[PATCH v2 1/3] arm64: dts: qcom: sm8250-xiaomi-pipa: Drop nonexistent pm8009 pmic

[Arseniy Velikanov]

PM8009 was erroneously added since this device doesn't actually have it.
It triggers a big critical error at boot, so we're drop it.

[PATCH v2 2/3] arm64: dts: qcom: sm8250-xiaomi-pipa: Drop unused bq27z561

[Arseniy Velikanov]

It looks like the fuel gauge is not connected to the battery,
it reports nonsense info. Downstream kernel uses pmic fg.

Added max design microvolt. Merged battery info into one node,
since pmic fuel-gauge uses mixed info about dual-cell battery.

If you have to repost the patches for any reason, please sched more
light on the 'nosense' you are observing.

Since it's actually onboard, it would be fair to assume it's there
for a reason.. Does it also report nonsense when running a
downstream build?

Well, as I said before (looks like i sent reply wrongly), it's disabled
in the vendor's kernel config:
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/blob/pipa-t-oss/arch/arm64/configs/vendor/pipa_user_defconfig#L413

Also, pmic fuel gauge, which works with the WIP driver in our
close-to-mainline fork reports mixed information for a dual-cell
battery, instead of each cell individually, and I think
this is a more right way.
