Subject: [PATCH v3 03/10] dt-bindings: ata: Update ahci bindings with possible per-port interrupts
Date: Fri, 22 Mar 2019 14:39:56 +0100	[thread overview]
Message-ID: <20190322134003.4893-4-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20190322134003.4893-1-miquel.raynal@bootlin.com>

Update bindings to reflect the fact that a SATA IP can either have:
- only one interrupt: in this case an 'interrupts' property is
  declared at the root of the node;
or
- each SATA port can have their own interrupt: in this case there is
  one 'interrupts' property per port/sub-node and none at the root.
