Hi Clayton,

Thanks for the patch -- it looks good to me aside from one minor comment 
below.

Will other modes be added to this struct in the future? If so, I think 
we can probably turn this into an array to make it easier to extend.

Otherwise, can you change the name to "*_mode"? Seems to me that almost 
all other panels with a single mode have the name as "*_mode" with the 
only exception being a carry-over from older panel-simple.c code.

Thanks,

Jessica Zhang

To be honest, I have no idea. I saw a kernel backtrace in dmesg that was related
to this driver not having config for my panel, so I added it after looking at
similar examples here.

Personally I'd prefer not to get too fancy with arrays and such until there's
actually a need for it, e.g., someone comes along with more modes to add. But I
can try to do that if my "keep it simple until it needs to be extended" approach
is unacceptable :)

Ok I'll rename to *_mode in V2. Thanks for reviewing!
