From d509ee55b6b91270b1369311e20cbc717ad7b4b4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Michael=20Niew=C3=B6hner?= Date: Thu, 14 Jan 2021 00:09:11 +0100 Subject: soc/intel/apl: drop LPC pad configuration code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Drop LPC pad configuration code since all boards now do pad configuration on their own. The comment about LPC_CLKRUNB when using eSPI is moved to `Documentation/getting_started/gpio.md`.
