Pull ARM SoC driver updates from Arnd Bergmann: "The most notable updates this time are for Qualcomm Snapdragon platforms. The Inline-Crypto-Engine gets a new DT binding and driver, and a number of drivers now support additional Snapdragon variants, in particular the rsc, scm, geni, bwm, glink and socinfo, while the llcc (edac) and rpm drivers get notable functionality updates. Updates on other platforms include: - Various updates to the Mediatek mutex and mmsys drivers, including support for the Helio X10 SoC - Support for unidirectional mailbox channels in Arm SCMI firmware - Support for per cpu asynchronous notification in OP-TEE firmware - Minor updates for memory controller drivers. - Minor updates for Renesas, TI, Amlogic, Apple, Broadcom, Tegra, Allwinner, Versatile Express, Canaan, Microchip, Mediatek and i.MX SoC drivers, mainly updating the use of MODULE_LICENSE() macros and obsolete DT driver interfaces" * tag 'soc-drivers-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (165 commits) soc: ti: smartreflex: Simplify getting the opam_sr pointer bus: vexpress-config: Add explicit of_platform.h include soc: mediatek: Kconfig: Add MTK_CMDQ dependency to MTK_MMSYS memory: mtk-smi: mt8365: Add SMI Support dt-bindings: memory-controllers: mediatek,smi-larb: add mt8365 dt-bindings: memory-controllers: mediatek,smi-common: add mt8365 memory: tegra: read values from correct device dt-bindings: crypto: Add Qualcomm Inline Crypto Engine soc: qcom: Make the Qualcomm UFS/SDCC ICE a dedicated driver dt-bindings: firmware: document Qualcomm QCM2290 SCM soc: qcom: rpmh-rsc: Support RSC v3 minor versions soc: qcom: smd-rpm: Use GFP_ATOMIC in write path soc/tegra: fuse: Remove nvmem root only access soc/tegra: cbb: tegra194: Use of_address_count() helper soc/tegra: cbb: Remove MODULE_LICENSE in non-modules ARM: tegra: Remove MODULE_LICENSE in non-modules soc/tegra: flowctrl: Use devm_platform_get_and_ioremap_resource() soc: tegra: cbb: Drop empty platform remove function firmware: arm_scmi: Add support for unidirectional mailbox channels dt-bindings: firmware: arm,scmi: Support mailboxes unidirectional channels ...

memory: tegra: fix interconnect registration race

2023-03-13T19:13:48Z

The current interconnect provider registration interface is inherently racy as nodes are not added until the after adding the provider. This can specifically cause racing DT lookups to fail. Switch to using the new API where the provider is not registered until after it has been fully initialised.

memory: tegra: remove MODULE_LICENSE in non-modules

2023-03-09T14:20:46Z

Since commit 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

memory: tegra: Add API for retrieving carveout bounds

2022-11-25T15:14:58Z

On Tegra234 NVDEC firmware is loaded from a secure carveout, where it has been loaded by a bootloader. When booting NVDEC, we need to tell it the address of this firmware, which we can determine by checking the starting address of the carveout. As such, add an MC API to query the bounds of carveouts, and add related information on Tegra234. Signed-off-by: Mikko Perttunen Acked-by: Krzysztof Kozlowski Signed-off-by: Thierry Reding

memory: tegra: Add MC error logging on Tegra186 onward

2022-05-09T08:46:14Z

Add support for logging memory controller errors on Tegra186, Tegra194 and Tegra234. On these SoCs, interrupts can occur on multiple channels. Add support required to read the status of interrupts across multiple channels, log and clear them. Also add new interrupts supported on these SoCs.

memory: tegra: Add Tegra234 support

2022-05-09T08:46:00Z

The memory controller and external memory controller found on Tegra234 is similar to the version found on earlier SoCs but supports a number of new memory clients. Add initial memory client definitions for the Tegra234 so that the SMMU stream ID override registers can be properly programmed at boot time.

memory: tegra: Remove interconnect state syncing hack

2021-09-20T08:32:53Z

State syncing works properly now, previously the sync callback was never invoked. Apparently it was fixed in drivers core, so let's remove the hack. The state won't be synced until all consumer drivers of devices that reference memory controller in a device-tree are probed, i.e. keeping bandwidth at maximum until both display and devfreq drivers are probed.
