Subject: [PATCH 6/7] ASoC: dt-bindings: fsl-sai: Add new property to configure dataline
"fsl,dataline" is added to configure the dataline of SAI.
It has 3 value for each configuration, first one means the type:
I2S(1) or PDM(2), second one is dataline mask for 'rx', third one is
dataline mask for 'tx'. for example:
fsl,dataline = <1 0xff 0xff 2 0xff 0x11>,
it means I2S type rx mask is 0xff, tx mask is 0xff, PDM type
rx mask is 0xff, tx mask is 0x11 (dataline 1 and 4 enabled).
