+What:		/sys/class/leds/<led>/priority
+Date:		August 2025
+Contact:	Radoslav Tsvetkov <rtsvetkov@gradotech.eu>
+Description:	(RW) Priority level of the virtual LED group. Higher numbers
+        indicate higher priority. When multiple virtual LED groups are
+        active, only the highest priority group's state will be applied
+        to the physical LEDs.
+
+        Valid values: 0 to INT_MAX
+        Default: 0
+
+What:		/sys/class/leds/<led>/blink_delay_on
+Date:		August 2025
+Contact:	Radoslav Tsvetkov <rtsvetkov@gradotech.eu>
+Description:	(RW) The time in milliseconds that the LED should be on while
+        blinking. Setting both blink_delay_on and blink_delay_off to
+        zero disables blinking.
+
+        Valid values: 0 to ULONG_MAX
+        Default: 0
+
+What:		/sys/class/leds/<led>/blink_delay_off
+Date:		August 2025

+Description:	(RW) The time in milliseconds that the LED should be off while
+        blinking. Setting both blink_delay_on and blink_delay_off to

+
+What:		/sys/class/leds/<led>/brightness
+Date:		August 2025
+Contact:	Radoslav Tsvetkov <rtsvetkov@gradotech.eu>
+Description:	(RW) Brightness value for the virtual LED group. This value is
+        applied to all monochromatic LEDs in the group if this group
+        has the highest priority among active groups.
+
+        When read-only mode is enabled via device tree, writes to this
+        attribute will return -EPERM.
+
+        Valid values: 0 to LED_FULL (usually 255)
+        Default: LED_OFF (0)
