Not sure why you were down voted. The test only showed removing the chip disabled the camera. The chip BCM15700A2 is a WLAN/Bluetooth chip used on Intel 8260 cards and lots of Dell laptops.

There is a Linux kernel driver written for this chip used for 802.11a wireless.

The 15700 is a PCIe bridge and PLX chip with some signal conversion capabilities it was never even designated as a wireless chip heck we have apple’s manuals:

338S1186 1 IC,BCM15700A2,S2 PCIE CAMERA PROCESSOR U3900 CRITICAL

5 digit part numbers are Broadcom’s “IP bridge SoC” the BCM15900 on the iPAD pro for example handles the eDP connection with the screen IIRC and the digitizer function.

Got a source for that? I can't find any references to the 15700A2 being on intel 8260 cards.
