Subject: [PATCH v2 10/11] arm64: dts: r8a77965-salvator-x: Enable DU external clocks and HDMI
Date: Fri, 27 Apr 2018 17:57:21 +0100	[thread overview]
Message-ID: <20180427165722.19445-11-kieran.bingham+renesas@ideasonboard.com> (raw)
In-Reply-To: <20180427165722.19445-1-kieran.bingham+renesas@ideasonboard.com>

The DU1 external dot clock is provided by the fixed frequency clock
generator X21, while the DU0 and DU3 clocks are provided by the
programmable Versaclock5 clock generator.

Enable the clocks, and the HDMI encoder for the M3-N Salvator-X board
and hook it up to the HDMI connector.

Based on patches from Takeshi Kihara <takeshi.kihara.df@renesas.com>

Signed-off-by: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

v2:
 - Remove LVDS clocks from DU node
 - Merge DU Clocks and HDMI enablement
