Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The `tlmm` (pinctrl) node is missing the `wakeup-parent = <&pdc>;` property, which breaks GPIO-based system wakeup from deep sleep.

ARM: dts: qcom: Add initial device tree for Kuno SoC

This commit adds the SoC-level DTSI and IDP board DTS for the Qualcomm Kuno
SoC. It brings in initial peripheral nodes including the Cortex-A7 CPU, RPMh
RSC, GCC, TLMM pin controller, and GENI UART console.

[Severity: Medium]
Is the wakeup-parent property missing from the tlmm node?

Without wakeup-parent = <&pdc>; being set here, the hierarchical IRQ routing
to the PDC won't be established. This causes a regression where GPIO-based
system wakeup from deep sleep states will not function, as interrupts
configured as wakeups will only be routed to the GIC, which is bypassed or
unpowered during sleep.
