Driver obtains LED devices according to system configuration and creates
devices in form: "devicename:color:function", like
The full path is to be:
/sys/class/leds/mlxreg\:status\:amber/brightness
After timer trigger activation:
echo timer > /sys/class/leds/mlxreg\:status\:amber/trigger
Attributes for LED blinking will appaer in sysfs infrastructure:
/sys/class/leds/mlxreg\:status\:amber/delay_off
/sys/class/leds/mlxreg\:status\:amber/delay_on

LED setting is controlled through the on-board programmable devices,
which exports its register map. This device could be attached to any
bus type, for which register mapping is supported.

v6->v7
 Comments pointed out by Jacek:
  - Fix text in Kconfig;
v5->v6
 Changes added by Vadim:
  - Change year to 2018 in Copyright;
  - Change structure mlxreg_core_led_platform_data name to common name
    mlxreg_core_platform_data, as it has been pushed to
    git://git.infradead.org/linux-platform-drivers-x86.git to branch,
    commit 1f976f6978bf6156ce822eb279ac86c519b10329 (1f976f6), file
    include/linux/platform_data/mlxreg.h
  - Add orange color, as alternative to red (some systems use orange,
    instead of red);
  - Drop mlxreg_led_dt_match, since the driver is to be activated by another
    common Mellanox platform driver, mlx-platform or mlx-platform-of;
v4->v5
 Comments pointed out by Jacek:
 - Make consistent naming in mlxreg_led_brightness_set,
   mlxreg_led_brightness_get, mlxreg_led_config;
 - Remove unnecessary data assignment in mlxreg_led_config;
 Changes added by Vadim:
 - Add internal structure mlxreg_led_data to leds-mlxreg.c;
v3->v4
 Comments pointed out by Jacek:
 - add led in declaration mlxreg_led_store_hw and mlxreg_led_get_hw;
 - rearrange local variables names in mlxreg_led_config;
 Comments pointed out by Pavel:
 - replace _HALF/_FULL with BLINK_3HZ/BLINK_6HZ;
 - in mlxreg_led_get_hw just return after access error;
 - explicit check for green led is not added, since control device can be
   programmed for blue LED and this case it reuses masks of green LED.
v2->v3:
 Comments pointed out by Jacek:
 - fix order in includes;
 - add declaration pdata in mlxreg_led_store_hw and mlxreg_led_get_hw;
 - add declaration of led_data in mlxreg_led_config;
 - use LED_ON in assignment instead of 1;
 - fix mutex call in mlxreg_led_remove;
v1->v2:
 Comments pointed out by Jacek:
 - remove macros MLXREG_MAP and MLXREG_CDEV;
 - brightness_set_blocking insteaf of brightness_set, this fix allows
   removing of context validation and workqueue and also three fields from
   struct mlxreg_core_led_data in mlxreg.h;
 - remove MLXREG_LED_NAME;
 - extend Kconfig description;
 Changes added by Vadim:
 - remove unnecessary includes after dropping workqueue;
