Subject: [PATCH v4 6/7] RFC: drm/panfrost: Add mt8183-mali compatible string
Date:   Fri,  7 Feb 2020 13:26:26 +0800
Message-Id: <20200207052627.130118-7-drinkcat@chromium.org>
In-Reply-To: <20200207052627.130118-1-drinkcat@chromium.org>

Precedence: bulk

For testing only, the driver doesn't really work yet, AFAICT.

v4:
 - Add power domain names.
v3:
 - Match mt8183-mali instead of bifrost, as we require special
   handling for the 2 regulators and 3 power domains.
