I2S configurations are not reflecting in kernel

Hi,
I am working on custom-board imx6q sabre and at one point i am not getting understand is that i have make changes in dtsi file where i have write I2S as Master in SSI and bitbake my custom configuration settings and i can read the dtb file by using fdtdump command and i see the change in the file as per the changes i made but when i tried to see the changes of SSI by using memtool (e.g memtool -32 0x02028010 ), it is showing the value=000000000, i am not able to see the changes as per my configuration i should get 00000020(SSI I2S Master-mode e.g. register SSI_SCR[6:5] = 01)
Please let me know if i have do some more changes.

Hi Rohit

ASoC splits an embedded audio system into several components described in

Figure 28-1. ALSA SoC Software Architecture attached Linux Manual.

So it is necessary that all drivers (machine, platform, codec) were loaded correctly.

Please check them in sect.28.4.1 ASoC Driver Source Architecture

Best regards
igor
