Subject: Re: can: flexcan: problems with bus error reporting om i.MX53
Date: Mon, 28 Jul 2014 08:34:37 +0200 [thread overview]
Message-ID: <53D5EEFD.7020908@optimeas.de> (raw)
In-Reply-To: <53D29F02.8010708@optimeas.de>
For the sake of completeness I have reworked the patch based on:
b1aa1c7 can: flexcan: fix transition from and to freeze mode
in chip_{,un}freeze
If I find some spare time will have a look into the "can: berr_limit
support" series [1].
