Make the tps65010 driver use gpiolib to expose its GPIOs. Note: This patch will get merged via omap tree instead of I2C as it will cause some board updates. This has been discussed at on the I2C list: http://lists.lm-sensors.org/pipermail/i2c/2008-March/003031.html Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Cc: i2c@lm-sensors.org Signed-off-by: Tony Lindgren <tony@atomide.com>
