tty: ar933x_uart: move devicetree binding documentation
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>;
+ };
