Hello Vijay,<br>
<br>
it's great that you now have a working driver. Well done.<br>
<br>
I hadn't had a look at most patches yet and most likely that will need a<br>
bit of time. It's a lot of stuff. Most likely the bigger patches won't<br>
reach the mailing list so maybe adding a link to a branch on your github<br>
repo would be good.<br>

Note: Please don't send a v2 right now. I'm sure there are more comments<br>
(maybe not only from me). Collect comments for at least one or two days<br>
and create an update afterwards.<br>

Some notes reading the patch overview:<br>

<br>
Is fbd a prerequisite of am335x_lcd? In that case it would have been<br>
better to reorder the patches. As long as every version compiles (to<br>
allow git bisect) I would accept that order too. But as a general rule<br>
prerequisites should be prior to the parts that use it.<br>
<br></blockquote><div>am335x_lcd is the prerequisite for fbd. </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<br>
Is the vt still necessary? I think it was an intermediate step to try<br>
whether it's initializing the display. Did you try without it?<br>
<br></blockquote><div>I tried without it, it's giving some noise in the screen and the the open</div><div>call to framebuffer is returning error without vt. I guess the vt initialization</div><div>is necessary. </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Again: prerequisite. So they should be one of the first.<br>
<br></blockquote><div>OK. I'll put it in the first. </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
