This UART driver supports many chip variants and is used in mamy SoCs.
Required properties:
-- compatible: "ns16550" or "nvidia,tegra20-uart"
+- compatible: one of:
+ - "ns16550"
+ - "ns16550a"
+ - "nvidia,tegra20-uart"
+ - "snps,dw-apb-uart"
+ - "ti,omap2-uart"
+ - "ti,omap3-uart"
+ - "ti,omap4-uart"
+ - "ti,am3352-uart"
+ - "ti,am4372-uart"
+ - "ti,dra742-uart"
- reg: start address and size of registers
-- reg-shift: shift value indicating register size: 0=byte, 1=16bit,2=32bit etc.
- clock-frequency: input clock frequency for the UART (used to calculate the
baud rate divisor)
+
+Optional properties:
+- reg-shift: shift value indicating register size: 0=byte, 1=16bit, 2=32bit
etc.
+ default to 0 if not given.
