Subject: [PATCH v2 0/9] irqchip: ti, sci-intr/inta: Update the dt bindings to accept different interrupt parents
Date: Tue, 21 Jul 2020 11:39:58 +0530 [thread overview]
Message-ID: <20200721061007.28324-1-lokeshvutla@ti.com> (raw)
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.

Changes since v1:
- Rebased on top of latest Linux master
- Dropped DT patches.
Intention to re-post the series is to get it in the review queue.
Thanks and regards,
Lokesh
