From 9ab66d0d207451a834a7995a45c018a6395fc160 Mon Sep 17 00:00:00 2001 From: Ludovic Desroches <ludovic.desroches@microchip.com> Date: Mon, 23 Apr 2018 10:59:50 +0300 Subject: [PATCH] board: atmel: sama5d2_ptc_ek: update pin configuration for NAND The drive strength has to be set to medium for the NAND data lines. With a low drive, we can get some data corruption.
