Subject: [PATCH v6 12/36] drm/tests: Add RGB Quantization tests
Date: Mon, 12 Feb 2024 14:12:55 +0100 [thread overview]
Message-ID: <20240212-kms-hdmi-connector-state-v6-12-f4bcdc979e6f@kernel.org> (raw)
In-Reply-To: <20240212-kms-hdmi-connector-state-v6-0-f4bcdc979e6f@kernel.org>
The previous commit added the infrastructure to the connector state to
track what RGB Quantization should be used in a given state for an HDMI
connector.
Let's add some kunit tests to make sure it works as expected.
