LS1046的dts关于uart的配置如下:
serial@21c0500 {
compatible = "fsl,ns16550", "ns16550a";
reg = <0x0 0x21c0500 0x0 0x100>;
interrupts = <0x0 0x36 0x4>;
clocks = <0x2 0x4 0x1>;
status = "okay";
};
serial@21c0600 {
compatible = "fsl,ns16550", "ns16550a";
reg = <0x0 0x21c0600 0x0 0x100>;
interrupts = <0x0 0x36 0x4>;
clocks = <0x2 0x4 0x1>;
status = "okay";
};
serial@21d0500 {
compatible = "fsl,ns16550", "ns16550a";
reg = <0x0 0x21d0500 0x0 0x100>;
interrupts = <0x0 0x37 0x4>;
clocks = <0x2 0x4 0x1>;
status = "okay";
};
serial@21d0600 {
compatible = "fsl,ns16550", "ns16550a";
reg = <0x0 0x21d0600 0x0 0x100>;
interrupts = <0x0 0x37 0x4>;
clocks = <0x2 0x4 0x1>;
status = "okay";
};
现在需要把如下的4个GPIO模式调成GPIO模式,不在用作UART的tx rx。这个在Ubunt系统和Vxworks下面哪里修改这个默认的模式?
