Commit 'tty: ar933x_uart: add device tree support and binding documentation' introduced a new doc in bindins/tty/serial. According to a recent thread [1] on the linux-serial list, the binding documentation of serial drivers should be added into bindings/serial. Move the documentation of qca,ar9330-uart to the correct place. 1. http://marc.info/?l=linux-serial&m=137771295411517 Cc: devicetree@vger.kernel.org Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* 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>;
|
|
};
