Subject: [PATCH v2 0/2] Correct Tegra20 FUSE driver DMA usage
Date: Wed, 4 Oct 2017 01:35:07 +0300 [thread overview]
Message-ID: <cover.1507068874.git.digetx@gmail.com> (raw)
Change log:
v2:
- Dropped DT patch as turned out it was incorrect and made things
work by luck.
- Now FUSE driver requests DMA channel from the APB DMA driver
utilizing DMA channel filter.
- This patchset now depends on the APB DMA driver patch that allows
DMA client to issue a non-flow controlled transfers. I haven't
included that patch to this patchset since DMA usage is broken
anyway right now. It will work once this patchset and APBDMA
patch get applied.

soc/tegra: fuse: Fix reading registers using DMA on Tegra20
soc/tegra: fuse: Explicitly request DMA channel from APB DMA driver
