-* STMicroelectronics SAS. ST NCI NFC Controller
-
-Required properties:
-- compatible: Should be "st,st21nfcb-i2c" or "st,st21nfcc-i2c".
-- clock-frequency: I²C work frequency.
-- reg: address on the bus
-- interrupt-parent: phandle for the interrupt gpio controller
-- interrupts: GPIO interrupt to which the chip is connected
-- reset-gpios: Output GPIO pin used to reset the ST21NFCB
-
-Optional SoC Specific Properties:
-- pinctrl-names: Contains only one value - "default".
-- pintctrl-0: Specifies the pin control groups used for this controller.
-
-Example (for ARM-based BeagleBoard xM with ST21NFCB on I2C2):
-
-&i2c2 {
-
- status = "okay";
-
- st21nfcb: st21nfcb@8 {
-
- compatible = "st,st21nfcb-i2c";
-
- reg = <0x08>;
- clock-frequency = <400000>;
-
- interrupt-parent = <&gpio5>;
- interrupts = <2 IRQ_TYPE_LEVEL_HIGH>;
-
- reset-gpios = <&gpio5 29 GPIO_ACTIVE_HIGH>;
- };
-};
