Modify the probe routine to get the port line number from device tree if the 'of_node' is populated in the platform device. The driver can be built as module, thus add an OF specific module device table as well to support module auto loading. This makes it possible to use the driver for AR9330 UART devices specified in device tree.

* Qualcomm Atheros AR9330 High-Speed UART
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must be "qca,ar9330-uart"
|
|
|
|
- reg: Specifies the physical base address of the controller and
|
|
the length of the memory mapped region.
|
|
|
|
- interrupt-parent: The phandle for the interrupt controller that
|
|
services interrupts for this device.
|
|
|
|
- interrupts: Specifies the interrupt source of the parent interrupt
|
|
controller. The format of the interrupt specifier depends on the
|
|
parent interrupt controller.
|
|
|
|
Additional requirements:
|
|
|
|
Each UART port must have an alias correctly numbered in "aliases"
|
|
node.
|
|
|
|
Example:
|
|
|
|
aliases {
|
|
serial0 = &uart0;
|
|
};
|
|
|
|
uart0: uart@18020000 {
|
|
compatible = "qca,ar9330-uart";
|
|
reg = <0x18020000 0x14>;
|
|
|
|
interrupt-parent = <&intc>;
|
|
interrupts = <3>;
|
|
};
