This is how OEM is using leds for LAN + WLAN.

ledc@191E000 {
			compatible = "qca,ledc";
			reg = <0x191e000 0x20070>;
			reg-names = "ledc_base_addr";
			qcom,tcsr_ledc_values = <0x320193 0x00 0x00 0x00 0x00 0xffffffff 0xffffffff 0xffffffff 0x7d0820 0x00 0x10482094 0x3ffffe1>;
			qcom,ledc_blink_indices_cnt = <0x06>;
			qcom,ledc_blink_indices = <0x0f 0x0e 0x0d 0x0c 0x0b 0x0a 0x17>;
			qcom,ledc_blink_idx_src_pair = <0x06 0x14>;
			status = "ok";
			pinctrl-0 = <0x2f>;
			pinctrl-names = "default";

			led_lan_g {
				label = "led_lan_g";
				linux,default-trigger = "none";
			};

			led_lan_o {
				label = "led_lan_o";
				linux,default-trigger = "none";
			};

			led_2g_b {
				label = "led_2g_b";
				linux,default-trigger = "none";
			};

			led_2g_g {
				label = "led_2g_g";
				linux,default-trigger = "none";
			};

			led_5g_b {
				label = "led_5g_b";
				linux,default-trigger = "none";
			};

			led_5g_g {
				label = "led_5g_g";
				linux,default-trigger = "none";
			};
		};

And in a script they do this

usage()
{
    echo -n "Usage : /etc/netgear_leds.sh <all|colour|led> <on|off>

    Valid arguments are :
    2g_blue         - Turn on/off 2.4G WLAN Blue colour LED
    2g_green        - Turn on/off 2.4G WLAN Green colour LED"
    if [ ${WLAN_NUM_RADIOS} = "3" ]; then
    echo -n "
    5g_low_blue     - Turn on/off 5G_LOW WLAN Blue colour LED
    5g_low_green    - Turn on/off 5G_LOW WLAN Green colour LED
    5g_high_blue    - Turn on/off 5G_HIGH WLAN Blue colour LED
    5g_high_green   - Turn on/off 5G_HIGH WLAN Green colour LED"
    else echo -n "
    5g_blue         - Turn on/off 5G WLAN Blue colour LED
    5g_green        - Turn on/off 5G WLAN Green colour LED"
    fi
    echo "
    pwr_green       - Turn on/off Power Green LED
    pwr_red         - Turn on/off Power Red LED
    pwr_blue        - Turn on/off Power Blue LED"
    if [ ${ETH_NUM_PORTS} = "2" ]; then
    echo -n "
    lan1_green      - Turn on/off LAN1 Green LED
    lan1_amber      - Turn on/off LAN1 Orange LED
    lan2_green      - Turn on/off LAN2 Green LED
    lan2_amber      - Turn on/off LAN2 Orange LED"
    else echo -n "
    lan_green       - Turn on/off LAN Green LED
    lan_amber       - Turn on/off LAN Orange LED"
    fi
    echo "
    blue            - Turn on/off all Blue LEDs
    green           - Turn on/off all Green LEDs
    red             - Turn on/off all Red LEDs
    amber           - Turn on/off all Amber LEDs     
    all             - Turn on/off all LEDs

    Example:
    /etc/netgear_leds.sh pwr_red off
    /etc/netgear_leds.sh all on"

	exit 1
}

And some of this

RESET_DELAY_ON=75
RESET_DELAY_OFF=75
DELAY_ON=1000
DELAY_OFF=1000

led_set_attr() {
        [ -f "/sys/class/leds/$1/$2" ] && echo "$3" > "/sys/class/leds/$1/$2"
}

led_timer() {
        led_set_attr $1 "trigger" "timer"
        led_set_attr $1 "delay_on" "$2"
        led_set_attr $1 "delay_off" "$3"
}

led_on() {
        led_set_attr $1 "trigger" "none"
        led_set_attr $1 "brightness" 255
}

led_off() {
        led_set_attr $1 "trigger" "none"
        led_set_attr $1 "brightness" 0
}

start_pwr_led_blink_green()
{
        led_timer led_pwr_g $DELAY_ON $DELAY_OFF
}

stop_pwr_led_blink_green()
{
        led_off led_pwr_g
}

Is this a smiliar way(ish) to how Verizon CR1000A is doing it?
