[PATCH v3 0/3] Add interconnect driver for IPQ9574 SoC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



MSM platforms manage NoC related clocks and scaling from RPM.
However, in IPQ SoCs, RPM is not involved in managing NoC
related clocks and there is no NoC scaling.

However, there is a requirement to enable some NoC interface
clocks for the accessing the peripherals present in the
system. Hence add a minimalistic interconnect driver that
establishes a path from the processor/memory to those peripherals
and vice versa.

v4:
gcc-ipq9574.c
	Use clk_hw instead of indices
common.c
	Do icc register in qcom_cc_probe() call stream
common.h
	Add icc clock info to qcom_cc_desc structure

v3:
qcom,ipq9574.h
	Move 'first id' define to clock driver
gcc-ipq9574.c:
	Use indexed identifiers here to avoid confusion
	Fix error messages and move code to common.c as it can be
	shared with future SoCs

v2:
qcom,ipq9574.h
	Fix license identifier
	Rename macros
qcom,ipq9574-gcc.yaml
	Include interconnect-cells
gcc-ipq9574.c
	Update commit log
	Remove IS_ENABLED(CONFIG_INTERCONNECT) and auto select it from Kconfig
ipq9574.dtsi
	Moved to separate patch
	Include interconnect-cells to clock controller node
drivers/clk/qcom/Kconfig:
	Auto select CONFIG_INTERCONNECT & CONFIG_INTERCONNECT_CLK
