[PATCH v3 0/8] drivers: add new variants of devm_platform_ioremap_resource()

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

The new devm_platform_ioremap_resource() helper has now been widely
adopted and used in many drivers. Users of the write-combined ioremap()
variants could benefit from the same code shrinkage. This series provides
a write-combined version of devm_platform_ioremap_resource() and uses it in a
relevant driver with the assumption that - just like was the case
previously - a coccinelle script will be developed to ease the transition
for others.

There are also users of platform_get_resource_byname() who call
devm_ioremap_resource() next, so provide another variant that they can use
together with two examples.

v1 -> v2:
- dropped everything related to nocache ioremap as this is going away

v2 -> v3:
- don't call platform_get_resource() as an argument of devm_ioremap_resource(),
  it actually decreases readability
- add devm_platform_ioremap_resource_byname() as another variant
