Required properties:
- compatible: Should be "st,st21nfcb-spi"
-- spi-max-frequency: Maximum SPI frequency (<= 10000000).
+- spi-max-frequency: Maximum SPI frequency (<= 4000000).
- 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.
+- ese-present: Specifies that an ese is physically connected to the nfc
+controller.
+- uicc-present: Specifies that the uicc swp signal can be physically
+connected to the nfc controller.
Example (for ARM-based BeagleBoard xM with ST21NFCB on SPI4):
interrupts = <2 IRQ_TYPE_EDGE_RISING>;
reset-gpios = <&gpio5 29 GPIO_ACTIVE_HIGH>;

+ ese-present;
+ uicc-present;
