Qualcomm Technologies, Inc. QBT1000 Specific Bindings
QBT is a fingerprint sensor ASIC capable of performing fingerprint image scans
and detecting finger presence on the sensor using programmable firmware.
=======================
Required Node Structure
=======================
- compatible
Usage: required
Value type: <string>
Definition: "qcom,qbt1000".
- clock-names
Usage: required
Value type: <stringlist>
Definition: List of clock names that need to be voted on/off.
- clocks
Usage: required
Value type: <prop_encoded-array>
Definition: Property pair that represents the clock controller and the clock
id. This in combination with the clock-name is used to obtain
the handle for the clock that needs to be voted on/off.
- clock-frequency
Usage: required
Value type: <u32>
Definition: Frequency of clock in Hz.
- qcom,ipc-gpio
Usage: required
Value type: <phandle>
Definition: phandle for GPIO to be used for IPC.
- qcom,finger-detect-gpio
Usage: required
Value type: <phandle>
Definition: phandle for GPIO to be used for finger detect.
=======
Example
=======
qcom,qbt1000 {
compatible = "qcom,qbt1000";
clock-names = "core", "iface";
clocks = <&clock_gcc clk_gcc_blsp2_qup6_spi_apps_clk>,
<&clock_gcc clk_gcc_blsp2_ahb_clk>;
clock-frequency = <15000000>;
qcom,ipc-gpio = <&tlmm 121 0>;
qcom,finger-detect-gpio = <&pm8998_gpios 2 0>;
};
