Subject: [PATCH v2 06/11] PCI: dwc: pcie-kirin: simplify Kirin 970 get resource logic
Date: Wed,  3 Feb 2021 08:01:50 +0100
Message-ID: <360a7aec5005ccb0ce3bed3795b848288286e3f2.1612335031.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1612335031.git.mchehab+huawei@kernel.org>

Use devm_platform_ioremap_resource_byname() in order to simplify the
logic and to make the logic for Kirin 970 similar to the one for Kirin
960.
