[PATCH v2 0/3] arm64: dts: qcom: kaanapali: Add SoCCP

[Jingyi Wang]

Add device tree support for SoCCP on Kaanapali platform. The SoC Control
Processor (SoCCP) is small RISC-V MCU that controls USB Type-C, battery
charging and various other functions on Qualcomm SoCs. On Kaanapali,
SoCCP is brought up by bootloader by default.
