[PATCH v4 00/18] Cleanup for populate default bus

[Kefeng Wang]

This cleanup patchset cantains two parts.

Firstly, introduce a new way to populate the default bus, then, we can
drop unnecessary calls from the arch code, and do the same thing for
of_iommu_init() in [1].

Secondly, use helper of_platform_default_populate() in linux/of_platform
when possible, instead of calling of_platform_populate() with default
match table, After that, it is possible for driver code build as a module,
and no need to export of_default_bus_match_table anymore.

This patchset is based on Linux 4.6-rc5, and only test in arm/arm64 qemu
with defconfig.

Changes since v3:
- Get rid of by making of_platform_populate callable multiple times,
  sugguested by Rob Herring

Changes since v2:
- Add more acks
- Update based on v4.6-rc2, of-generic.c in sh and board-artpec6.c in arm
  are considered

Changes since v1:
- Add ack, test and review
- Remove v1 patch 14/15, the similar patch has posted and applied,

[PATCH v4 01/18] of/platform: Add common method to populate default bus

[Kefeng Wang]

The arch code calls of_platform_populate() with default match table
when it want to populate default bus.

This patch introduce a new of_platform_default_populate_init() and make it
arch_initcall_sync(it should be later than some iommu configration, eg,
of_iommu_init() and swiotlb_late_init in arm64), then we can finish above
job in common method.

In order to avoid the default bus being populated twice, simply checking
the flag of bus node whether has be set OF_POPULATED_BUS or not.

After that, we can safely remove the caller in arch code.

Btw, add debug print in of_platform_populate(), and use __func__ to
print function's name of of_platform_bus_create().

[PATCH v4 12/18] arm: use of_platform_default_populate() to populate

Use helper of_platform_default_populate() in linux/of_platform

the default match table.

[PATCH v4 12/18] arm: use of_platform_default_populate() to populate

[Kefeng Wang]

Use helper of_platform_default_populate() in linux/of_platform
when possible, instead of calling of_platform_populate() with
the default match table.

I have not tested this, but as long as the new arch-generic code takes
place at the same point in the init sequence (arch_initcall_sync), as
it seems to, I don't expect any sh-specific breakage. In general I'm
happy to see this kind of change.
