Thanks Paul for looping me in, something went wrong with my l-o subscription, 
so I didn't receive these Patches. 

As far as lck clock node is concerned, we had deliberately dropped all leaf-
node clocks from the clock tree, please refer to the description mentioned 
in -
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-May/101987.html


>From LCDC driver perspective, driver is using,

fb_clk = clk_get(&device->dev, NULL);

This I feel needs to be corrected for valid name as per Spec (mostly I would 
vote for "fck") and then every platform should make sure that it returns 
valid clock-node for it.

Change in Driver would be,

fb_clk = clk_get(&device->dev, "fck");


Thanks,
Vaibhav
