I am surfing in the device tree files for stm32f412 micro

I found

usart3: serial@40004800 {
   compatible = "st,stm32-usart", "st,stm32-uart";
   reg = <0x40004800 0x400>;
   clocks = <&rcc STM32_CLOCK_BUS_APB1 0x00040000>;
   interrupts = <39 0>;
   status = "disabled";
   label = "UART_3";
};

I wonder where to find documentation about clocks entry. It seems to be a 3 element array, but I don't know the meaning of each of them


best regards
