Hi Arnd, Andrew, et al.

this is v3 of updates for armada-370-xp irqchip. There is one small fix,
and another patch added which was previosly sent separately.

Also I realized that I did not send to the SoC mailing list, nor to
Arnd.

As written in previous cover letter: this driver is in need of a major
refactor in order to bring it to modern standards, but that is
unfortunately currently infeasible with my time constraints.

v1 and v2 at:
  https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=863473
  https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=863707

Changes since v2:
- dropped redundant assignment during declaration in patch 4
  (bool src0 = false, src1 = false)
- added patch 5 to this series, previously sent separately

Marek Behún (1):
  irqchip/armada-370-xp: Use atomic_io_modify() instead of another
    spinlock

Pali Rohár (4):
  irqchip/armada-370-xp: Do not allow mapping IRQ 0 and 1
  irqchip/armada-370-xp: Only call ipi_resume() if IPI is available
  irqchip/armada-370-xp: Do not touch IPI registers on platforms without
    IPI
  irqchip/armada-370-xp: Add support for 32 MSI interrupts on non-IPI
    platforms
