Subject: [PATCH 09/12] ARM: ux500: delete custom pin control system
From: Linus Walleij <linus.walleij@...aro.org>
At the beginning of the first patch series I included the custom
ux500 pin control system to make sure I could eventually replace
it with the standard subsystem driver. So now that we've done so,
let's remove it.
