mfd: ls2kbmc: Introduce Loongson-2K BMC core driver

2025-10-01T09:28:49+00:00

The Loongson-2K Board Management Controller provides an PCIe interface to the host to access the feature implemented in the BMC. The BMC is assembled on a server similar to the server machine with Loongson-3 CPU. It supports multiple sub-devices like DRM and IPMI.

mfd: Add core driver for Nuvoton NCT6694

2025-09-16T13:41:57+00:00

The Nuvoton NCT6694 provides an USB interface to the host to access its features. Sub-devices can use the USB functions nct6694_read_msg() and nct6694_write_msg() to issue a command. They can also request interrupt that will be called when the USB device receives its interrupt pipe.

mfd: Add Apple Silicon System Management Controller

2025-07-24T08:47:33+00:00

The System Management Controller (SMC) on Apple Silicon machines is a piece of hardware that exposes various functionalities such as temperature sensors, voltage/power meters, shutdown/reboot handling, GPIOs and more. Communication happens via a shared mailbox using the RTKit protocol which is also used for other co-processors. The SMC protocol then allows reading and writing many different keys which implement the various features. The MFD core device handles this protocol and exposes it to the sub-devices. Some of the sub-devices are potentially also useful on pre-M1 Apple machines and support for SMCs on these machines can be added at a later time.

mfd: sec: Merge separate core and irq modules

2025-05-23T07:48:34+00:00

There is no reason to have these two kernel modules separate. Having them merged into one kernel module also slightly reduces memory consumption and module load times a little. mapped size (lsmod): before: after: sec_core 20480 sec_core 24576 sec_irq 16384 ---------------- total 36864 Section sizes (size -A): before: after: sec_core 6780 sec_core 13239 sec_irq 8046 ---------------- Total 14826 Reviewed-by: Krzysztof Kozlowski Signed-off-by: André Draszik Link: https://lore.kernel.org/r/20250409-s2mpg10-v4-10-d66d5f39b6bf@linaro.org Signed-off-by: Lee Jones
