It does look useful, but on the other hand, I'm wondering why it hasn't been enabled by framework by default. Sascha, what's your take on this?

I also like to have debugfs support enabled in the defconfigs. I don't know if it's desirable to enable this unconditionally when CONFIG_DEBUGFS is enabled because I think the clk debugfs support can have some bad influence on performance. I think Fabios patches are fine for nor. If we decide to enable clk debugfs support later unconditionally than all we have is two unused lines in the defconfigs. Sascha

Could you skip the imx patch? I also have some patches for the defconfig from Fabio and I'd like to squash them together since the imx defconfig could use a general update. Sascha
