Subject: [PATCH v2 0/3] Add managed ioremap function for shared resources

Many drivers can simplified by using devm_ioremap_resource()
instead of open coding its functionality. However, as pointed
by Wei Yongjun, that function cannot be used when memory region
is already taken. See previous discussion here:
https://www.spinics.net/lists/linux-pci/msg68495.html

To ease job of driver developers, new function for that
purpose is implemented and its usage shown on davinci
mtd driver.

Changes from previous version:
- moved function prototype in headers other way around (PATCH 1/3),
  the rest of patches was dropped.

Ladislav Michl (3):
  devres: Move devm_ioremap_resource() out of device.h
  devres: Add devm_ioremap_shared_resource()
  mtd: nand: davinci: Use devm_ioremap_shared_resource()
