From 78238dfbbd14da6c4c4ae3185bad18564250c259 Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Sat, 17 Jun 2017 14:51:07 +0200 Subject: apalis_t30: pinmux: enable internal pull-up on mxm3 pin 37 While MXM3 pin 37 aka WAKE1_MICO is pulled up with 4.7 K on the Apalis Evaluation board and 100 K on the Ixora carrier board a custom carrier board may leave it floating which may cause an unintended high interrupt load on the default wake-up key with which may cause a lower CPU performance.
