From ae495e844a77344fdaedbb2ad97d925d096e9f0d Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Thu, 25 Oct 2012 00:38:01 -0700 Subject: Input: egalax_ts - get gpio from devicetree The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework and don't support this API anymore. The i.MX6q sabrelite platform equips an egalax touchscreen controller, and this platform already transfered to GENERIC_GPIO framework, to support this driver, we use a more generic way to get gpio. Add a return value checking for waking up the controller in the probe function, this guarantee only a workable device can pass init.
