A few more Qualcomm driver updates for v6.13 Make the Adreno driver invoke the SMMU aperture setup firmware function, which is required to allow the GPU to manage per-process page tables in some firmware versions - as an example Rb3Gen2 has no GPU without this. Add X1E Devkit to the list of devices that has functional EFI variable access through the uefisecapp. Flip the "manual slice configuration quirk" in the Qualcomm LLCC driver, as this only applies to a single platform, and introduce support for QCS8300, QCS615, SAR2130P, and SAR1130P. Lastly, add IPQ5424 and IPQ5404 to the Qualcomm socinfo driver. * tag 'qcom-drivers-for-6.13-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: soc: qcom: ice: Remove the device_link field in qcom_ice drm/msm/adreno: Setup SMMU aparture for per-process page table firmware: qcom: scm: Introduce CP_SMMU_APERTURE_ID soc: qcom: socinfo: add IPQ5424/IPQ5404 SoC ID dt-bindings: arm: qcom,ids: add SoC ID for IPQ5424/IPQ5404 soc: qcom: llcc: Flip the manual slice configuration condition dt-bindings: firmware: qcom,scm: Document sm8750 SCM firmware: qcom: uefisecapp: Allow X1E Devkit devices soc: qcom: llcc: Add LLCC configuration for the QCS8300 platform dt-bindings: cache: qcom,llcc: Document the QCS8300 LLCC soc: qcom: llcc: Add configuration data for QCS615 dt-bindings: cache: qcom,llcc: Document the QCS615 LLCC soc: qcom: llcc: add support for SAR2130P and SAR1130P soc: qcom: llcc: use deciman integers for bit shift values dt-bindings: cache: qcom,llcc: document SAR2130P and SAR1130P Link: https://lore.kernel.org/r/20241113032425.356306-1-andersson@kernel.org Signed-off-by: Arnd Bergmann

Arm SCMI updates for v6.13 Just couple of main additions: 1. Support for variable I/O width within ARM SCMI shared memory area. Some shared memory areas might only support a certain access width, such as 32-bit, which memcpy_{from,to}_io() does not adhere to at least on ARM64 by making both 8-bit and 64-bit accesses to such memory. This support updates the shmem layer to support reading from and writing to such shared memory area using the specified I/O width in the Device Tree. The various transport layers making use of the shmem.c code are updated accordingly to pass the I/O accessors that they store. The device tree bindings are also updated for the same. 2. Extension of SCMI transport bindings to add more properties SCMI transports are characterized by a number of properties. The values assumed by some of them tightly depend on the choices taken at design time and on the overall archiecture of the specific platform: things like timeouts, maximum message size and number of in-flight messages are closely tied to the architecture of the platform like number of SCMI agents on the system, physical memory available to the SCMI platform and so on. Such details are not discoverable as they are outside the scope of the SCMI protocol specification. Currently such properties are simple default values defined at build time, but the increasing number and variety of platforms using SCMI with a wide range of designs has increased the need to have a way to describe such properties across all these platforms. Apart from the above two, there is one NULL pointer dereference fix for very age old SCPI protocol driver which seems to be still in use on few platforms. * tag 'scmi-updates-6.13' of https://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: firmware: arm_scpi: Check the DVFS OPP count returned by the firmware firmware: arm_scmi: Relocate atomic_threshold to scmi_desc firmware: arm_scmi: Use max_msg and max_msg_size devicetree properties dt-bindings: firmware: arm,scmi: Introduce more transport properties firmware: arm_scmi: Calculate virtio PDU max size dynamically firmware: arm_scmi: Account for SHMEM memory overhead firmware: arm_scmi: Support 'reg-io-width' property for shared memory dt-bindings: sram: Document reg-io-width property firmware: arm_scmi: Use vendor string in max-rx-timeout-ms dt-bindings: firmware: arm,scmi: Add missing vendor string firmware: arm_scmi: Reject clear channel request on A2P firmware: arm_scmi: Fix slab-use-after-free in scmi_bus_notifier() Link: https://lore.kernel.org/r/20241106110727.4007489-1-sudeep.holla@arm.com Signed-off-by: Arnd Bergmann
