Subject: [GIT PULL] firmware: arm_scmi: Updates for v6.7
Date: Tue, 10 Oct 2023 13:43:47 +0100 [thread overview]
Message-ID: <20231010124347.1620040-1-sudeep.holla@arm.com> (raw)
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 !

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.
