Hi Eric,

You're right. I think LCDCLK is only ever requested by pxa_device_fb.

I see now that instead of doing:
-       fbi->clk = clk_get(dev, "LCDCLK");
+       fbi->clk = clk_get(inf->clkdev, "LCDCLK");

a better solution would be to directly use pxa_device_fb:
-       fbi->clk = clk_get(dev, "LCDCLK");
+       fbi->clk = clk_get(pxa_device_fb.dev, "LCDCLK");

and then I can avoid doing the clkdev ugliness.

Thanks,
jaya
