Subject: [PATCH 2/2] ARM: imx: add lvds1_in and lvds2_in clocks
Date: Tue, 26 Aug 2014 16:58:22 +0800 [thread overview]
Message-ID: <1409043502-29081-2-git-send-email-shawn.guo@freescale.com> (raw)
In-Reply-To: <1409043502-29081-1-git-send-email-shawn.guo@freescale.com>
The lvds_in clocks are coming from external clock source via pad ANACLK.
Since lvds_in and lvds_gate clocks cannot be enabled simultaneously, we
need to call imx_clk_gate_exclusive() to register these clocks.
