2020-07-28MLK-24413: ASoC: fsl_xcvr: fix SPDIF RX/TX sequence issueViorel Suman
In SPDIF full duplex mode in order to get both RX and TX working we need to start RX first, and TX second, fix this by porting SPDIF RX configuration code from XCVR FW into Kernel driver and avoid using M0+ core for SPDIF configuration.

2020-07-17MLK-24412: ASoC: fsl_xcvr: remove support for S24_LE TXViorel Suman
There is no need for S24_LE support on TX since IEC958 ALSA plugin is now configured to cover this function. Signed-off-by: Viorel Suman <viorel.suman@nxp.com> Reviewed-by: Shengjiu Wang <shengjiu.wang@nxp.com>
2020-06-11MLK-24276: ASoC: fsl_xcvr: fix SPDIF TX suspend/resumeViorel Suman
SPDIF TX fails to play after resume because PHY is put in reset on suspend, and is not re-initialized on resume. Move SPDIF TX configuration in "prepare" callback since "prepare" is called after resume. Signed-off-by: Viorel Suman <viorel.suman@nxp.com> Reviewed-by: Shengjiu Wang <shengjiu.wang@nxp.com>

At SPDIF TX interrupt the firmware running on M0+ core overwrites TX DPATH BYPASS FEM bit which turns the expected PHY DMAC TX PLL clock 2*bitclock instead of expected 10*bitclock if SAI PLL is used as PHY DMAC TX PLL.
