The Sony/Philips Digital Interface Receiver (SPDIFRX) is a serial port
compliant with the IEC-60958 standard. Among its caracteristics, we
mention the following:
 - SPDIF/AES-EBU Compatible Serial Port
 - 32 Samples FIFO
 - Data Width Configurable to 24 bits, 20 bits or 16 bits
 - Packed and Unpacked Data Support for System Memory Optimization
 - Line State Events Report and Source of Interrupt
 - Line Error Rate Report
 - Full Memory Map of 192 bits for Channel 1 and Channel 2 Status and
   User Data
 - First 32-bit Status A, Status B Change Report and Source of Interrupt
 - Line Digital Filter
 - Register Write Protection
 - Abnormal Software Access and Internal Sequencer Integrity Check Reports

This interface is available in Microchip's SAMA7G5 SoC.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
