Pull more RISC-V updates from Paul Walmsley: - Support for the RISC-V-standardized RPMI interface. RPMI is a platform management communication mechanism between OSes running on application processors, and a remote platform management processor. Similar to ARM SCMI, TI SCI, etc. This includes irqchip, mailbox, and clk changes. - Support for the RISC-V-standardized MPXY SBI extension. MPXY is a RISC-V-specific standard implementing a shared memory mailbox between S-mode operating systems (e.g., Linux) and M-mode firmware (e.g., OpenSBI). It is part of this PR since one of its use cases is to enable M-mode firmware to act as a single RPMI client for all RPMI activity on a core (including S-mode RPMI activity). Includes a mailbox driver. - Some ACPI-related updates to enable the use of RPMI and MPXY. - The addition of Linux-wide memcpy_{from,to}_le32() static inline functions, for RPMI use. - An ACPI Kconfig change to enable boot logos on any ACPI-using architecture (including RISC-V) - A RISC-V defconfig change to add GPIO keyboard and event device support, for front panel shutdown or reboot buttons * tag 'riscv-for-linus-6.18-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (26 commits) clk: COMMON_CLK_RPMI should depend on RISCV ACPI: support BGRT table on RISC-V MAINTAINERS: Add entry for RISC-V RPMI and MPXY drivers RISC-V: Enable GPIO keyboard and event device in RV64 defconfig irqchip/riscv-rpmi-sysmsi: Add ACPI support mailbox/riscv-sbi-mpxy: Add ACPI support irqchip/irq-riscv-imsic-early: Export imsic_acpi_get_fwnode() ACPI: RISC-V: Add RPMI System MSI to GSI mapping ACPI: RISC-V: Add support to update gsi range ACPI: RISC-V: Create interrupt controller list in sorted order ACPI: scan: Update honor list for RPMI System MSI ACPI: Add support for nargs_prop in acpi_fwnode_get_reference_args() ACPI: property: Refactor acpi_fwnode_get_reference_args() to support nargs_prop irqchip: Add driver for the RPMI system MSI service group dt-bindings: Add RPMI system MSI interrupt controller bindings dt-bindings: Add RPMI system MSI message proxy bindings clk: Add clock driver for the RISC-V RPMI clock service group dt-bindings: clock: Add RPMI clock service controller bindings dt-bindings: clock: Add RPMI clock service message proxy bindings mailbox: Add RISC-V SBI message proxy (MPXY) based mailbox driver ...

Pull MFD updates from Lee Jones: "This round of updates contains a fair amount of new device support, a couple of fixes and some refactoring. The most notable additions include new drivers for Loongson's Security Engine, RNG and TPM, new drivers for TI's TPS6594 Power Button and BQ257xx Charger ICs. The rest of the set provides a return value check fix and a refactoring to use a more modern GPIO API for the VEXPRESS sysreg driver, the removal of a deprecated IRQ ACK function from the MC13xxx RTC driver and a new DT binding for the aforementioned TI BQ257xx charger. New Support & Features: - Add a suite of drivers for the Loongson Security Engine, including the core controller, a Random Number Generator (RNG) and Trusted Platform Module (TPM) support. - Introduce support for the TI TPS6594 PMIC's power button, including the input driver, MFD cell registration, and a system power-off handler. - Add comprehensive support for the TI BQ257xx series of charger ICs, including the core MFD driver and a power supply driver for the charger functionality. Improvements & Fixes: - Check the return value of devm_gpiochip_add_data() in the VEXPRESS sysreg driver to prevent potential silent failures. Cleanups & Refactoring: - Add a MAINTAINERS entry for the new Loongson Security Engine drivers. - Convert the VEXPRESS sysreg driver to use the modern generic GPIO chip API.

dt-bindings: mfd: Move embedded controllers to own directory

2025-10-01T09:28:27+00:00

Move several embedded controller bindings (like ChromeOS EC, Gateworks System Controller and Kontron sl28cpld Board Management) to new subdirectory "embedded-controller" matching their purpose. An embedded controller (EC) is a discrete component that contains a microcontroller (i.e. a small CPU running a small firmware without operating system) mounted into a larger computer system running a fully fledged operating system that needs to utilize the embedded controller as part of its operation. So far the EC bindings were split between "mfd" and "platform" directory. MFD name comes from Linux, not hardware, and "platform" is a bit too generic. Rename Gateworks GSC and Huawei Gaokun filenames to match compatible, as preferred for bindings.
