Subject: [PATCH v4 0/5] enhance configuring an ITS

This patch series makes some enhancement to ITS configuration in the
following aspects:

o make allocation of the ITS tables more sensible
o replace magic numbers with sensible macros
o guarantees a safe quiescent status before initializing an ITS

This patch series is based on Marc's branch[1], and tested on Hisilion
ARM64 board with GICv3 ITS hardware.

[1] https://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git irq/gic-fixes

v3 -> v4:
o Spell out device table instead of DT to avoid misunderstanding
o Change its_check_quiesced() to a more sensible name its_force_quiescent()

v2 -> v3:
o drop the patch of tracing LPI enabling status since Vladimir Murzin
  had already posted a similar patch
o fix several improper description issues

v1 -> v2:
o rebase to Marc's GIC fix branch
o drop size calculation for Device Table since Marc had already posted one
o guarantees a safe quiescent status before initializing an ITS as
  Marc suggested, rather than register a reboot notifier
o fix an issue about the enabling status of LPI feature

Yun Wu (5):
  irqchip: gicv3-its: zero itt before handling to hardware
  irqchip: gicv3-its: use 64KB page as default granule
  irqchip: gicv3-its: add limitation to page order
  irqchip: gicv3-its: define macros for GITS_CTLR fields
  irqchip: gicv3-its: support safe initialization
