From 52a557d64c999400971419aed511b831c6a09ab9 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 2 May 2017 20:27:42 +0200 Subject: ARM: at91: ma5d4: Reset CAN controllers late MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The CAN controllers need slight delay between toggling of their reset line. Move this action into board_init(), otherwise timer will not be initialized and the board might hang.
