Merge tag 'scmi-updates-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI updates for v6.6 The main addition this time is the support for SCMI v3.2 perf level indexing mode. SCMI v3.2 adds support for hardware which works on performance indices, instead of levels. Certain platforms use indices to identify performance levels. Level Indexing Mode is used to describe such platform behavior. All commands which utilize performance level as a parameter need to specify the corresponding level index instead of the performance level when Level Indexing Mode is used. While at it, these changes also include hardening of all the internal accesses to the performance domain information. * tag 'scmi-updates-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Add v3.2 perf level indexing mode support firmware: arm_scmi: Harden perf domain info access Link: https://lore.kernel.org/r/20230804123231.3258141-1-sudeep.holla@arm.comSigned-off-by:

Record SCU wakeup interrupt in /sys/power/pm_wakeup_irq The user can further identify the exact wakeup source by using the following interface: cat /sys/firmware/scu_wakeup_source/wakeup_src The above will print the wake groups and the irqs that could have contributed to waking up the kernel. For example if ON/OFF button was the wakeup source: cat /sys/firmware/scu_wakeup_source/wakeup_src Wakeup source group = 3, irq = 0x1 The user can refer to the SCFW API documentation to identify all the wake groups and irqs.

Use blocking_notifier_chain instead of atomic_notifier_chain, otherwise there will be RCU complaint, because unregister/register_virtio_device() will issue mbox message. mbox_send_message() is blocking again after received M4 partition reset.

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes. Signed-off-by:
