Subject: [PATCH v13 1/4] dt-bindings: gpu: mali-bifrost: Add Mediatek MT8183
Date: Wed, 21 Apr 2021 13:28:52 +0800	[thread overview]
Message-ID: <20210421132841.v13.1.Ie74d3355761aab202d4825ac6f66d990bba0130e@changeid> (raw)
In-Reply-To: <20210421052855.1279713-1-drinkcat@chromium.org>

Define a compatible string for the Mali Bifrost GPU found in
Mediatek's MT8183 SoCs.

Signed-off-by: Nicolas Boichat <drinkcat@chromium.org>
---

(no changes since v12)

Changes in v12:
 - binding: Fix min/maxItems logic (Rob Herring)

Changes in v11:
 - binding: power-domain-names not power-domainS-names

Changes in v10:
 - Fix the binding to make sure sram-supply property can be provided.

Changes in v6:
 - Rebased, actually tested with recent mesa driver.

Changes in v5:
 - Rename "2d" power domain to "core2"

Changes in v4:
 - Add power-domain-names description
   (kept Alyssa's reviewed-by as the change is minor)
