[PATCH 06/11] ARM: nomadik: move GPIO and pinctrl to device tree
From: Linus Walleij <hidden>
Date: 2013-01-07 22:56:28
Subsystem:
arm port, arm/nomadik/ux500 architectures, pin control subsystem, the rest · Maintainers:
Russell King, Linus Walleij, Linus Torvalds
This moves the instances of the Nomadik pin controller and the Nomadik GPIO blocks (also handled by the GPIO driver) over to the device tree. A new compatible string is added to the pin control driver in the process.
