Subject: [PATCH 7/9] arm64: allwinner: a64: enable ANX6345 bridge on Pinebook
Date:   Thu, 18 Oct 2018 15:33:25 +0800
Message-Id: <20181018073327.64942-8-icenowy@aosc.io>
In-Reply-To: <20181018073327.64942-1-icenowy@aosc.io>
References: <20181018073327.64942-1-icenowy@aosc.io>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Pinebook has an ANX6345 bridge connected to the RGB666 LCD output, and
the I2C controlling signals are connected to R_I2C bus.

Enable it in the device tree, and add a usable EDID from the panel's
datasheet (at least 14" Pinebook used a panel without EDID).
