CPU on Qualcomm ipq5424 is clocked by huayra PLL with RCG support.
Add support for the APSS PLL, RCG and clock enable for ipq5424.
The PLL, RCG register space are clubbed. Hence adding new APSS driver
for both PLL and RCG/CBC control. Also the L3 cache has a separate pll
modeled as ICC clock. The L3 pll needs to be scaled along with the CPU.
v7: Fix 'Reviewed-by' placement for bindings patch
Use enum instead of clock names for l3 pll
Select IPQ_APSS_5424 if IPQ_GCC_5424 is enabled
v6: https://lore.kernel.org/linux-arm-msm/20250806112807.2726890-1-quic_varada@quicinc.com/
* Drop clock-names in bindings, dts and driver and use index instead
* Fix 'opp-microvolt'
v5: https://lore.kernel.org/linux-arm-msm/20250804112041.845135-1-quic_varada@quicinc.com/
* Remove previous maintainers from bindings file
* Use enums instead of clock names in clock struct
* Add '.sync_state = icc_sync_state'
* Add opp-816000000
v4: https://lore.kernel.org/linux-arm-msm/20250730081316.547796-1-quic_varada@quicinc.com/
* Address bindings related comments
v3: https://lore.kernel.org/linux-arm-msm/20250724102540.3762358-1-quic_varada@quicinc.com/
* Use the qcom_cc_driver_data framework to trim down apss_ipq5424_probe
v2: https://lore.kernel.org/linux-arm-msm/20250723110815.2865403-1-quic_varada@quicinc.com/
* Use icc-clk framework for l3 pll
v1: https://lore.kernel.org/linux-arm-msm/20250127093128.2611247-1-quic_srichara@quicinc.com/
