The device I use has the QCA4024 chip connected via the spi controller:
blsp1_spi4: spi@78b8000 {
compatible = "qcom,spi-qup-v2.2.1";
#address-cells = <1>;
#size-cells = <0>;
reg = <0x78b8000 0x600>;
interrupts = <GIC_SPI 98 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&gcc GCC_BLSP1_QUP4_SPI_APPS_CLK>,
<&gcc GCC_BLSP1_AHB_CLK>;
clock-names = "core", "iface";
dmas = <&blsp_dma 18>, <&blsp_dma 19>;
dma-names = "tx", "rx";
status = "disabled";
};
and apart from setting the frequency and gpio there is nothing else:
&blsp1_spi4 {
status = "okay";
pinctrl-0 = <&spi_3_pins &quartz_pins>;
pinctrl-names = "default";
/* Qualcomm QCA4024 IoT */
iot@3 {
compatible = "qca,qca4024";
reg = <0>;
spi-max-frequency = <24000000>;
};
};
&tlmm {
spi_3_pins: spi-3-state {
spi-pins {
pins = "gpio50", "gpio52", "gpio53";
function = "blsp3_spi";
drive-strength = <8>;
bias-disable;
};
cs-pins {
pins = "gpio22";
function = "blsp3_spi2";
drive-strength = <8>;
bias-disable;
};
};
quartz_pins: quartz-state {
interrupt-pins {
pins = "gpio48";
function = "gpio";
bias-disable;
input;
};
reset-pins {
pins = "gpio21";
function = "gpio";
bias-disable;
output-high;
};
};
};
