<div>Hi,</div>
<div> </div>
<div>Thanks a lot and sorry for the mistakes. I have gone through the trm of the adc as well as the omap driver. my question is that i want to interact the adc to the board. now should i directly use the omap driver or should i mak one of my own. if i make one of my own then i would like to know how would the spi registers be changed by driver. should it include the omap2 driver or is the fuctionality provided directly when i include spi.h.</div>
<div> </div>
<div>another doubt: when and why is the spidev.c/h used?</div>
<div> </div>
<div>i am deeply grateful towards you for helping me out</div>
<div>thanks</div>
