I think TDM slot number is possible but not TX/RX mask. What we have in topology
is union of tx/rx mask of all channels. We don't know the mask of specific channel in
DAI_CONFIG.

DAI_CONFIG(SSP, 0, BOARD_HP_BE_ID, SSP0-Codec,
        SSP_CONFIG(I2S, SSP_CLOCK(mclk, 19200000, codec_mclk_in),
                SSP_CLOCK(bclk, 2400000, codec_slave),
                SSP_CLOCK(fsync, 48000, codec_slave),
                SSP_TDM(2, 25, 3, 3),
                SSP_CONFIG_DATA(SSP, 0, 24, 0, 0, 0, SSP_CC_BCLK_ES)))')

Brent
