SPI protocol driver for Qualcomm Atheros QCA7000 serial-to-powerline bridge chip
This driver has been merged in the mainline kernel since Linux 3.18 ( http://lxr.free-electrons.com/source/drivers/net/ethernet/qualcomm/ ).

If you want to use the QCA7000 in combination with a Raspberry Pi and the Foundation Kernel feel free to use this overlay: https://github.com/raspberrypi/linux/blob/rpi-4.1.y/arch/arm/boot/dts/overlays/qca7000-overlay.dts
