In terms of power, the device has PMA8084, MAX77826 (pure PMIC for
touchpad, camera, other peripherals), MAX77804k (MFD with fuel gauge,
charger, a few regulators + other). I'm sending a MAX77826 patch
shortly :)

In terms of GPIO controllers, PMA8084 has some pins, and the SoC
itself (qcom,msm8974-pinctrl) has gpio pins.

According to ./drivers/platform/msm/qpnp-revid.c from downstream,
these devices are covered by similar drivers: "PM8941", "PM8841",
"PM8019", "PM8226", "PM8110", "PMA8084", "PMI8962", "PMD9635", and my
KLTE prints the PMA8084, after querying the hardware.

I still don't have the full picture yet, but I'm pretty confident
there is no PM8941/PM8841 on the klte.
