soc/drivers Reset controller updates for v6.11 Move reset controller registration to the end in rzg2l-usbphy-ctrl, to simplify the probe error path, add a new i.MX8MP AudioMix reset driver, allow to build some drivers under COMPILE_TEST with fewer dependencies, and use the devm_clk_get_enabled convenience wrapper in meson-audio-arb. The latter causes a trivial merge conflict [1] with b99e9c096148f ("reset: meson-audio-arb: Convert to platform remove callback returning void") because I didn't manage to send that in last round.

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm FF-A driver updates for v6.11 The main addition is the split of bus and driver into distinct modules The FF-A bus module is initialized at subsys_initcall level when builtin. FF-A drivers initialization is now changed to module_init level so that pKVM ffa proxy is all setup and running in case pKVM hypervisor needs to trap and handle FF-A calls. One of the reason for not having this split from the beginning is the need to workaround the FF-A v1.0 NULL UUID. The FF-A bus layer called into FF-A driver and populated the device UUID if it matches with the driver attempting to match. Moving the workaround away from the FF-A bus layer to the FF-A core driver as a bus notifier will help to remove the dependency. * tag 'ffa-updates-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_ffa: Split bus and driver into distinct modules firmware: arm_ffa: Move the FF-A v1.0 NULL UUID workaround to bus notifier Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnd Bergmann <[email protected]>

git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/drivers Arm SCMI driver updates for v6.11 The main addition this time is the support for platform to agent(p2a also referred sometimes as notification or Rx) channel completion via interrupt driven method. Currently, the OSPM agent clears or acknowledge the receipt of the norification or delayed response by updating the flags in the shared memory region which the platform is expected to poll. On some platforms that are completely interrupt driven, the OSPM agent is expected to send a response message instead. This change adds the support for the same. Other changes include addition of a separate mailing list specific to SCMI to allow open discussions about the interface itself in addition to the kernel driver updates and support for system suspend via the platform noification used on some systems. * tag 'scmi-updates-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Add support for platform to agent channel completion dt-bindings: firmware: arm,scmi: Add support for notification completion channel firmware: arm_scmi: Add support for system suspend in power control driver MAINTAINERS: Add mailing list for SCMI drivers Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnd Bergmann <[email protected]>

Select the TrustZone memory allocator in Kconfig and create a pool of memory shareable with the TrustZone when probing the SCM driver. This will allow a gradual conversion of all relevant SCM calls to using the dedicated allocator. The policy used for the pool is "on-demand" and the initial size is 0 as - depending on the config - it's possible that no SCM calls needing to allocate memory will be called. The sizes of possible allocations also vary substiantially further warranting the "on-demand" approach.

2024-06-23firmware: qcom: add a dedicated TrustZone buffer allocatorBartosz Golaszewski6-0/+487
We have several SCM calls that require passing buffers to the TrustZone on top of the SMC core which allocates memory for calls that require more than 4 arguments. Currently every user does their own thing which leads to code duplication. Many users call dma_alloc_coherent() for every call which is terribly unperformant (speed- and size-wise). Provide a set of library functions for creating and managing pools of memory which is suitable for sharing with the TrustZone, that is: page-aligned, contiguous and non-cachable as well as provides a way of mapping of kernel virtual addresses to physical space. Make the allocator ready for extending with additional modes of operation which will allow us to support the SHM bridge safety mechanism once all users convert.

git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current This pull request fixes the paths of the dt-schema to their complete locations for the ChromeOS EC tunnel driver and the Atmel at91sam drivers. Additionally, the OpenCores driver receives a fix for an issue that dates back to version 2.6.18. Specifically, the interrupts need to be acknowledged (clearing all pending interrupts) after enabling the core.
