Subject: [RESEND][PATCH v3 07/26] drm: kirin: Rename ade_plane to kirin_plane
Date:   Wed, 14 Aug 2019 18:46:43 +0000
Message-Id: <20190814184702.54275-8-john.stultz@linaro.org>
In-Reply-To: <20190814184702.54275-1-john.stultz@linaro.org>
References: <20190814184702.54275-1-john.stultz@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch renames the
struct ade_plane to kirin_plane.

The struct kirin_plane will later used by both kirin620 and
future kirin960 driver, and will be moved to a common
kirin_drm_drv.h in a future patch
