X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=89f6e0251d3a84aef8380f03009ac1bf182ec206;p=users%2Fwilly%2Fxarray.git

arm64: dts: qcom: Add PM8937 PMIC

The PM8937 features integrated peripherals like ADC, GPIO controller,
MPPs, PON keys and others.

Add the device tree so that any boards with this PMIC can use it.
