From 1c97793b79cb68894d9600fee15fed7bf2d399c8 Mon Sep 17 00:00:00 2001 From: Michael Niewöhner Date: Mon, 20 Jul 2020 23:27:27 +0200 Subject: mb/system76/lemp9: gpio: add a pull-down for MODEM_CLKREQ / CNVI_CLKREQ MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit MODEM_CLKREQ / CNVI_CLKREQ has no external pull-down resistor. When there is no M.2 card populated, the pin is floating. Thus enable an internal 20K PD.
