[PATCH v4 17/21] ARM: shmobile: kzm9g-reference: Move pinctrl mappings to device tree
From: laurent.pinchart+renesas@ideasonboard.com (Laurent Pinchart)
Date: 2013-05-21 12:14:38
Also in:
linux-devicetree, linux-sh
Subsystem:
arm port, arm/risc-v/renesas architecture, the rest · Maintainers:
Russell King, Geert Uytterhoeven, Magnus Damm, Linus Torvalds
Replace the pinctrl mappings in board code by device tree mappings. For devices that are still instantiated from board code reference the mappings as the default pin controller state to apply them at boot time.
