1*c66ec88fSEmmanuel Vadot* MSM Serial UART 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotThe MSM serial UART hardware is designed for low-speed use cases where a 4*c66ec88fSEmmanuel Vadotdma-engine isn't needed. From a software perspective it's mostly compatible 5*c66ec88fSEmmanuel Vadotwith the MSM serial UARTDM except that it only supports reading and writing one 6*c66ec88fSEmmanuel Vadotcharacter at a time. 7*c66ec88fSEmmanuel Vadot 8*c66ec88fSEmmanuel VadotRequired properties: 9*c66ec88fSEmmanuel Vadot- compatible: Should contain "qcom,msm-uart" 10*c66ec88fSEmmanuel Vadot- reg: Should contain UART register location and length. 11*c66ec88fSEmmanuel Vadot- interrupts: Should contain UART interrupt. 12*c66ec88fSEmmanuel Vadot- clocks: Should contain the core clock. 13*c66ec88fSEmmanuel Vadot- clock-names: Should be "core". 14*c66ec88fSEmmanuel Vadot 15*c66ec88fSEmmanuel VadotExample: 16*c66ec88fSEmmanuel Vadot 17*c66ec88fSEmmanuel VadotA uart device at 0xa9c00000 with interrupt 11. 18*c66ec88fSEmmanuel Vadot 19*c66ec88fSEmmanuel Vadotserial@a9c00000 { 20*c66ec88fSEmmanuel Vadot compatible = "qcom,msm-uart"; 21*c66ec88fSEmmanuel Vadot reg = <0xa9c00000 0x1000>; 22*c66ec88fSEmmanuel Vadot interrupts = <11>; 23*c66ec88fSEmmanuel Vadot clocks = <&uart_cxc>; 24*c66ec88fSEmmanuel Vadot clock-names = "core"; 25*c66ec88fSEmmanuel Vadot}; 26
