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. Note that the MFD updates to the writeable regs are required build dependencies of the battery fix, as it defines a register that was previously not defined or writeable. Changes from V1: - Updated cover letter to note that the MFD updates are build dependencies. - Removed patch for "power: supply: axp20x_battery: Fix fault handling for AXP717" as it has already been accepted upstream. - Simplified binding documentation with a "not" statement. - Corrected writeable regs in MFD driver. - Updated comment in driver to note a correctly defined device tree with a simple-battery node is required to apply the thermistor fix.
