I'm sorry this happens, but I really want solve this stuff which in suspend since 2015.
So let me recall the original issue:
DTBS check reports:
arch/arm/boot/dts/qcom-mdm9615-wp8548-mangoh-green.dtb: pmic@0: compatible: ['qcom,pm8018', 'qcom,pm8921'] is too long

So trying to solve those, and since the PMIC in the wp8548 module is a PM8018, and it happens to be (partially ?? potentially ??) compatible
with the PM8921, and I had issues adding per-HW compatible for the pwrkey, the obvious solution would be to
drop the PM8921 compatibility since it's only probable and nothing proves it's right.
But what's sure: it's a PM8018 PMIC.
But since the PM8018 PWRKEY interface is compatible with the PM8921 PWRKEY interface,
it's perfectly ok to the the MP8921 compatible here.
OK, so as you quoted multiple times:
"How this should be fixed? First, drop bogus entries from drivers, then
document proper compatibles."
OK so there's no bogus entries to remove here, and the only compatible to
potentially document is the pm8018-pwrkey but it seems to be wrong.
I'll be happy to have an hint on how to handle that to I can go forward and
stop the noise, there's still plenty of stuff to fix in the MDM9615 DT.
Best regards,
Krzysztof
