Subject: [PATCH v2 6/7] arm64: allwinner: a64: add device tree node for HDMI simplefb
Date:   Fri, 22 Jun 2018 20:45:39 +0800
Message-Id: <20180622124540.56203-5-icenowy@aosc.io>
In-Reply-To: <20180622124540.56203-1-icenowy@aosc.io>
References: <20180622124540.56203-1-icenowy@aosc.io>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

As the U-Boot bootloader now is also capable of initialize the HDMI on
A64 boards, add a simplefb device tree node for accessing the HDMI
framebuffer initialized by the bootloader.

Changes in v2:
- Dropped LCD SimpleFB as it's already added. LCD SimpleFB needs some
  fix but the fix is present when adding DE2 CCU.
