Hi ARM SoC Team, Please pull ! The pinctrl changes are acked and agreed to via SoC tree by Linus Walleij and the dt-bindings are acked by Rob H. Regards, Sudeep -->8 The following changes since commit 4cece764965020c22cff7665b18a012006359095: Linux 6.9-rc1 (2024-03-24 14:10:05 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux.git tags/scmi-updates-6.10 for you to fetch changes up to eb524cb651b794f2529e36deb6b18523adc9ecaa: pinctrl: Implementation of the generic scmi-pinctrl driver (2024-04-19 15:17:37 +0100) ---------------------------------------------------------------- Arm SCMI updates for v6.10 1. Basic support for SCMI v3.2 pincontrol protocol SCMI v3.2 introduces pincontrol protocol which is intended for controlling pins and their configuration. The pin control protocol provides commands to: - List the pins, groups of pins, available functions, and their association with each other. - Set the parameter configuration and multiplexing of the pins or groups of pins - Optionally request exclusive access to a pin or group of pins. - Optionally configure the permissions of an agent to access a pin or group of pins. These changes adds basic support for the same in the SCMI core layer and an implementation of the generic scmi-pinctrl driver with associated DT bindings. 2. Framework support for multiple vendors custom protocols With the fixed space for vendor protocols, the possibility of having multiple vendors implementing distinct SCMI vendor protocols with the same overlapping protocol number is very high and with the need to support them all in a single kernel image or a module is also high. In order to implement the same we assume: - vendor protocols has to be tagged at build time with a vendor_id - vendor protocols could also optionally be tagged at build time with sub_vendor_id and implementation version At the initialisation all the built vendor protocols are registered with the SCMI core using a key derived from the above tags 3. Logging and tracing improvements This includes using dev_err_probe() to bail out from probe, adding message dump traces for bad and unexpected replies and widening of the tag buffer in trace_scmi_dump_msg to allow diverse tag names 4. Miscellaneous updates or improvements This includes adding the accessor function get_max_msg_size() used in pinctl protocol, updation of dt-bindings examples for protocol@13 to promote new bindings and simplification of scmi_devm_notifier_unregister ---------------------------------------------------------------- Arnd Bergmann (1): firmware: arm_scmi: Avoid non-constant printk format strings Cristian Marussi (6): include: trace: Widen the tag buffer in trace_scmi_dump_msg firmware: arm_scmi: Add helper to trace bad messages firmware: arm_scmi: Add message dump traces for bad and unexpected replies firmware: arm_scmi: Simplify scmi_devm_notifier_unregister firmware: arm_scmi: Use dev_err_probe to bail out firmware: arm_scmi: Add support for multiple vendors custom protocols Peng Fan (5): firmware: arm_scmi: Log the perf domain names in the error paths firmware: arm_scmi: Introduce get_max_msg_size() helper/accessor dt-bindings: firmware: Support SCMI pinctrl protocol firmware: arm_scmi: Add basic support for SCMI v3.2 pincontrol protocol pinctrl: Implementation of the generic scmi-pinctrl driver Ulf Hansson (1): dt-bindings: firmware: arm,scmi: Update examples for protocol@13 .../devicetree/bindings/firmware/arm,scmi.yaml | 54 +- MAINTAINERS | 1 + drivers/firmware/arm_scmi/Makefile | 3 +- drivers/firmware/arm_scmi/common.h | 11 + drivers/firmware/arm_scmi/driver.c | 269 +++++- drivers/firmware/arm_scmi/mailbox.c | 3 + drivers/firmware/arm_scmi/notify.c | 30 +- drivers/firmware/arm_scmi/perf.c | 15 +- drivers/firmware/arm_scmi/pinctrl.c | 916 +++++++++++++++++++++ drivers/firmware/arm_scmi/protocols.h | 18 + drivers/pinctrl/Kconfig | 11 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-scmi.c | 571 +++++++++++++ include/linux/scmi_protocol.h | 86 +- include/trace/events/scmi.h | 6 +- 15 files changed, 1925 insertions(+), 70 deletions(-) create mode 100644 drivers/firmware/arm_scmi/pinctrl.c create mode 100644 drivers/pinctrl/pinctrl-scmi.c
