[PATCH V2 0/5] Add APSS clock controller support for IPQ9574

[PATCH V2 0/5] Add APSS clock controller support for IPQ9574

[Devi Priya]

APSS PLL found in IPQ9574 platform is of type Huayra.
This series adds support for the APSS clock to bump the CPU frequency
above 800MHz.

This series depends on the below patch set
https://lore.kernel.org/linux-arm-msm/20230217083308.12017-1-quic_kathirav@quicinc.com/

DTS patch depends on the PCIe series
https://lore.kernel.org/linux-arm-msm/20230214164135.17039-1-quic_devipriy@quicinc.com/

[V2]:
	- Reordered the patches as suggested
	- Dropped [PATCH 6/6] clk: qcom: Fix APSS PLL and RCG Configuration
	  as it was unrelated
	- Detailed Change logs are added to the respective patches
[V1]:
https://lore.kernel.org/linux-arm-kernel/20230113143647.14961-1-quic_devipriy@quicinc.com/

[PATCH V2 1/5] dt-bindings: clock: qcom,a53pll: add IPQ9574 compatible

[Devi Priya]

IPQ9574 uses A73 PLL of type Huayra.
Add the IPQ9574 A73 compatible to A53 bindings as the PLL
properties match with that of A53

[Devi Priya]

The PLL and IPQ6018 APSS clock controller are
used on several IPQ platforms to clock the CPU.
Hence it should be enabled and built-in.
