Hi Konrad,

Sorry for the late reply, but I wanted to look at the latest
downstream code before responding.

Sure, but the following are the latest values used in the downstream
.dtsi, so I used them in the latest version and tested with the same
on sa8115p-adp and sm8150-mtp without any issues:

qcedev:
0x0502 0x0641
0x0504 0x0011

qcom_cedev_ns_cb:
0x0506 0x0011
0x0508 0x0011
0x0512 0x0000

I dropped:
0x0514 0x0011 // equal to 0x504 0x11
0x0516 0x0011 // equal to 0x506 0x11
0x0518 0x0011 // equal to 0x508 0x11

Thanks for pointing this out.
