I agree. The problem is that it used to be in the ti-st driver itself,
but it has been removed in a patch that says "different platforms have
begun to have their own ways to power-up/down the chip." (eccf2979
drivers/misc/ti-st: remove gpio handling).
This needs to be clarified first. I think we could use this for now and
later fix this properly (hopefully move it back to the ti-st driver).
