i did what you sujested and all commands worked except for the git
sendmail part so i do not know if I should still be sending you the
patch this way but here it is. i also defined the gpio keys in the dts
file like you said the same as with the iconnect but the kernel keeps
crashing with them defined in the dts is the support actualy there for
the keys? or have i just defined them wrong?
