In old place of power LED a GPIO controllable heartbeat LED +was added. This commit only touches Single Shot variant, since only this +variant is all revision 1.3. + +Note: +This is slightly modified patch. Some boards could be placed in an +enclosure, so the LED18 is enabled by default, since that'll be the only +visible indicator that the board is operating. + +Reported-by: Alexandra Alth <alexandra@alth.de> +Signed-off-by: Tomasz Maciej Nowak <tmn505@gmail.com> +Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com> +--- + .../marvell/armada-8040-mcbin-singleshot.dts | 22 +++++++++++++++++++ + 1 file changed, 22 insertions(+) + +--- a/arch/arm64/boot/dts/marvell/armada-8040-mcbin-singleshot.dts ++++ b/arch/arm64/boot/dts/marvell/armada-8040-mcbin-singleshot.dts +@@ -5,6 +5,8 @@ + * Device Tree file for MACCHIATOBin Armada 8040 community board platform + */ + ++#include <dt-bindings/leds/common.h> ++ + #include "armada-8040-mcbin.dtsi" + + / { +@@ -12,6 +14,20 @@ + compatible = "marvell,armada8040-mcbin-singleshot", + "marvell,armada8040-mcbin", "marvell,armada8040", + "marvell,armada-ap806-quad", "marvell,armada-ap806"; ++ ++ leds { ++ compatible = "gpio-leds"; ++ pinctrl-0 = <&cp0_led18_pins>; ++ pinctrl-names = "default"; ++ ++ led18 { ++ gpios = <&cp0_gpio2 1 GPIO_ACTIVE_LOW>; ++ function = LED_FUNCTION_HEARTBEAT; ++ color = <LED_COLOR_ID_GREEN>; ++ linux,default-trigger = "heartbeat"; ++ default-state = "on"; ++ }; ++ }; + }; + + &cp0_eth0 { +@@ -27,3 +43,10 @@ + managed = "in-band-status"; + sfp = <&sfp_eth1>; + }; ++ ++&cp0_pinctrl { ++ cp0_led18_pins: led18-pins { ++ marvell,pins = "mpp33"; ++ marvell,function = "gpio"; ++ }; ++}; |
