Qualcomm Technologies, Inc NQxxxx NFC NCI device
|
|
|
|
Near Field Communication (NFC) device is based on NFC Controller Interface (NCI)
|
|
|
|
Required properties:
|
|
|
|
- compatible: "qcom,nq-nci"
|
|
- reg: NCI i2c slave address.
|
|
- qcom,nq-ven: specific gpio for hardware reset.
|
|
- qcom,nq-irq: specific gpio for read interrupt.
|
|
- interrupt-parent: Should be phandle for the interrupt controller
|
|
that services interrupts for this device.
|
|
- interrupts: Nfc read interrupt,gpio-clk-req interrupt
|
|
|
|
|
|
Recommended properties:
|
|
|
|
- interrupt-names: names of interrupts, should include "nfc_irq", used for reference
|
|
|
|
|
|
Optional properties:
|
|
|
|
- pinctrl-names, pinctrl-0, pincntrl-1: references to our pincntrl settings
|
|
- clocks, clock-names: must contain the NQxxxx's core clock.
|
|
|
|
Example:
|
|
|
|
nq-nci@2b {
|
|
compatible = "qcom,nq-nci";
|
|
reg = <0x2b>;
|
|
qcom,irq-gpio = <&msm_gpio 29 0x00>;
|
|
qcom,en-gpio = <&msm_gpio 30 0x00>;
|
|
qcom,clk-src = "BBCLK2";
|
|
interrupt-parent = <&msm_gpio>;
|
|
interrupts = <29 0>;
|
|
interrupt-names = "nfc_irq";
|
|
pinctrl-names = "nfc_active","nfc_suspend";
|
|
pinctrl-0 = <&nfc_int_active &nfc_disable_active>;
|
|
pinctrl-1 = <&nfc_int_suspend &nfc_disable_suspend>;
|
|
qcom,clk-gpio = <&pm8916_gpios 2 0>;
|
|
clocks = <&clock_rpm clk_bb_clk2_pin>;
|
|
clock-names = "ref_clk";
|
|
};
