Subject: [PATCH v22 3/5] drm/mediatek: add mediatek-drm of vdosys0 support for mt8195
Date: Thu, 26 May 2022 18:21:24 +0800 [thread overview]
Message-ID: <20220526102126.19756-4-jason-jh.lin@mediatek.com> (raw)
In-Reply-To: <20220526102126.19756-1-jason-jh.lin@mediatek.com>
From: "jason-jh.lin" <jason-jh.lin@mediatek.com>
1. Add driver data of mt8195 vdosys0 to mediatek-drm and the sub driver.
2. Add get driver data function to identify which vdosys by io_start.
