<div>Hi,</div>
<div> </div>
<div>I also didnt get any good doc on the mmc sub system </div>
<div>whereas there are few things that might help</div>
<div>A slide which explains driver stack:- </div>
<div><a href="http://www.slideshare.net/champ_yen/linux-sdmmc-driver-stack">http://www.slideshare.net/champ_yen/linux-sdmmc-driver-stack</a></div>
<div>
<div>
<div>
<div> </div>
<div>Check JEDEC specs (open standard for MMC /eMMC)</div>
<div><a href="http://www.jedec.org/sites/default/files/docs/JESD84-A441.pdf">http://www.jedec.org/sites/default/files/docs/JESD84-A441.pdf</a> </div></div> </div></div>
<div>1. Card</div>
<div>you can look into linux kernel directory drivers/mmc/card/ </div>
<div>very few files and easy to understand. can map with JEDEC pdf.</div>
<div>Block.c , queue.c and mmc_test.c</div>
<div>
<div> </div></div>
<div>2. Core </div>
<div>Generic layer - Not much to be done in this if you are writing a driver or so.</div>
<div> </div>
<div>3. Host </div>
<div>drivers/mmc/host/</div>
<div>There are few sample mmc driver file are there although </div>
<div>This is specific to your chip. so needed data sheet. Also JEDEC spec can help a bit.</div>
<div><br>Hope this helps.</div>
<div>Thanks </div>
<div>Manish <br> </div>
