Hi ARM SoC Team, Note that this pull request contains changes in the OPP, pmdomain and the clock drivers. They have been acked-by the maintainers agreeing to take these changes via Arm SoC tree. Also note the OPP changes are merged into SCMI using immutable branch shared with OPP tree. Please pull ! Regards, Sudeep -->8 The following changes since commit ce9ecca0238b140b88f43859b211c9fdfd8e5b70: Linux 6.6-rc2 (2023-09-17 14:40:24 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git tags/scmi-updates-6.7 for you to fetch changes up to da405477e7670782241234ea6b4309f3224ecb63: firmware: arm_scmi: Add qcom smc/hvc transport support (2023-10-09 22:07:13 +0100) ---------------------------------------------------------------- Arm SCMI updates for v6.7 Main additions this time include: 1. SCMI v3.2 clock configuration support: This helps to retrieve the enabled state of a clock as well as allow to set OEM specific clock configurations. 2. Support for generic performance scaling(DVFS): The current SCMI DVFS support is limited to the CPUs in the kernel. This extension enables it to used for all kind of devices and not only for the CPUs. It updates the SCMI cpufreq to utilize the power domain bindings. It also adds a more generic SCMI performance domain based on the genpd framework that as be used for all the non-CPU devices. 3. Extend the generic performance scaling(DVFS) support for firmware driver OPPs: Consumer drivers for devices that are attached to the SCMI performance domain can't make use of the current OPP library to scale performance as the OPPs are firmware driven and often obtained from the firmware rather than the device tree. These changes extend the generic OPP and genpd PM domain frameworks to identify and utilise these firmware driven OPPs. 4. SCMI v3.2 clock parent support: This enables the support for discovering and changing parent clocks and extending the SCMI clk driver to use the same. 5. Qualcom SMC/HVC transport support: The Qualcomm virtual platforms require capability id in the hypervisor call to identify which doorbell to assert when supporting multiple SMC/HVC based SCMI transport channels. Extra parameter is added to support the same and the same is obtained at the fixed address in the shared memory which is initialised by the firmware. 6. Move the existing SCMI power domain driver under drivers/pmdomain Apart from the above main changes, it also include couple of minor fixes and cosmetic reworks. ---------------------------------------------------------------- Cristian Marussi (6): firmware: arm_scmi: Simplify enable/disable clock operations firmware: arm_scmi: Add clock v3.2 CONFIG_SET support firmware: arm_scmi: Add v3.2 clock CONFIG_GET support firmware: arm_scmi: Add clock .state_get support to pre-v3.2 clk: scmi: Add support for .is_enabled clk_ops firmware: arm_scmi: Add clock OEM config clock operations Nikunj Kela (2): dt-bindings: arm: Add new compatible for smc/hvc transport for SCMI firmware: arm_scmi: Add qcom smc/hvc transport support Peng Fan (2): firmware: arm_scmi: Add support for clock parents clk: scmi: Add support for clock {set,get}_parent Rob Herring (1): firmware: arm_scpi: Use device_get_match_data() Sudeep Holla (6): firmware: arm_scmi: Move power-domain driver to the pmdomain dir firmware: arm_scmi: Do not use !! on boolean when setting msg->flags firmware: arm_scmi: Rename scmi_{msg_,}clock_config_{get,set}_{2,21} Merge branch 'opp/pm-domain-scmi' of git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm into for-next/scmi/updates clk: scmi: Free scmi_clk allocated when the clocks with invalid info are skipped firmware: arm_scmi: Convert u32 to unsigned long to align with arm_smccc_1_1_invoke() Ulf Hansson (21): firmware: arm_scmi: Extend perf protocol ops to get number of domains firmware: arm_scmi: Extend perf protocol ops to get information of a domain cpufreq: scmi: Prepare to move OF parsing of domain-id to cpufreq firmware: arm_scmi: Align perf ops to use domain-id as in-parameter firmware: arm_scmi: Drop redundant ->device_domain_id() from perf ops cpufreq: scmi: Avoid one OF parsing in scmi_get_sharing_cpus() dt-bindings: arm: cpus: Add a power-domain-name for a performance-domain dt-bindings: firmware: arm,scmi: Extend bindings for protocol@13 dt-bindings: power: Clarify performance capabilities of power-domains cpufreq: scmi: Add support to parse domain-id using #power-domain-cells PM: domains: Allow genpd providers to manage OPP tables directly by its FW pmdomain: arm: Add the SCMI performance domain PM: domains: Introduce dev_pm_domain_set_performance_state() PM: domains: Implement the ->set_performance_state() callback for genpd OPP: Add dev_pm_opp_add_dynamic() to allow more flexibility OPP: Extend dev_pm_opp_data with a level OPP: Switch to use dev_pm_domain_set_performance_state() OPP: Extend support for the opp-level beyond required-opps firmware: arm_scmi: Simplify error path in scmi_dvfs_device_opps_add() firmware: arm_scmi: Specify the performance level when adding an OPP firmware: arm_scmi: Add generic OPP support to the SCMI performance domain Documentation/devicetree/bindings/arm/cpus.yaml | 4 +- .../devicetree/bindings/firmware/arm,scmi.yaml | 15 +- .../devicetree/bindings/power/power-domain.yaml | 17 +- MAINTAINERS | 1 + drivers/base/power/common.c | 21 ++ drivers/base/power/domain.c | 44 ++- drivers/clk/clk-scmi.c | 96 ++++- drivers/cpufreq/scmi-cpufreq.c | 52 ++- drivers/firmware/arm_scmi/Kconfig | 12 + drivers/firmware/arm_scmi/Makefile | 1 - drivers/firmware/arm_scmi/clock.c | 402 +++++++++++++++++++-- drivers/firmware/arm_scmi/driver.c | 1 + drivers/firmware/arm_scmi/perf.c | 112 +++--- drivers/firmware/arm_scmi/powercap.c | 4 +- drivers/firmware/arm_scmi/smc.c | 35 +- drivers/firmware/arm_scpi.c | 13 +- drivers/opp/core.c | 60 ++- drivers/opp/of.c | 10 +- drivers/opp/opp.h | 2 +- drivers/pmdomain/Makefile | 1 + drivers/pmdomain/arm/Makefile | 4 + drivers/pmdomain/arm/scmi_perf_domain.c | 184 ++++++++++ .../arm_scmi => pmdomain/arm}/scmi_pm_domain.c | 0 include/linux/pm.h | 2 + include/linux/pm_domain.h | 11 + include/linux/pm_opp.h | 31 +- include/linux/scmi_protocol.h | 43 ++- 27 files changed, 994 insertions(+), 184 deletions(-) create mode 100644 drivers/pmdomain/arm/Makefile create mode 100644 drivers/pmdomain/arm/scmi_perf_domain.c rename drivers/{firmware/arm_scmi => pmdomain/arm}/scmi_pm_domain.c (100%)
