Since the GPIO driver does not provide that, revert the beeper support to a simple gpio-export. This effectively reverts the corresponding changes from 6ba58b7b020c ("ramips: cleanup the RB750Gr3 support") Signed-off-by: John Thomson [commit title/message facelift] Signed-off-by: Adrian Schmutzler --- diff --git a/target/linux/ramips/dts/mt7621_mikrotik_routerboard-750gr3.dts b/target/linux/ramips/dts/mt7621_mikrotik_routerboard-750gr3.dts index a516f337cc..f767599e98 100644 --- a/target/linux/ramips/dts/mt7621_mikrotik_routerboard-750gr3.dts +++ b/target/linux/ramips/dts/mt7621_mikrotik_routerboard-750gr3.dts @@ -52,15 +52,17 @@ }; }; - beeper { - compatible = "gpio-beeper"; - gpios = <&gpio 15 GPIO_ACTIVE_HIGH>; - }; - gpio_export { compatible = "gpio-export"; #size-cells = <0>; + buzzer { + /* Beeper requires PWM for frequency selection */ + gpio-export,name = "buzzer"; + gpio-export,output = <0>; + gpios = <&gpio 15 GPIO_ACTIVE_HIGH>; + }; + usb_power { gpio-export,name = "usb_power"; gpio-export,output = <1>; diff --git a/target/linux/ramips/image/mt7621.mk b/target/linux/ramips/image/mt7621.mk index c922303c54..16b74c7b3e 100644 --- a/target/linux/ramips/image/mt7621.mk +++ b/target/linux/ramips/image/mt7621.mk @@ -703,7 +703,7 @@ endef define Device/mikrotik_routerboard-750gr3 $(Device/MikroTik) DEVICE_MODEL := RouterBOARD 750Gr3 - DEVICE_PACKAGES += kmod-gpio-beeper -wpad-basic + DEVICE_PACKAGES += -wpad-basic SUPPORTED_DEVICES += mikrotik,rb750gr3 endef TARGET_DEVICES += mikrotik_routerboard-750gr3
