Hi ARM SoC Team,
Please pull !
The clk and the cpufreq changes are acked/reviewed by maintainers and
agreed to get this merged via ARM SoC tree.
Regards,
Sudeep
v1[1]->v2:
- Remove unneeded __packed and fixed size fields as suggested by
Arnd[2]
- Add a fix for clk registration of discrete rate clocks that
was reported last week.

firmware: arm_scmi: Remove fixed size fields from reports/scmi_event_header (2020-07-13 09:40:21 +0100)
----------------------------------------------------------------
ARM SCMI/SCPI updates for v5.9
The main addition for this time is the support for platform notifications.
SCMI protocol specification allows the platform to signal events to the
interested agents via notification messages. We are adding support for
the dispatch and delivery of such notifications to the interested users
inside the kernel.
Other than that, there are minor changes like checking and using the
fast_switch capability quering the firmware instead of doing it
unconditionally(using polling mode transfer), cosmetic trace update,
use of HAVE_ARM_SMCCC_DISCOVERY instead of ARM_PSCI_FW and a fix in
scmi clock registration logic for all the clocks with discrete rates.
