[v6] Add initial support for Qualcomm SM7250 SoC

[PATCH v6 00/13] Add initial support for Qualcomm SM7250 SoC

Posted by Sreeshankar K 1 month ago

This patchset introduces foundational upstream support for the Qualcomm SM7250
SoC (internally codenamed Lito).

SM7250 is an ARMv8.2-A platform manufactured on a 7nm process, featuring an
octa-core Kryo 475 CPU configuration (1x Prime Cortex-A76, 1x Gold Cortex-A76,
and 6x Silver Cortex-A55) and Adreno 620 GPU.

This patchset is organized as follows:
> Document relevant device tree bindings (SoC ID, Kryo 475 CPUs, SCM, PDC,
RPMh clocks/power domains, GCC and cpufreq hardware).
> Add driver support for SM7250 in socinfo, rpmh-clk, rpmhpd, and GCC.
> Add the base SoC DTSI (sm7250.dtsi) defining the cpus, PSCI,
interrupt controllers, clock providers, power domains, and reserved memory.

Dependencies:
This patchset depends on the following patch:
