Hi, I've been looking into AXP223 usage as part of the RSB patches. I found that the recommended voltage for VDD-SYS is 1.1V, but we default to 1.2V in U-boot. Among the fex files, some use 1.1V and some use 1.2V.
Perhaps we could update the defconfigs with the values from the fex files. One thing that we have to be careful of is matching the settings in U-boot and the kernel, or alternatively, not use a fixed value but the recommended range for the VDD-SYS regulator. Accidentally dropping the voltage on VDD-SYS results in some logic errors, which likely lead to a crash.
