Subject: [PATCH v7 4/7] of: unittest: Add test for of_dma_get_max_cpu_address()
Date: Thu, 19 Nov 2020 18:53:56 +0100	[thread overview]
Message-ID: <20201119175400.9995-5-nsaenzjulienne@suse.de> (raw)
In-Reply-To: <20201119175400.9995-1-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>
Reviewed-by: Rob Herring <robh@kernel.org>

Changes since v5:
- Update address expected by test

Changes since v3:
 - Remove HAS_DMA guards
