From a software perspective it's mostly compatible 16cb7aa33aSEmmanuel Vadot with the MSM serial UARTDM except that it only supports reading and writing 17cb7aa33aSEmmanuel Vadot one character at a time. 18cb7aa33aSEmmanuel Vadot 19cb7aa33aSEmmanuel Vadotproperties: 20cb7aa33aSEmmanuel Vadot compatible: 21cb7aa33aSEmmanuel Vadot const: qcom,msm-uart 22cb7aa33aSEmmanuel Vadot 23cb7aa33aSEmmanuel Vadot clocks: 24cb7aa33aSEmmanuel Vadot maxItems: 1 25cb7aa33aSEmmanuel Vadot 26cb7aa33aSEmmanuel Vadot clock-names: 27cb7aa33aSEmmanuel Vadot items: 28cb7aa33aSEmmanuel Vadot - const: core 29cb7aa33aSEmmanuel Vadot 30cb7aa33aSEmmanuel Vadot interrupts: 31cb7aa33aSEmmanuel Vadot maxItems: 1 32cb7aa33aSEmmanuel Vadot 33cb7aa33aSEmmanuel Vadot reg: 34cb7aa33aSEmmanuel Vadot maxItems: 1 35cb7aa33aSEmmanuel Vadot 36cb7aa33aSEmmanuel Vadotrequired: 37cb7aa33aSEmmanuel Vadot - compatible 38cb7aa33aSEmmanuel Vadot - clock-names 39cb7aa33aSEmmanuel Vadot - clocks 40cb7aa33aSEmmanuel Vadot - interrupts 41cb7aa33aSEmmanuel Vadot - reg 42cb7aa33aSEmmanuel Vadot 43cb7aa33aSEmmanuel VadotallOf: 44cb7aa33aSEmmanuel Vadot - $ref: /schemas/serial/serial.yaml# 45cb7aa33aSEmmanuel Vadot 46*84943d6fSEmmanuel VadotunevaluatedProperties: false 47*84943d6fSEmmanuel Vadot 48cb7aa33aSEmmanuel Vadotexamples: 49cb7aa33aSEmmanuel Vadot - | 50cb7aa33aSEmmanuel Vadot serial@a9c00000 { 51cb7aa33aSEmmanuel Vadot compatible = "qcom,msm-uart"; 52cb7aa33aSEmmanuel Vadot reg = <0xa9c00000 0x1000>; 53cb7aa33aSEmmanuel Vadot interrupts = <11>; 54cb7aa33aSEmmanuel Vadot clocks = <&uart_cxc>; 55cb7aa33aSEmmanuel Vadot clock-names = "core"; 56cb7aa33aSEmmanuel Vadot }; 57
