From a2416238368839a25be0daa6c591b5102240975b Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Mon, 13 Mar 2017 13:53:15 +0200 Subject: [PATCH] ARM: DRA7: hwmod: Fix DCAN1 stuck in transition Add HWMOD_CLKDM_NOAUTO flag to DCAN1 module. Without this DCAN1 module remains stuck in transition after the CAN interface is brought down. This is also suggested in Errata i893 "DCAN Initialization Sequence". Add the HWMOD_CLKDM_NOAUTO to DCAN2 module as well as it is mentioned in Errata i893.
