dmaengine: ioat: depends on !UML

2021-09-26T12:09:00+00:00

[ Upstream commit bbac7a92a46f0876e588722ebe552ddfe6fd790f ]

Now that UML has PCI support, this driver must depend also on
!UML since it pokes at X86_64 architecture internals that don't
exist on ARCH=um.

dmaengine: xilinx: dpdma: Add missing dependencies to Kconfig

2021-06-30T12:47:18+00:00

[ Upstream commit 32828b82fb875b06511918b139d3a3cd93d34262 ]

The driver depends on both OF and IOMEM support, express those
dependencies in Kconfig. This fixes a build failure on S390 reported by
the 0day bot.

dmaengine: ALTERA_MSGDMA depends on HAS_IOMEM

2021-06-23T12:42:40+00:00

[ Upstream commit 253697b93c2a1c237d34d3ae326e394aeb0ca7b3 ]

When CONFIG_HAS_IOMEM is not set/enabled, certain iomap() family
functions [including ioremap(), devm_ioremap(), etc.] are not
available.
Drivers that use these functions should depend on HAS_IOMEM so that
they do not cause build errors.

Repairs this build error:
s390-linux-ld: drivers/dma/altera-msgdma.o: in function `request_and_map':
altera-msgdma.c:(.text+0x14b0): undefined reference to `devm_ioremap'

misc: mic: remove the MIC drivers

2020-10-28T18:12:03+00:00

This patch removes the MIC drivers from the kernel tree
since the corresponding devices have been discontinued.

Removing the dma and char-misc changes in one patch and
merging via the char-misc tree is best to avoid any
potential build breakage.

dmaengine: xilinx: dpdma: Add the Xilinx DisplayPort DMA engine driver

2020-07-17T06:07:59+00:00

The ZynqMP DisplayPort subsystem includes a DMA engine called DPDMA with
6 DMa channels (4 for display and 2 for audio). This driver exposes the
DPDMA through the dmaengine API, to be used by audio (ALSA) and display
(DRM) drivers for the DisplayPort subsystem.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'
