[PATCH v5 0/3] ARM: uniphier: add outer cache support and rework SMP operations

[Masahiro Yamada]

Hi Olof,

Now Linux 4.3-rc1 is out, so I am back to this.

1/3: add outer cache support
2/3: rework SMP operations
3/3: add device tree nodes

Because 2/3 highly depends on 1/3, I hope whole of this series
is applied through ARM-SOC tree.


Changes in v5:
  - Add __init to __uniphier_cache_set_locked_ways() function

Changes in v4:
  - Add more detailed comments to explain why no spin lock is needed
  - Add two examples to the binding document

Changes in v3:
  - Drop bogus includes

Changes in v2:
  - Use pr_fmt() to have pr_<level> are automatically prefixed
  - Re-design to initialize the outer cache earlier in init_IRQ()
  - Require DT properties such as "cacne-unified", "cache-size",
    "cache-sets", "cache-size", "cache-line-size".
  - Follow "next-level-cache" property to search further outer caches

  ARM: uniphier: add outer cache support
  ARM: uniphier: rework SMP operations to use trampoline code
  ARM: dts: uniphier: add outer cache controller nodes
