Subject: [PATCH v5 13/25] drm: kirin: Move ade crtc/plane help functions to driver_data
Date:   Tue, 20 Aug 2019 23:06:14 +0000
Message-Id: <20190820230626.23253-14-john.stultz@linaro.org>
In-Reply-To: <20190820230626.23253-1-john.stultz@linaro.org>

From: Xu YiPing <xuyiping@hisilicon.com>

As part of refactoring the kirin driver to better support
different hardware revisions, this patch moves the crtc
and plane funcs/helper_funcs to the struct kirin_drm_data.

This will make it easier to add support for new devices
via a new kirin_drm_data structure.
