Christophe Ricard 1a94cb6025 NFC: dts: st21nfcb: Fix compatible string spelling to follow other drivers
Other drivers are following the following compatible string format for dts:
s/_/-/

Because some devices may still use the previous string, the new corrected
string is added to the of_device_id table.

* STMicroelectronics SAS. ST21NFCB NFC Controller
Required properties:
- compatible: Should be "st,st21nfcb-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>;
};
};
