https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v6.11 Support for Shared Memory (shm) Bridge is added, which provides a stricter interface for handling of buffers passed to TrustZone. The X1Elite platform is added to uefisecapp allow list, to instantiate the efivars implementation. A new in-kernel implementation of the pd-mapper (or servreg) service is introduced, to replace the userspace dependency for USB Type-C and battery management. Support for sharing interrupts across multiple bwmon instances is added, and a refcount imbalance issue is corrected. The LLCC support for recent platforms is corrected, and SA8775P support is added. A new interface is added to SMEM, to expose "feature codes". One example of the usecase for this is to indicate to the GPU driver which frequencies are available on the given device. The interrupt consumer and provider side of SMP2P is updated to provide more useful names in interrupt stats. Support for using the mailbox binding and driver for outgoing IPC interrupt in the SMSM driver is introduced. socinfo driver learns about SDM670 and IPQ5321, as well as get some updates to the X1E PMICs. pmic_glink is bumped to now support managing 3 USB Type-C ports. * tag 'qcom-drivers-for-6.11' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (48 commits) soc: qcom: smp2p: Use devname for interrupt descriptions soc: qcom: smsm: Add missing mailbox dependency to Kconfig soc: qcom: add missing pd-mapper dependencies soc: qcom: icc-bwmon: Allow for interrupts to be shared across instances dt-bindings: interconnect: qcom,msm8998-bwmon: Add X1E80100 BWMON instances dt-bindings: interconnect: qcom,msm8998-bwmon: Remove opp-table from the required list firmware: qcom: tzmem: export devm_qcom_tzmem_pool_new() soc: qcom: add pd-mapper implementation soc: qcom: pdr: extract PDR message marshalling data soc: qcom: pdr: fix parsing of domains lists soc: qcom: pdr: protect locator_addr with the main mutex firmware: qcom: scm: clarify the comment in qcom_scm_pas_init_image() firmware: qcom: scm: add support for SHM bridge memory carveout firmware: qcom: tzmem: enable SHM Bridge support firmware: qcom: scm: add support for SHM bridge operations firmware: qcom: qseecom: convert to using the TZ allocator firmware: qcom: scm: make qcom_scm_qseecom_app_get_id() use the TZ allocator firmware: qcom: scm: make qcom_scm_lmh_dcvsh() use the TZ allocator firmware: qcom: scm: make qcom_scm_ice_set_key() use the TZ allocator firmware: qcom: scm: make qcom_scm_assign_mem() use the TZ allocator ...

Pull ARM SoC devicetree updates from Arnd Bergmann: "The biggest change this time is for the 32-bit devicetree files, which are all moved to a new location, using separate subdirectories for each SoC vendor, following the same scheme that is used on arm64, mips and riscv. This has been discussed for many years, but so far we never did this as there was a plan to move the files out of the kernel entirely, which has never happened. The impact of this will be that all external patches no longer apply, and anything depending on the location of the dtb files in the build directory will have to change. The installed files after 'make dtbs_install' keep the current location. There are six added SoCs here that are largely variants of previously added chips. Two other chips are added in a separate branch along with their device drivers. - The Samsung Exynos 4212 makes its return after the Samsung Galaxy Express phone is addded at last. The SoC support was originally added in 2012 but removed again in 2017 as it was unused at the time. - Amlogic C3 is a Cortex-A35 based smart IP camera chip - Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of the still common MSM8916 (Snapdragon 410) phone chip that has been supported for a long time. - Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end laptop chips, used in the Lenovo Flex 5G, which is added along with the reference board. - Qualcomm SDX75 is the latest generation modem chip that is used as a peripherial in phones but can also run a standalone Linux. Unlike the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55. - Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the Xuantie C910 core, a step up from all previously added rv64 chips. All of the above come with reference board implementations, those included there are 39 new board files, but only five more 32-bit this time, probably a new low: - Marantec Maveo board based on dhcor imx6ull module - Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip - Epson Moverio BT-200 AR glasses based on TI OMAP4 - PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM - ICnova ADB4006 board based on Allwinner A20 On the 64-bit side, there are also fewer addded machines than we had in the recent releases: - Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device. - NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234 - Qualcomm gains support for 6 reference boards on various members of their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top of the various reference platforms for their new chips. - Rockchips support for several newer boards: Indiedroid Nova (rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn Fastrhino R66S/R68S (rk3568) - TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex Verdin family with AM62 COM, carrier and dev boards Other changes to existing boards contain the usual minor improvements along with - continued updates to clean up dts files based on dtc warnings and binding checks, in particular cache properties and node names - support for devicetree overlays on at91, bcm283x - significant additions to existing SoC support on mediatek, qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST STM32MP1 As usual, a lot more detail is available in the individual merge commits" * tag 'soc-dt-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (926 commits) ARM: mvebu: fix unit address on armada-390-db flash ARM: dts: Move .dts files to vendor sub-directories kbuild: Support flat DTBs install ARM: dts: Add .dts files missing from the build ARM: dts: allwinner: Use quoted #include ARM: dts: lan966x: kontron-d10: add PHY interrupts ARM: dts: lan966x: kontron-d10: fix SPI CS ARM: dts: lan966x: kontron-d10: fix board reset ARM: dts: at91: Enable device-tree overlay support for AT91 boards arm: dts: Enable device-tree overlay support for AT91 boards arm64: dts: exynos: Remove clock from Exynos850 pmu_system_controller ARM: dts: at91: use generic name for shutdown controller ARM: dts: BCM5301X: Add cells sizes to PCIe nodes dt-bindings: firmware: brcm,kona-smc: convert to YAML riscv: dts: sort makefile entries by directory riscv: defconfig: enable T-HEAD SoC MAINTAINERS: add entry for T-HEAD RISC-V SoC riscv: dts: thead: add sipeed Lichee Pi 4A board device tree riscv: dts: add initial T-HEAD TH1520 SoC device tree riscv: Add the T-HEAD SoC family Kconfig option ...

