Many thanks for your input.

Not really a (known) reason why not using this driver.

Maybe i just wasn't aware of it. Started in 2013 with first am335x board,
and the style about pinmux setup wasn't changed over time .

Only reason for not changing this NOW is, that i have this boards
already in production and passed internal testing.
But i will look into the pinctrl driver, then convert the board and 
bring in that changes within next (internal) release.

After that i will provide some patch for changing that on all BuR am335x 
boards (brxre1, brppt1, brsmarc1).
