Re: [PATCH 0/2] OMAP3 ISP: Simplify clock usage

This simplifies the ISP clocks configuration. I'm pleased to see this feature get used on OMAP. Plus your driver gets a negative diffstat :) Reviewed-by: Mike Turquette mturque...@linaro.org Thanks. Would you like to take the arch/ patch in your tree, or should I push it through the linux-media tree along with the omap3isp patch ?

It's so nice to see one of the last ugly bits of the omap3isp driver disappear. :-) Acked-by: Sakari Ailus sakari.ai...@iki.fi Tested-by: Sakari Ailus sakari.ai...@iki.fi (On 3630 / N950.) -- Cheers, Sakari Ailus e-mail: sakari.ai...@iki.fi XMPP: sai...@retiisi.org.uk -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
