[PATCH v4 0/5] drivers: new helper for ioremapping memory resources
From: Dejin Zheng
Date: Mon Mar 23 2020 - 12:06:22 EST
Since commit "drivers: provide devm_platform_ioremap_resource()",
It was wrap platform_get_resource() and devm_ioremap_resource() as
single helper devm_platform_ioremap_resource(). but now, many drivers
still used platform_get_resource() and devm_ioremap_resource()
together in the kernel tree. The reason can not be replaced is they
still need use the resource variables obtained by platform_get_resource().
so provide this helper.
The first patch in this series adds a wrapper for these two calls and
the other uses it in a driver.
v3 -> v4:
- modified the description of a parameter res in patch 1.
- modified patch 5's commit comment.
v2 -> v3:
- rename the function to
devm_platform_get_and_ioremap_resource() by Sergei's suggestion.
- make the last parameter res as optional by Geert's suggestion.
- Reimplement devm_platform_ioremap_resource by calling
devm_platform_get_and_ioremap_resource() by Geert's suggestion.
v1 -> v2:
- add some real users of this function (Thanks for greg k-h's reminder)
