ASoC: atmel: mchp-pdmc: add PDMC driver

	  This S/PDIF RX driver is compliant with IEC-60958 standard and

	  includes programmable User Data and Channel Status fields.

	tristate "Microchip ASoC driver for boards using PDMC"

	depends on OF && (ARCH_AT91 || COMPILE_TEST)

	help

	  Say Y or M if you want to add support for Microchip ASoC PDMC driver on the

	  following Microchip platforms:

	  - sama7g5

	  The Pulse Density Microphone Controller (PDMC) interfaces up to 4 digital

	  microphones PDM outputs. It generates a single clock line and samples 1 or

	  2 data lines. The signal path includes an audio grade programmable

	  decimation filter and outputs 24-bit audio words.
