power: supply: max17042: handle fails of reading status register

2021-09-18T11:43:22+00:00

commit 54784ffa5b267f57161eb8fbb811499f22a0a0bf upstream. Reading status register can fail in the interrupt handler. In such case, the regmap_read() will not store anything useful under passed 'val' variable and random stack value will be used to determine type of interrupt. Handle the regmap_read() failure to avoid handling interrupt type and triggering changed power supply event based on random stack value.

power: supply: smb347-charger: Add missing pin control activation

2021-09-15T08:02:04+00:00

[ Upstream commit efe2175478d5237949e33c84d9a722fc084b218c ] Pin control needs to be activated by setting the enable bit, otherwise hardware rejects all pin changes. Previously this stayed unnoticed on Nexus 7 because pin control was enabled by default after rebooting from downstream kernel, which uses driver that enables the bit and charger registers are non-volatile until power supply (battery) is disconnected. Configure the pin control enable bit. This fixes the potentially never-enabled charging on devices that use pin control.

kernel.h: split out panic and oops helpers

2021-07-01T18:06:04+00:00

kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

power: supply: ab8500: Fix an old bug

2021-06-29T22:14:55+00:00

Trying to get the AB8500 charging driver working I ran into a bit of bitrot: we haven't used the driver for a while so errors in refactorings won't be noticed. This one is pretty self evident: use argument to the macro or we end up with a random pointer to something else.
