Subject: [PATCH] soc: ti: Use devm_platform_ioremap_resource_byname
Date:   Fri, 23 Apr 2021 17:04:09 +0800
Message-Id: <20210423090409.25032-1-dingsenjie@163.com>

From: dingsenjie <dingsenjie@yulong.com>

Use the devm_platform_ioremap_resource_byname() helper instead of
calling platform_get_resource_byname() and devm_ioremap_resource()
separately
