From f7c1d9c8a551dea1dfe50cbac4d84f949191887d Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Tue, 30 Aug 2016 19:42:38 +0200 Subject: [PATCH] apm821xx: detect sd-card media changes for the WNDR4700 The insertion or removal of the sd-card cannot be detected by the hardware itself. This is by design. To workaround this, for the WNDR4700 unload/load the dwc2 module in case the the special SD CARD GPIO line is low/high.
