[PATCH v3 00/20] Allow compile-testing NO_DMA (drivers)

[PATCH v3 00/20] Allow compile-testing NO_DMA (drivers)

[Geert Uytterhoeven]

        Hi all,

As of v4.17-rc1, patch series "[PATCH v2 0/5] Allow compile-testing
NO_DMA (core)" (https://lkml.org/lkml/2018/3/16/435) has been included
upstream, and drivers using the DMA API can be compile-tested on
platforms selecting NO_DMA.

This follow-up patch series removes dependencies on HAS_DMA for symbols
that already have platform dependencies implying HAS_DMA, which increases
compile-coverage.

Please apply to your tree if appropriate.

Changes compared to v2:
  - Add Acked-by,
  - Rebased to v4.17-rc1, dropping applied patch for scsi/hisi_sas,
  - Handle new VIDEO_RENESAS_CEU symbol,
  - Drop obsolete note about FSL_FMAN.

Changes compared to v1:
  - Add Reviewed-by, Acked-by,
  - Drop dependency of SND_SOC_LPASS_IPQ806X on HAS_DMA,
  - Drop dependency of VIDEOBUF{,2}_DMA_{CONTIG,SG} on HAS_DMA,
  - Drop new dependencies of VIDEO_IPU3_CIO2, DVB_C8SECTPFE, and
    MTD_NAND_MARVELL on HAS_DMA,
  - Split in per-subsystem patches,
  - Split-off the core part in a separate series.

This series is against v4.17-rc1. It can also be found at
https://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k.git/log/?h=no-dma-compile-testing-v3

It has been compile-tested with allmodconfig and allyesconfig for
m68k/sun3, and has received attention from the kbuild test robot.

Thanks for applying!

[PATCH v3 01/20] ASoC: Remove depends on HAS_DMA in case of platform dependency

[Geert Uytterhoeven]

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Note:
  - The various SND_SOC_LPASS_* symbols had to loose their dependencies
    on HAS_DMA, as they are selected by SND_SOC_STORM and/or
    SND_SOC_APQ8016_SBC.

[PATCH v3 07/20] i2c: Remove depends on HAS_DMA in case of platform dependency

[Geert Uytterhoeven]

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

[PATCH v3 12/20] media: Remove depends on HAS_DMA in case of platform dependency

[Geert Uytterhoeven]

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

Note:
  - The various VIDEOBUF*DMA* symbols had to loose their dependencies on
    HAS_DMA, as they are selected by several individual drivers.

[PATCH v3 13/20] mmc: Remove depends on HAS_DMA in case of platform dependency

[Geert Uytterhoeven]

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.

[PATCH v3 20/20] usb: Remove depends on HAS_DMA in case of platform dependency

[Geert Uytterhoeven]

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.

Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.

This simplifies the dependencies, and allows to improve compile-testing.
