Subject: [PATCH v2 1/2] power/reset: at91-reset: add samx7 support
Date: Wed, 18 Jan 2017 00:07:37 +0100 [thread overview]
Message-ID: <20170117230738.28257-1-alexandre.belloni@free-electrons.com> (raw)
From: Szemző András <sza@esh.hu>
Add samx7 support. It is lacking a few bits and needs a new reset function.
