Almost all files in the kernel are either plain text or UTF-8 encoded. A couple however are ISO_8859-1, usually just a few characters in a C comments, for historic reasons. This converts them all to UTF-8 for consistency.

* NXP Semiconductors PN544 NFC Controller
|
|
|
|
Required properties:
|
|
- compatible: Should be "nxp,pn544-i2c".
|
|
- clock-frequency: I²C work frequency.
|
|
- reg: address on the bus
|
|
- interrupts: GPIO interrupt to which the chip is connected
|
|
- enable-gpios: Output GPIO pin used for enabling/disabling the PN544
|
|
- firmware-gpios: Output GPIO pin used to enter firmware download mode
|
|
|
|
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 BeagleBone with PN544 on I2C2):
|
|
|
|
&i2c2 {
|
|
|
|
|
|
pn544: pn544@28 {
|
|
|
|
compatible = "nxp,pn544-i2c";
|
|
|
|
reg = <0x28>;
|
|
clock-frequency = <400000>;
|
|
|
|
interrupt-parent = <&gpio1>;
|
|
interrupts = <17 GPIO_ACTIVE_HIGH>;
|
|
|
|
enable-gpios = <&gpio3 21 GPIO_ACTIVE_HIGH>;
|
|
firmware-gpios = <&gpio3 19 GPIO_ACTIVE_HIGH>;
|
|
};
|
|
};
