Subject: [PATCH v4 4/7] of: unittest: Add test for of_dma_get_max_cpu_address()
Date: Wed, 21 Oct 2020 14:34:34 +0200 [thread overview]
Message-ID: <20201021123437.21538-5-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20201021123437.21538-1-nsaenzjulienne@suse.de>
Introduce a test for of_dma_get_max_cup_address(), it uses the same DT
data as the rest of dma-ranges unit tests.
Signed-off-by: Nicolas Saenz Julienne <nsaenzjulienne@suse.de>
