Previous submission: https://lkml.org/lkml/2018/1/26/215

Split the code into moving out the core bus infrastructure separate from
the irqchip glue code. Add a Kconfig dependency on ARM_GIC_V3_ITS.
Integrate the documentation with the kernel build system.

This patchset only handles moving the fsl-mc bus core out of staging.
The remaining objects (DPBP, DPCON) and drivers (dpio, dpaa2-eth) will
be moved out in subsequent patches.

Notes:
    -v6:
      - generate patchset with rename detection enabled (GregKH)
      - add Kconfig dependecy on ARM_GIC_V3_ITS (Mark Zyngier)
    -v5:
      - split irqchip glue code to separate patch (GregKH)
      - integrate doc with the kernel build system
    -v4:
      - regenerated patch with renames detection disabled (Andrew Lunn)
    -v3:
      - rebased
    -v2:
      - group irqchip gic its glue code together with the rest (Marc Zyngier)

Move the source files out of staging into their final locations:
  -mc.h include file in drivers/staging/fsl-mc/include go to include/linux/fsl
  -source files in drivers/staging/fsl-mc/bus go to drivers/bus/fsl-mc
  -overview.rst, providing an overview of DPAA2, goes to
   Documentation/networking/dpaa2/overview.rst

Update or delete other remaining staging files -- Makefile, Kconfig, TODO.
Update dpaa2_eth and dpio staging drivers.
Add integration bits for the documentation build system.

-* Add at least one device driver for a DPAA2 object (child device of the

-     * MC firmware uprev.  The MC firmware upon which the fsl-mc

* [PATCH v6 1/2] staging: fsl-mc: Move core bus out of staging
@ 2018-02-05 14:07   ` Bogdan Purcareata
  0 siblings, 0 replies; 12+ messages in thread
From: Bogdan Purcareata @ 2018-02-05 14:07 UTC (permalink / raw)
  To: linux-arm-kernel

Move the source files out of staging into their final locations:
  -mc.h include file in drivers/staging/fsl-mc/include go to include/linux/fsl
  -source files in drivers/staging/fsl-mc/bus go to drivers/bus/fsl-mc
  -overview.rst, providing an overview of DPAA2, goes to
   Documentation/networking/dpaa2/overview.rst

Update or delete other remaining staging files -- Makefile, Kconfig, TODO.
Update dpaa2_eth and dpio staging drivers.
Add integration bits for the documentation build system.

    -v6:
      - generate patch with rename detection enabled (GregKH)
    -v5:
      - split irqchip glue code to separate patch (GregKH)
      - integrate doc with the kernel build system
    -v4:
      - regenerated patch with renames detection disabled (Andrew Lunn)
    -v3:
      - rebased
    -v2:
      - group irqchip gic its glue code together with the rest (Marc Zyngier)

* [PATCH v6 2/2] staging: fsl-mc: Move irqchip code out of staging

Now that the fsl-mc bus core infrastructure is out of staging, the
remaining irqchip glue code used (irq-gic-v3-its-fsl-mc-msi.c) goes
to drivers/irqchip.

Create new Kconfig option for irqchip code that depends on
FSL_MC_BUS and ARM_GIC_V3_ITS. This ensures irqchip code only
gets built on ARM64 platforms. We can now remove #ifdef
GENERIC_MSI_DOMAIN_OPS as it was only needed for x86.

* [PATCH v6 2/2] staging: fsl-mc: Move irqchip code out of staging
@ 2018-02-05 14:07   ` Bogdan Purcareata

Now that the fsl-mc bus core infrastructure is out of staging, the
remaining irqchip glue code used (irq-gic-v3-its-fsl-mc-msi.c) goes
to drivers/irqchip.

Create new Kconfig option for irqchip code that depends on
FSL_MC_BUS and ARM_GIC_V3_ITS. This ensures irqchip code only
gets built on ARM64 platforms. We can now remove #ifdef
GENERIC_MSI_DOMAIN_OPS as it was only needed for x86.

Is this the proper location for documentation?
The doc focuses on networking, however there's also information about fsl mc
bus, dpio.

In the future, we might want to add doc for other dpaa2 objects sitting on the
fsl mc bus:
-dpseci ("Data Path SEC Interface" - abstraction for the crypto engine)
-dpdcei ("Data Path Decompression and Compression Engine Interface")

Would these fit under networking doc folder too?

Thanks,
Horia

Yes, after internal discussions we concluded it would be the best fit, since
the end usage scenario is a networking one. So far the main user of the fsl-mc
bus and dpio is dpaa2-eth, which is an Ethernet driver. It's also next to the
previous DPAA generation driver documentation at Documentation/networking/dpaa.txt.

IMO it would make sense to place them in the same Documentation/networking/dpaa2/
folder, since they're part of the same architecture. Of course, the end location
can be changed based on later feedback.
