From 6fb18d6e271b98ea355506e8dcd603c21734c3d4 Mon Sep 17 00:00:00 2001 From: Martin Vajnar Date: Wed, 24 Dec 2014 00:27:57 +0100 Subject: [PATCH] hx4700: regulator: declare full constraints commit a52d209336f8fc7483a8c7f4a8a7d2a8e1692a6c upstream. Since the removal of CONFIG_REGULATOR_DUMMY option, the touchscreen stopped working. This patch enables the "replacement" for REGULATOR_DUMMY and allows the touchscreen to work even though there is no regulator for "vcc".