Trogdor devices use firmware backed by TF-A instead of Qualcomm's normal TZ. On TF-A we end up mapping memory as cacheable. Specifically, you can see in Trogdor's TF-A code [1] in qti_sip_mem_assign() that we call qti_mmap_add_dynamic_region() with MT_RO_DATA. This translates down to MT_MEMORY instead of MT_NON_CACHEABLE or MT_DEVICE. Let's allow devices like trogdor to be described properly by allowing "dma-coherent" in the SCM node.

Support for multiple SMC/HVC transports for SCMI: Some platforms need to support multiple SCMI instances within a platform(more commonly in a VM). The same SMC/HVC FID is used with all the instances. The platform or the hypervisor needs a way to distinguish among SMC/HVC calls made from different instances. This change adds support for passing shmem channel address as the parameters in the SMC/HVC call. The address is split into 4KB-page and offset for simiplicity. 2. Addition od SCMI v3.2 explicit powercap enable/disable support: SCMI v3.2 specification introduces support to disable powercapping as a whole on the desired zones. This change adds the needed support to the core SCMI powercap protocol, exposing enable/disable protocol operations and then wiring up the new operartions in the related powercap framework helpers. * tag 'scmi-updates-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: powercap: arm_scmi: Add support for disabling powercaps on a zone firmware: arm_scmi: Add Powercap protocol enable support firmware: arm_scmi: Refactor the internal powercap get/set helpers firmware: arm_scmi: Augment SMC/HVC to allow optional parameters dt-bindings: firmware: arm,scmi: support for parameter in smc/hvc call 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 updates for v6.4 The main and only new addition this time around is the support for unidirectional mailbox channels. SCMI communicates between the agent and the platform using one bidirectional 'a2p' channel used by the agent to send SCMI commands and synchronously receive the related replies, and an optional 'p2a' unidirectional channel used to asynchronously receive delayed responses and notifications emitted from the platform. In order to support platforms that support only unidirectional mailbox hardware channels, the existing bindings are extended to support the same. Both bidirectional and unidirectional channels support for the SCMI mailbox can coexist. The correct and effective combination of defined 'mboxes' and 'shmem' descriptors determines the type of the mailbox channel. This also contains a fix for the transfers allocation on Rx channel especially when the base protocol doesn't use Rx channel while some of the protocols can have dedicated Rx channels. * tag 'scmi-updates-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scmi: Add support for unidirectional mailbox channels dt-bindings: firmware: arm,scmi: Support mailboxes unidirectional channels firmware: arm_scmi: Fix xfers allocation on Rx channel firmware: arm_scmi: Use the bitmap API to allocate bitmaps firmware: arm_scmi: Fix device node validation for mailbox transport firmware: arm_scmi: Fix raw coexistence mode behaviour on failure path firmware: arm_scmi: Remove duplicate include header inclusion firmware: arm_scmi: Return a literal instead of a variable firmware: arm_scmi: Clean up a return statement in scmi_probe Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnd Bergmann <[email protected]>

2023-04-05dt-bindings: firmware: arm,scmi: Support mailboxes unidirectional channelsCristian Marussi1-10/+38
SCMI defines two kinds of communication channels between the agent and the platform: one bidirectional 'a2p' channel used by the agent to send SCMI commands and synchronously receive the related replies, and an optional 'p2a' unidirectional channel used to asynchronously receive delayed responses and notifications emitted from the platform. When configuring an SCMI transport based on mailboxes, the current binding supports only mailboxes providing bidirectional channels: in such a case one mailbox channel can be easily assigned to each SCMI channel as above described. In case, instead, to have to deal with mailboxes providing only distinct unidirectional channels, it becomes necessary to extend the binding in order to be able to bind 2 distinct unidirectional mailbox channels to the same SCMI 'a2p' channel. Bidirectional and unidirectional channels support for the SCMI mailbox transport can coexist by carefully considering the effective combination of defined 'mboxes' and 'shmem' descriptors.
