Subject: [PATCH v2 1/7] ASoC: fsl_sai: Add registers definition for multiple datalines
SAI IP supports up to 8 data lines. The configuration of
supported number of data lines is decided at SoC integration
time.
This patch adds definitions for all related data TX/RX registers:
* TDR0..7, Transmit data register
* TFR0..7, Transmit FIFO register
* RDR0..7, Receive data register
* RFR0..7, Receive FIFO register
Signed-off-by: Daniel Baluta <daniel.baluta@....com>
