Add driver model support so that ns16550 can support operation both with and without driver model. The driver needs a clock frequency so cannot stand alone unfortunately. The clock frequency must be provided by a separate driver. Signed-off-by: Simon Glass <sjg@chromium.org>

NS16550 UART
|
|
|
|
This UART driver supports many chip variants and is used in mamy SoCs.
|
|
|
|
Required properties:
|
|
- compatible: "ns16550" or "nvidia,tegra20-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)
