Subject: [PATCH v10 0/6] Add interconnect driver for IPQ9574 SoC
Date: Mon, 29 Apr 2024 14:43:08 +0530 [thread overview]
Message-ID: <20240429091314.761900-1-quic_varada@quicinc.com> (raw)
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.
---
v10: Set gcc-ipq9574 driver's sync_state to icc_sync_state
v9: Squash icc-clk driver change and cbf-msm8996 change
Remove HWS_DATA macro
v8: Change icc-clk driver to take master and slave ids instead
of auto generating
Remove ICC_xxx defines from dt-bindings header
Define MASTER/SLAVE_xxx macros from 0 .. n
v7: Fix macro names in dt-bindings header
Do clock get in icc driver
v6: Removed 'Reviewed-by: Krzysztof' from dt-bindings patch
Remove clock get from ICC driver as suggested by Stephen Boyd
so that the actual peripheral can do the clock get
first_id -> icc_first_node_id
Remove tristate from INTERCONNECT_CLK
v5:
Split gcc-ipq9574.c and common.c changes into separate patches
Introduce devm_icc_clk_register
Fix error handling
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
