[PATCH v4 00/10] irqchip: ti, sci-intr/inta: Update the dt bindings to accept different interrupt parents

[Lokesh Vutla]

Hi Marc,
	This is continuation of the RFC patches[0] regarding the driver
updates to support for following interrupt parent connection:
- INTR -> INTR
- INTA -> GICv3
The current existing driver assumes that INTR is always connected to
GICv3 and INTA is always connected to INTR.

As discussed this change breaks the DT backward compatibility but it
allows to not depend on TISCI firmware properties in DT node. IMHO, this
will ensure that any future changes will not effect DT properties.

This series depends on the the new Yaml bindings for common TISCI[1]

Changes since v3:
- Hardcode param_count based on parent instead of reading it from DT.
- Drop storing TISCI device id in platform device id field.

Changes since v2:
- Fixed comments from Rob
- Fixed DT schema warnings.

Changes since v1:
- Rebased on top of latest Linux master
- Dropped DT patches.
