From 6696de885eaf1fa6c2104ce70216abbc87d4fd43 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Sun, 10 Jun 2018 09:29:51 -0500 Subject: [PATCH] gpio: omap_gpio: Convert to auto-alloc feature when DT is supported The omap_gpio driver has a TODO that says when every board is converted to DM and DT, the omap_gpio_bind can stop using calloc and switch to auto-alloc. This patch converts this driver to auto-calloc when DT is enabled.
