[PATCH 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, so the status is set "okay" in the
dtsi patch.

This series is not ready for apply as the driver above is in discussion.

Simply remove it, "okay" is the default if the property is absent

This is really more of an "add firmware path"

Given that this contains battmgr now, can MTP and QRD use the same
firmware?

Offline checked with the POC for SoCCP firmware, MTP and QRD board
share the same soccp firmware.
