| * Synopsys DesignWare ABP UART |
| |
| Required properties: |
| - compatible : "snps,dw-apb-uart" |
| - reg : offset and length of the register set for the device. |
| - interrupts : should contain uart interrupt. |
| - clock-frequency : the input clock frequency for the UART. |
| |
| Optional properties: |
| - reg-shift : quantity to shift the register offsets by. If this property is |
| not present then the register offsets are not shifted. |
| - reg-io-width : the size (in bytes) of the IO accesses that should be |
| performed on the device. If this property is not present then single byte |
| accesses are used. |
| |
| Example: |
| |
| uart@80230000 { |
| compatible = "snps,dw-apb-uart"; |
| reg = <0x80230000 0x100>; |
| clock-frequency = <3686400>; |
| interrupts = <10>; |
| reg-shift = <2>; |
| reg-io-width = <4>; |
| }; |
