Subject: [PATCH v5 17/25] drm: kirin: Move config max_width and max_height to driver data
Date:   Tue, 20 Aug 2019 23:06:18 +0000
Message-Id: <20190820230626.23253-18-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 max_width
and max_height values used in kirin_drm_mode_config_inita to
hardware specific driver data.

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