[PATCH v6 00/13] 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].

Tested with: (There is a build error on Today's master while building dtbs. So I enabled
	      only the TI specific components for building DTBS).
- DT_SCHEMA_FILES="Documentation/devicetree/bindings/interrupt-controller/ti,sci-intr.yaml"
  v8make dt_binding_check
- DT_SCHEMA_FILES="Documentation/devicetree/bindings/interrupt-controller/ti,sci-inta.yaml"
  v8make dt_binding_check
- DT_SCHEMA_FILES="Documentation/devicetree/bindings/interrupt-controller/ti,sci-intr.yaml"
  v8make dtbs_check
- DT_SCHEMA_FILES="Documentation/devicetree/bindings/interrupt-controller/ti,sci-inta.yaml"
  v8make dtbs_check
- v8make allmodconfig

Changes since v5:
- Rebased on latest master.
- Collected Reviewed-by from Rob.
- Included DT changes in the same series so that everything can be merged in a single go.
  Without DT changes, there are regressions for DMA and other consumer peripherals so suggestion
  is to merge everthing in a single go. DT changes apply cleanly on next and Linus's master
  without any merge conflicts.

Changes since v4:
- Fixed Rob's comment on INTR and INTA yaml documentation
- Collected Reviewed-by's and Acked-by's

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.
