Subject: [PATCH 19/19] clk: samsung: s5pv210: Remove legacy board support
Date: Fri, 04 Jul 2014 19:48:19 +0200
Message-id: <1404496099-26708-20-git-send-email-t.figa@samsung.com>
In-reply-to: <1404496099-26708-1-git-send-email-t.figa@samsung.com>
References: <1404496099-26708-1-git-send-email-t.figa@samsung.com>
Sender: linux-kernel-owner@vger.kernel.org

Since there is no more support for board files, this patch removes
legacy non-DT support from the clock driver as well, including
unnecessary clkdev aliases.
