preference=encrypt Synology uses a microcontroller in their NAS devices connected to a serial port to control certain LEDs, fan speeds, a beeper, to handle proper shutdown and restart, buttons and fan failures. This patch series depends on the rust led abstraction [1] and the rust serdev abstraction [2]. This is only a initial version of the driver able to control LEDs. The following rust abstractions would be required, to implement the remaining features: - hwmon (include/linux/hwmon.h) - input (include/linux/input.h) - sysoff handler + hardware protection shutdown (include/linux/reboot.h) [1] https://lore.kernel.org/rust-for-linux/20260207-rust_leds-v12-0-fdb518417b75@posteo.de/ [2] https://lore.kernel.org/rust-for-linux/20260306-rust_serdev-v2-0-e9b23b42b255@posteo.de/ Signed-off-by: Markus Probst --- Changes in v2: - fix missing tabs in MAINTAINERS file - remove word binding from patch subject - add missing signed-off-by - add missing help entry in Kconfig - add missing spdx license headers - remove no-check{,-cpu}-fan properties from the dt-bindings and replace them with the check_fan module parameter - use patternProperties for leds in dt-bindings - license dt-binding as GPL-2.0-only OR BSD-2-Clause - move driver from staging tree into mfd tree and mark it as work in progress inside Kconfig - only register alert and usb led if fwnode is present - Link to v1: https://lore.kernel.org/r/20260306-synology_microp_initial-v1-0-fcffede6448c@posteo.de --- Markus Probst (2): dt-bindings: mfd: Add synology,microp device mfd: Add initial synology microp driver .../devicetree/bindings/mfd/synology,microp.yaml | 49 ++++ MAINTAINERS | 6 + drivers/mfd/Kconfig | 2 + drivers/mfd/Makefile | 2 + drivers/mfd/synology_microp/Kconfig | 14 ++ drivers/mfd/synology_microp/Makefile | 2 + drivers/mfd/synology_microp/TODO | 7 + drivers/mfd/synology_microp/command.rs | 50 ++++ drivers/mfd/synology_microp/led.rs | 275 +++++++++++++++++++++ drivers/mfd/synology_microp/synology_microp.rs | 82 ++++++ rust/uapi/uapi_helper.h | 2 + 11 files changed, 491 insertions(+) --- base-commit: 9fad1d148df6f36105159c2503d0ecb1397bc89a change-id: 20260306-synology_microp_initial-0f7dac7b7496 prerequisite-change-id: 20251217-rust_serdev-ee5481e9085c:v2 prerequisite-patch-id: 52b17274481cc770c257d8f95335293eca32a2c5 prerequisite-patch-id: 680c0509490833f416b17eb3b918bb829ce7b90f prerequisite-patch-id: 37016d6c07f0da898be02bf30110e8c0a30025d2 prerequisite-patch-id: 3dfc1f7e5ecd3e0dd65d676aeb16f55260847b25 prerequisite-change-id: 20251114-rust_leds-a959f7c2f7f9:v12 prerequisite-patch-id: 42c445ef6981e3a3740dbaaf307f4b810042e46f prerequisite-patch-id: 90c7b200cca722a592353885e21af069101c4e09 prerequisite-patch-id: c664a52faa3d47000d252eb7603c9c08382e868a
