From 2c80920f66f2333dd140715450d220724af3a400 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Mon, 23 Jul 2018 19:53:01 +0200 Subject: ARM: exynos: Remove legacy setting of external wakeup interrupts Since Exynos/S5Pv210 pin-controller driver is taking care about setting the external wakeup interrupts mask, the legacy code can be removed.
