Subject: [PATCH v4 03/10] dt-bindings: ata: Update ahci bindings with possible per-port interrupts
Date: Tue, 21 May 2019 16:30:16 +0200 [thread overview]
Message-ID: <20190521143023.31810-4-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20190521143023.31810-1-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.
