* Tony Lindgren [off-list ref] [120907 11:00]:
Request pins using pinctrl framework. Only show a warning on error as some boards set the pins in the bootloader even if CONFIG_PINCTRL is enabled. Signed-off-by: Tony Lindgren <tony@atomide.com> --- Note that this has only so far been tested with the legacy non-devicetree boot as devicetree boot now has a regression issue with omap-serial.
Now also tested with devicetree case on top tty-next + Felipe's "[PATCH] serial: omap: fix DeviceTree boot. Tony
