Hello,

I am working on development of a teleconferencing product that incorporates the Laird Sterling-LWB WiFi/Bluetooth module based on the CYW4343W device.  This module is integrated into a Variscite iMX 8M Plus (imx8mp) System-on-Module.

In addition to WiFi and Bluetooth this product also features an LTE interface.  At this moment we are battling a system noise problem that is causing interference with one of the LTE bands and is preventing LTE certification to pass.  Specifically the noise peak is at 750 MHz and the LTE band that is failing is at 751 MHz.  I have found that the source of the generated noise is the WiFi module or signals attached or in close proximity with it; if I disable the brcmfmac driver, the noise peak disappears and the LTE performance is acceptable.

Here is the version of the brcmfmac driver that is currently being used:

09-16 15:14:28.946 0 0 I brcmfmac: brcmf_fw_alloc_request: using brcm/brcmfmac43430-sdio for chip BCM43430/1
09-16 15:14:28.958 0 0 I brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM43430/1 wl0: Feb 16 2020 22:39:24 version 7.45.98.97 (r724416 CY) FWID 01-bf41ed64

Here is what I would like to find out (either one would help):

(1) Is there a provision in the brcmfmac driver that can allow a user space application to disable the driver and re-enable it?  I have noticed in the device tree these signals that seem to indicate that software is able to control the power to the module and enable/disable it:

&usdhc1 {
  #address-cells = <1>;
  #size-cells = <0>;
  pinctrl-names = "default", "state_100mhz", "state_200mhz";
  pinctrl-0 = <&pinctrl_usdhc1>, <&pinctrl_wifi>;
  pinctrl-1 = <&pinctrl_usdhc1_100mhz>, <&pinctrl_wifi>;
  pinctrl-2 = <&pinctrl_usdhc1_200mhz>, <&pinctrl_wifi>;
  bus-width = <4>;
  non-removable;
  keep-power-in-suspend;
  status = "okay";

  brcmf: bcrmf@1 {
    reg = <1>;
    compatible = "brcm,bcm4329-fmac";
  };
};

pinctrl_wifi: wifigrp {
  fsl,pins = <
    MX8MP_IOMUXC_SD1_DATA5__GPIO2_IO07 0xc1 /* WIFI_EN */
    MX8MP_IOMUXC_SD1_DATA6__GPIO2_IO08 0xc1 /* WIFI_PWR */
  >;
};

However, I am not finding in the brcmfmac driver code how these signals are managed.

(2)  Is there a way to control the timing configuration in the module to possibly shift the 750 MHz component to a different frequency?  I am not sure what the source of this component is.  There is probably a clock operating at a rate that is a factor of this frequency, such as 50 MHz or 250 MHz.  I know from the data sheet that there is (should be) a clock operating at 37.4 MHz; but that would cause a peak at 748 MHz, not 750 MHz.

Thanks for any help you may be able to provide.
