This patch series depends on below patch series:
"[PATCH v2 0/4] clk: qcom: Add support for GCC and RPMHCC on SM4450"
https://lore.kernel.org/linux-arm-msm/20230909123431.1725728-1-quic_ajipan@quicinc.com/
"[PATCH v3 0/2] pinctl: qcom: Add SM4450 pinctrl driver"
https://lore.kernel.org/linux-arm-msm/20230920064739.12562-1-quic_tengfan@quicinc.com/

v2 -> v3:
  - fix dtbs_check warning
  - remove interconnect, iommu, scm and tcsr related code
  - rearrangement dt node
  - remove smmu, scm and tcsr related documentation update
  - enable CONFIG_SM_GCC_4450 in defconfig related patch

v1 -> v2:
  - setting "qcom,rpmh-rsc" compatible to the first property
  - keep order by unit address
  - move tlmm node into soc node
  - update arm,smmu.yaml
  - add enable pinctrl and interconnect defconfig patches
  - remove blank line
  - redo dtbs_check check

The SoC change must be separate from the board change.

Please leave a comment explaining what these GPIOs are

Totally unrelated change, fix the patch introducing it instead.

I checked these gpio setting, the gpio0 ~ gpio3 are for NFC eSE SPI, 
gpio136 is for LPI Debug.

[PATCH v3 5/5] arm64: defconfig: enable clock controller and pinctrl for SM4450

[Tengfei Fan]

Enable global clock controller and pinctrl for support the Qualcomm
SM4450 platform to boot to UART console.

The serial engine depends on some global clock controller and pinctrl, but
as the serial console driver is only available as built-in, so the global
clock controller and pinctrl also needs be built-in for the UART device to
probe and register the console.
