These usually add support for additional chip variations in existing drivers, but also add features or bugfixes. The SCMI firmware subsystem gains a unified raw userspace interface through debugfs, which can be used for validation purposes. Newly added drivers include: - New power management drivers for StarFive JH7110, Allwinner D1 and Renesas RZ/V2M - A driver for Qualcomm battery and power supply status - A SoC device driver for identifying Nuvoton WPCM450 chips - A regulator coupler driver for Mediatek MT81xxv"* tag 'soc-drivers-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (165 commits) power: supply: Introduce Qualcomm PMIC GLINK power supply soc: apple: rtkit: Do not copy the reg state structure to the stack soc: sunxi: SUN20I_PPU should depend on PM memory: renesas-rpc-if: Remove redundant division of dummy soc: qcom: socinfo: Add IDs for IPQ5332 and its variant dt-bindings: arm: qcom,ids: Add IDs for IPQ5332 and its variant dt-bindings: power: qcom,rpmpd: add RPMH_REGULATOR_LEVEL_LOW_SVS_L1 firmware: qcom_scm: Move qcom_scm.h to include/linux/firmware/qcom/ MAINTAINERS: Update qcom CPR maintainer entry dt-bindings: firmware: document Qualcomm SM8550 SCM dt-bindings: firmware: qcom,scm: add qcom,scm-sa8775p compatible soc: qcom: socinfo: Add Soc IDs for IPQ8064 and variants dt-bindings: arm: qcom,ids: Add Soc IDs for IPQ8064 and variants soc: qcom: socinfo: Add support for new field in revision 17 soc: qcom: smd-rpm: Add IPQ9574 compatible soc: qcom: pmic_glink: remove redundant calculation of svid soc: qcom: stats: Populate all subsystem debugfs files dt-bindings: soc: qcom,rpmh-rsc: Update to allow for generic nodes soc: qcom: pmic_glink: add CONFIG_NET/CONFIG_OF dependencies soc: qcom: pmic_glink: Introduce altmode support ...

Merge tag 'scmi-updates-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into soc/driversArm SCMI updates for v6.3The main addition is a unified userspace interface for SCMI irrespectiveof the underlying transport and along with some changed to refactor theSCMI stack probing sequence.1. SCMI unified userspace interface This is to have a unified way of testing an SCMI platform firmware implementation for compliance, fuzzing etc., from the perspective of the non-secure OSPM irrespective of the underlying transport supporting SCMI. It is just for testing/development and not a feature intended fo use in production. Currently an SCMI Compliance Suite[1] can only work by injecting SCMI messages using the mailbox test driver only which makes it transport specific and can't be used with any other transport like virtio, smc/hvc, optee, etc. Also the shared memory can be transport specific and it is better to even abstract/hide those details while providing the userspace access. So in order to scale with any transport, we need a unified interface for the same. In order to achieve that, SCMI "raw mode support" is being added through debugfs which is more configurable as well. A userspace application can inject bare SCMI binary messages into the SCMI core stack; such messages will be routed by the SCMI regular kernel stack to the backend platform firmware using the configured transport transparently. This eliminates the to know about the specific underlying transport internals that will be taken care of by the SCMI core stack itself. Further no additional changes needed in the device tree like in the mailbox-test driver.[1] https://gitlab.arm.com/tests/scmi-tests2. Refactoring of the SCMI stack probing sequence On some platforms, SCMI transport can be provide by OPTEE/TEE which introduces certain dependency in the probe ordering. In order to address the same, the SCMI bus is split into its own module which continues to be initialized at subsys_initcall, while the SCMI core stack, including its various transport backends (like optee, mailbox, virtio, smc), is now moved into a separate module at module_init level. This allows the other possibly dependent subsystems to register and/or access SCMI bus well before the core SCMI stack and its dependent transport backends.* tag 'scmi-updates-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux: (31 commits) firmware: arm_scmi: Clarify raw per-channel ABI documentation firmware: arm_scmi: Add per-channel raw injection support firmware: arm_scmi: Add the raw mode co-existence support firmware: arm_scmi: Call raw mode hooks from the core stack firmware: arm_scmi: Reject SCMI drivers when configured in raw mode firmware: arm_scmi: Add debugfs ABI documentation for raw mode firmware: arm_scmi: Add core raw transmission support firmware: arm_scmi: Add debugfs ABI documentation for common entries firmware: arm_scmi: Populate a common SCMI debugfs root debugfs: Export debugfs_create_str symbol include: trace: Add platform and channel instance references firmware: arm_scmi: Add internal platform/channel identifiers firmware: arm_scmi: Move errors defs and code to common.h firmware: arm_scmi: Add xfer helpers to provide raw access firmware: arm_scmi: Add flags field to xfer firmware: arm_scmi: Refactor scmi_wait_for_message_response firmware: arm_scmi: Refactor polling helpers firmware: arm_scmi: Refactor xfer in-flight registration routines firmware: arm_scmi: Split bus and driver into distinct modules firmware: arm_scmi: Introduce a new lifecycle for protocol devices ...Link: https://lore.kernel.org/r/20230120162152.1438456-1-sudeep.holla@arm.comSigned-off-by: Arnd Bergmann List of files: /linux/Documentation/ABI/testing/debugfs-scmi
