Subject: [PATCH] OMAPDSS: TFP410: use gpio_set_value_cansleep
Date: Wed, 09 May 2012 22:08:08 +0000	[thread overview]
Message-ID: <1336601288-27848-1-git-send-email-Russ.Dill@ti.com> (raw)

The Beagleboard xM gpio used for TFP410 powerdown is connected through
an I2C attached chip which means setting the GPIO can sleep. Code that
calls tfp410_power_on/off holds a mutex, so sleeping should be fine.
