rare, so I only ask that you mention this
in the comment so if someone does unfortunately run into it they will
have some clue.

Lee, FYI this power supply patch has a compile time dependency on the
mfd patch, due to the new register offset macro.

Chris, in the future, if you are aware of build time dependencies,
please mention them in the cover letter. That would help maintainers
sort out how to land things.


Thanks
