Subject: [PATCH v3 4/8] of: unittest: Add test for of_dma_get_max_cpu_address()
Date: Wed, 14 Oct 2020 21:12:06 +0200 [thread overview]
Message-ID: <20201014191211.27029-5-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20201014191211.27029-1-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.
