leds: add driver for Mellanox systems LEDs
This makes it possible to create a set of LEDs for Mellanox systems: "msx6710", "msx6720", "msb7700", "msn2700", "msx1410", "msn2410", "msb7800", "msn2740", "msn2100". Driver obtains LED devices according to system configuration, provided through system DMI data, like mlxcpld:fan1:green, mlxcpld:fan1:red and creates devices in form: "devicename:colour:function". LED setting is controlled through on board CPLD Lattice device. For setting particular LED off, solid, blink: echo 0 > /sys/class/leds/mlxcpld\:status\:green/brightness echo 1 > /sys/class/leds/mlxcpld\:status\:green/brightness echo timer > /sys/class/leds/mlxcpld\:status\:green/trigger On module probing all LEDs are set green, on removing - off. Last setting overwrites previous, f.e. sequence for changing LED from green - red - green: echo 1 > /sys/class/leds/mlxcpld\:psu\:green/brightness echo 1 > /sys/class/leds/mlxcpld\:psu\:red/brightness echo 1 > /sys/class/leds/mlxcpld\:psu\:green/brightness Note: LEDs cannot be turned on/off simultaneously. The Kconfig currently controlling compilation of this code is: drivers/leds/Kconfig:config LEDS_MLXCPLD Signed-off-by: Vadim Pasternak <vadimp@mellanox.com> Reviewed-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
