From 5915a2ad0da6086892c587442d4eabd681f987b5 Mon Sep 17 00:00:00 2001 From: Simon Glass <sjg@chromium.org> Date: Wed, 22 Oct 2014 21:37:09 -0600 Subject: dm: omap: gpio: Support driver model Add driver model support to this driver, while retaining support for the legacy system. Driver model GPIO support is enabled with CONFIG_DM_GPIO as usual. Since gpio_is_valid() no longer exists, we can use the -EINVAL error returned from gpio_request().
