[PATCH v5 0/4] Fix MTRR bug for intel-lpss-pci

[Tuowen Zhao]

Some BIOS erroneously specifies write-combining BAR for intel-lpss-pci
in MTRR. This will cause the system to hang during boot. If possible,
this bug could be corrected with a firmware update.

Previous version: https://lkml.org/lkml/2019/10/14/575

Changes from previous version:

 * implement ioremap_uc for sparc64
 * split docs changes to not CC stable (doc location moved since 5.3)

Tuowen Zhao (4):
  sparc64: implement ioremap_uc
  lib: devres: add a helper function for ioremap_uc
  mfd: intel-lpss: use devm_ioremap_uc for MMIO
  docs: driver-model: add devm_ioremap_uc
