From 0c3013bbe1d80035dc58336c4c7fdb18a32931df Mon Sep 17 00:00:00 2001 From: Tan Jui Nee Date: Tue, 7 Jun 2016 14:55:51 +0800 Subject: [PATCH] pinctrl/broxton: enable platform device in the absence of ACPI enumeration This is to cater the need for non-ACPI system whereby a platform device has to be created in order to bind with the Apollo Lake Pinctrl GPIO platform driver.
