| 3 | This UART driver supports many chip variants and is used in mamy SoCs. | ||||
| 4 | |||||
| 5 | Required properties: | ||||
| 6 | - compatible: "ns16550" or "nvidia,tegra20-uart" | ||||
| 7 | - reg: start address and size of registers | ||||
| 8 | - reg-shift: shift value indicating register size: 0=byte, 1=16bit,2=32bit etc. | ||||
| 9 | - clock-frequency: input clock frequency for the UART (used to calculate the | ||||
| 10 | baud rate divisor) | ||||
