Subject: [PATCH v4 11/16] MIPS: lantiq: remove old reset controller implementation
Date: Tue, 20 Jun 2017 00:26:03 +0200	[thread overview]
Message-ID: <20170619222608.13344-12-hauke@hauke-m.de> (raw)
In-Reply-To: <20170619222608.13344-1-hauke-5/S+JYg5SzeELgA04lAiVw@public.gmane.org>

This code is now replaced by a reset controller in drivers/reset/reset-
lantiq-rcu.c. The old code was never used anyway.
