[RFC PATCH devicetree 00/10] Do something about ls-extirq interrupt-map breakage

[Vladimir Oltean]

Currently the ls-extirq driver's use of the "interrupt-map" property is
double-broken:
- once by Rob Herring's commit 869f0ec048dc ("arm64: dts: freescale: Fix
  'interrupt-map' parent address cells")
- twice by Marc Zyngier's commit 041284181226 ("of/irq: Allow matching
  of an interrupt-map local to an interrupt controller"), later revised,
  not very elegantly, through commit de4adddcbcc2 ("of/irq: Add a quirk
  for controllers with their own definition of interrupt-map"). So this
  part works but we're on an offender list.

Mark suggests that the problem may lie with the ls-extirq driver, and
its interpretation of the "interrupt-map" property, to be exact.

This set of changes attempts to make the problem smaller by using a
vendor-specific name for the property, and reverts Rob's patch because
similarity with "interrupt-map" isn't actually a desirable feature after
all, it seems.

Vladimir Oltean (10):
  irqchip/ls-extirq: rename "interrupt-map" OF property to
    "fsl,extirq-map"
  Revert "arm64: dts: freescale: Fix 'interrupt-map' parent address
    cells"
  dt-bindings: ls-extirq: replace "interrupt-map" documentation with
    "fsl,extirq-map"
  arm64: dts: ls1043a: rename the "interrupt-map" of the extirq node to
    "fsl,extirq-map"
  arm64: dts: ls1046a: rename the "interrupt-map" of the extirq node to
    "fsl,extirq-map"
  arm64: dts: ls1088a: rename the "interrupt-map" of the extirq node to
    "fsl,extirq-map"
  arm64: dts: ls208xa: rename the "interrupt-map" of the extirq node to
    "fsl,extirq-map"
  arm64: dts: lx2160a: rename the "interrupt-map" of the extirq node to
    "fsl,extirq-map"
  ARM: dts: ls1021a: rename the "interrupt-map" of the extirq node to
    "fsl,extirq-map"
  dt-bindings: ls-extirq: add a YAML schema for the validator
