1 * Qualcomm MSM UART 2 3 Required properties: 4 - compatible : 5 - "qcom,msm-uart", and one of "qcom,msm-hsuart" or 6 "qcom,msm-lsuart". 7 - reg : offset and length of the register set for the device 8 for the hsuart operating in compatible mode, there should be a 9 second pair describing the gsbi registers. 10 - interrupts : should contain the uart interrupt. 11 12 There are two different UART blocks used in MSM devices, 13 "qcom,msm-hsuart" and "qcom,msm-lsuart". The msm-serial driver is 14 able to handle both of these, and matches against the "qcom,msm-uart" 15 as the compatibility. 16 17 The registers for the "qcom,msm-hsuart" device need to specify both 18 register blocks, even for the common driver. 19 20 Example: 21 22 uart@19c400000 { 23 compatible = "qcom,msm-hsuart", "qcom,msm-uart"; 24 reg = <0x19c40000 0x1000>, 25 <0x19c00000 0x1000>; 26 interrupts = <195>; 27 };
