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 v4 0/2] pinctl: qcom: Add SM4450 pinctrl driver"
https://lore.kernel.org/linux-arm-msm/20230920082102.5744-1-quic_tengfan@quicinc.com/

v4 -> v5:
  - separate reserved gpios setting from enable UART console patch

v3 -> v4:
  - adjustment the sequence of property and property-names
  - update 0 to 0x0 for reg params
  - remove unrelated change
  - separate SoC change and board change

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

[PATCH v5 7/7] arm64: defconfig: enable clock controller and pinctrl

[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.
