Subject: [PATCH v6 4/4] drm/panfrost: Add mt8183-mali compatible string
Date: Tue, 5 Jan 2021 08:11:19 +0800 [thread overview]
Message-ID: <20210105081111.v6.4.I5f6b04431828ec9c3e41e65f3337cec6a127480d@changeid> (raw)
In-Reply-To: <20210105001119.2129559-1-drinkcat@chromium.org>
Add support for MT8183's G-57 Bifrost.
Signed-off-by: Nicolas Boichat <drinkcat@chromium.org>
---
Changes in v6:
- Context conflicts, reflow the code.
- Use ARRAY_SIZE for power domains too.
Changes in v5:
- Change power domain name from 2d to core2.
Changes in v4:
- Add power domain names.
Changes in v3:
- Match mt8183-mali instead of bifrost, as we require special
handling for the 2 regulators and 3 power domains.
