[PATCH v2 0/8] Cache-coherent DMA access using UIO

From: Anup Patel
Date: Mon Jul 18 2016 - 05:14:27 EST

The goal of this patchset is to improve UIO framework and UIO dmem
driver to allow cache-coherent DMA accesses from user-space.

This patchset is based on two previous patchsets:
1) [PATCH v5 0/6] UIO driver for APM X-Gene QMTM
(Refer, http://www.spinics.net/lists/devicetree/msg58244.html)
2) [PATCH 0/4] Fix and extend uio_dmem_genirq
(Refer, https://lkml.org/lkml/2016/5/17/141)

We have adopted only patch0-3 of patchset1 which was abandoned
long time back. We have taken care of last few unaddressed comments
on these patches.

The patchset2 is quite recent has been adopted entirely. We have
taken care review comments on these patches too.

This patchset is based on v4.7-rc7 tag and it is available in uio-v2
branch of https://github.com/Broadcom/arm64-linux.git

Changes since v1:
- Make patch5 as first patch1 and mark it for linux-stable
- Get UIO dmem dynamic region details as module parameter instead
of getting it from DT node
