Hello,
I have a custom board based on TI's AM5728 EVM. I am using the latest Linux PSDK 6.03 on it.
I am using Spark LAN WNFQ-258ACN(BT), which is an 802.11ac/a/b/g/n Dual-Band Wi-Fi+Bluetooth M.2 card based on Qualcomm Atheros QCA6174A chipset. The interface for WiFi is PCIe and for Bluetooth is USB.
I have connected the WiFi device to PCIe_SS1 (PCIe0) in single-lane host mode. The PCIe is configured as RC (root complex) in the board-level device tree file.
Following are the device tree entries -
pcie1_rc: pcie@51000000 {
reg = <0x51000000 0x2000>, <0x51002000 0x14c>, <0x1000 0x2000>;
reg-names = "rc_dbics", "ti_conf", "config";
interrupts = <0 232 0x4>, <0 233 0x4>;
#address-cells = <3>;
#size-cells = <2>;
device_type = "pci";
ranges = <0x81000000 0 0 0x03000 0 0x00010000
0x82000000 0 0x20013000 0x13000 0 0xffed000>;
bus-range = <0x00 0xff>;
#interrupt-cells = <1>;
num-lanes = <1>;
linux,pci-domain = <0>;
ti,hwmods = "pcie1";
phys = <&pcie1_phy>;
phy-names = "pcie-phy0";
ti,syscon-lane-sel = <&scm_conf_pcie 0x18>;
interrupt-map-mask = <0 0 0 7>;
interrupt-map = <0 0 0 1 &pcie1_intc 1>,
<0 0 0 2 &pcie1_intc 2>,
<0 0 0 3 &pcie1_intc 3>,
<0 0 0 4 &pcie1_intc 4>;
ti,syscon-unaligned-access = <&scm_conf1 0x14 1>;
status = "disabled";
pcie1_intc: interrupt-controller {
interrupt-controller;
#address-cells = <0>;
#interrupt-cells = <1>;
};
};
&pcie1_rc {
status = "okay";
gpios = <&gpio2 8 GPIO_ACTIVE_LOW>;
};
I am getting the following logs in the kernel while booting -

But the WiFi device is not detected in lspci output. However, the Bluetooth device is detected in lsusb output.
root@am57xx-evm:~# lspci 00:00.0 PCI bridge: Texas Instruments Multicore DSP+ARM KeyStone II SOC (rev 01) root@am57xx-evm:~# lsusb Bus 001 Device 003: ID 0cf3:e300 Qualcomm Atheros Communications Bus 001 Device 002: ID 0451:8142 Texas Instruments, Inc.

Also, after inserting the WiFi driver (Atheros 10k based), lspci gives the same output. The wlanX interface is also not getting created.
I am not able to understand why the device is not detected. Am I missing something else here?
Kindly acknowledge and revert.
