first of all,thanks Heiko for ur reply.
but i m afraid that i understand nothing from ur answer,
can u give me the steps to do ur suggestion?
is ur suggestion is about to change the device tree of my board?
Here is the dts file of my board, if so what are the modifictions i have to
do to execute ur suggestions
