Hi Linus, Yes, we don't need to call prepare() again atleast for SPEAr. You are correct. I saw the driver after a long time :) Can you please elaborate, why can't i see any clk_disable/enable calls anywhere else from probe. If i remember correctly, earlier we used to enable/disable clk after transfers and also during suspend/resume. The amba layer is taking care of interface clock only and not functional clock. So i believe that's not the magic code. :) -- viresh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
