Subject: [PATCH 12/32] ARM: bcm2835: Replace alt0/i2s_alt[02] with standard groups.
Date: Wed,  1 Jun 2016 23:43:21 +0200	[thread overview]
Message-ID: <1464817421-8519-13-git-send-email-kraxel@redhat.com> (raw)
In-Reply-To: <1464817421-8519-1-git-send-email-kraxel@redhat.com>

From: Eric Anholt <eric@anholt.net>

Since all of these pins were documented, we can use their names to
explain what's going on.
