Some files over there won't parse well by Sphinx.

Fix them.

What: /sys/bus/iio/devices/iio:deviceX/in_voltage_spi_clk_freq KernelVersion: 4.14 Contact: arnaud.pouliquen@st.com Description: For audio purpose only.

	Used by audio driver to set/get the spi input frequency.

	This is mandatory if DFSDM is slave on SPI bus, to
	provide information on the SPI clock frequency during runtime
	Notice that the SPI frequency should be a multiple of sample
	frequency to ensure the precision.

	if DFSDM input is SPI master:

		Reading  SPI clkout frequency,
		error on writing

	If DFSDM input is SPI Slave:

		Reading returns value previously set.
		Writing value before starting conversions.
