-* Cirrus Logic CLPS711X Universal Asynchronous Receiver/Transmitter (UART)
-
-Required properties:
-- compatible: Should be "cirrus,ep7209-uart".
-- reg: Address and length of the register set for the device.
-- interrupts: Should contain UART TX and RX interrupt.
-- clocks: Should contain UART core clock number.
-- syscon: Phandle to SYSCON node, which contain UART control bits.
-
-Optional properties:
-- {rts,cts,dtr,dsr,rng,dcd}-gpios: specify a GPIO for RTS/CTS/DTR/DSR/RI/DCD
- line respectively.
-
-Note: Each UART port should have an alias correctly numbered
-in "aliases" node.
-
-Example:
- aliases {
- serial0 = &uart1;
- };
-
- uart1: uart@80000480 {
- compatible = "cirrus,ep7312-uart","cirrus,ep7209-uart";
- reg = <0x80000480 0x80>;
- interrupts = <12 13>;
- clocks = <&clks 11>;
- syscon = <&syscon1>;
- cts-gpios = <&sysgpio 0 GPIO_ACTIVE_LOW>;
- dsr-gpios = <&sysgpio 1 GPIO_ACTIVE_LOW>;
- dcd-gpios = <&sysgpio 2 GPIO_ACTIVE_LOW>;
- };

Convert the Cirrus EP7209 UART binding to DT schema. There is no user of "cirrus,ep7312-uart" other than the example, so drop it. Drop the "aliases" node part as it is not relevant to the schema. The modem control GPIOs are covered by the serial.yaml schema and don't have to be listed in the schema.
