Subject: [PATCH v3 0/8] drivers: add new variants of devm_platform_ioremap_resource()
Date: Sun, 6 Oct 2019 07:39:08 +0200 [thread overview]
Message-ID: <20191006053916.8849-1-brgl@bgdev.pl> (raw)
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
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
