The first board to use this functionality is iEi Puzzle-M801 1U Rackmount Network Appliance and is since v4 sent separately, as a standalone patch. Changes for v2: - Use LAAs for local-mac-address and match reg values - Code styling changes - Error handling moved to the end of the function - Define all magic numbers in the main header file - Convert the driver to make it OF independent - Refactor hwmon to use devm_hwmon_device_register_with_info() - Reduce the number of mutex locks - Allocate memory once for the response buffer - Reduce managed memory allocations Changes for v3: - Move iei-wt61p803-puzzle driver sysfs interface documentation to testing - Change some internal functions to static - Sync dt-bindings examples with the iEi Puzzle-M801 board dts - Remove obsolete device tree properties and correct LED functions - Reverse christmas tree variable declaration order, where possible - MAC address sysfs function rewrite - Fixed struct members size, where reasonable (MFD driver) - Add an error check for hwmon_dev - Use devm_led_classdev_register_ext() in the LED driver Changes for v4: - Clean up sensible checks reported by checkpatch --strict - Document the mutex lock usage in the LED driver - Fix error handling and code styling issues in the HWMON driver - Break up the patchset and send the iEi Puzzle-M801 board support patch separately Changes for v5: - Remove the return before goto to also fwnode_handle_put(child) when ret is 0 (LED driver) - Change unsigned char arrays to static where applicable - Fix unconventional line indentations - Remove unnecessary checks in the HWMON driver - Remove unnecessary type casts - Clear up command array assignments, where the command array is modified before it is sent - Resolve a checksum calculation issue - Add Luka Perkov to MAINTAINERS Changes for v6: - Use the container_of() macro to get the led_cdev parent struct - Use %u instead of %lu in a printf() (LED driver) Luka Kovacic (6): dt-bindings: Add iEi vendor prefix and iEi WT61P803 PUZZLE driver bindings drivers: mfd: Add a driver for iEi WT61P803 PUZZLE MCU drivers: hwmon: Add the iEi WT61P803 PUZZLE HWMON driver drivers: leds: Add the iEi WT61P803 PUZZLE LED driver Documentation/ABI: Add iei-wt61p803-puzzle driver sysfs interface documentation MAINTAINERS: Add an entry for the iEi WT61P803 PUZZLE driver .../testing/sysfs-driver-iei-wt61p803-puzzle | 55 + .../hwmon/iei,wt61p803-puzzle-hwmon.yaml | 41 + .../leds/iei,wt61p803-puzzle-leds.yaml | 45 + .../bindings/mfd/iei,wt61p803-puzzle.yaml | 82 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + MAINTAINERS | 14 + drivers/hwmon/Kconfig | 8 + drivers/hwmon/Makefile | 1 + drivers/hwmon/iei-wt61p803-puzzle-hwmon.c | 410 +++++++ drivers/leds/Kconfig | 8 + drivers/leds/Makefile | 1 + drivers/leds/leds-iei-wt61p803-puzzle.c | 147 +++ drivers/mfd/Kconfig | 8 + drivers/mfd/Makefile | 1 + drivers/mfd/iei-wt61p803-puzzle.c | 1043 +++++++++++++++++ include/linux/mfd/iei-wt61p803-puzzle.h | 66 ++ 16 files changed, 1932 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-driver-iei-wt61p803-puzzle create mode 100644 Documentation/devicetree/bindings/hwmon/iei,wt61p803-puzzle-hwmon.yaml create mode 100644 Documentation/devicetree/bindings/leds/iei,wt61p803-puzzle-leds.yaml create mode 100644 Documentation/devicetree/bindings/mfd/iei,wt61p803-puzzle.yaml create mode 100644 drivers/hwmon/iei-wt61p803-puzzle-hwmon.c create mode 100644 drivers/leds/leds-iei-wt61p803-puzzle.c create mode 100644 drivers/mfd/iei-wt61p803-puzzle.c create mode 100644 include/linux/mfd/iei-wt61p803-puzzle.h
