[PATCH 0/7] ARM: dts: qcom: Add more device coniguration nodes

[Ivan T. Ivanov]

Recent Qualcomm PMIC's devices are accessed over SPMI bus.
Every PMIC has several "sub-function" devices inside.

First three patches are adding device nodes to PM8841, PM8941 and PMA8084 PMIC's.
Next two are introducing PM8916 PMIC chip with its device nodes.
Sixth add restart device node for MSM8916 chip.
And the last one add initial GPIO definitions for APQ8016 SBC board.

All compatible drivers are already merged or will soon be merged,
hopefully in the 4.1 merge window. This is why checkpatch will complain about
"appears un-documented". checkpatch will also complain about
"line over 80 characters", but I hope that in this case this is in favor
in readability.

Patches are created top of Kumar's kernel tree and tags/qcom-dt-for-4.1 [1].

Any comments are welcome.

Regards,
Ivan

What’s the interrupt parent here with 4 cells? Can we cleanup the last cell to use proper define for level/edge etc.

[PATCH 5/7] arm64: dts: qcom: Add 8x16 chipset SPMI PMIC's nodes

[Ivan T. Ivanov]

PM9816 has 2 SPMI devices per physical package. Add PMIC configuration
nodes including sub-function device nodes and include them in boards,
which are using 8x16 based chipset.

PM9816 sub-function devices include:

* GPIO block, with 4 pins
* MPP block, with 4 pins
* Volatage ADC (VADC), with multiple inputs
* Thermal sensor device, which is using on chip VADC
  channel report PMIC die temperature.
* Power key device, which is responsible for clean system
  reboot or shutdown
* RTC device
