[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.

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The board-specific `&remoteproc_soccp` node is missing the `status = "okay";` property, relying on a flawed default in the base device tree.

commit 499497fe00069ecefb1bec759006b9907810f4e3
Author: Jingyi Wang <jingyi.wang@oss.qualcomm.com>

arm64: dts: qcom: kaanapali-qrd: Add SoCCP node

This commit adds the remote processor firmware configuration for the SoCCP
node on the Kaanapali QRD board.

[Severity: Medium]
Should this node explicitly include a status = "okay"; property?

While the node might currently function if the base kaanapali.dtsi omitted
a status = "disabled"; declaration, standard Qualcomm remoteproc conventions
typically disable remote processors by default in the base device tree.

If the base device tree is later corrected to follow this convention, the
SoCCP could silently become disabled on this board because it lacks an
explicit enable here.
