Subject: [PATCH v5 5/7] dt-bindings: ata: Update ahci bindings with possible per-port interrupts
Date: Sun, 19 Jul 2020 08:59:40 +0200 [thread overview]
Message-ID: <20200719065942.24693-6-sven.auhagen@voleatech.de> (raw)
In-Reply-To: <20200719065942.24693-1-sven.auhagen@voleatech.de>
From: Miquel Raynal <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.
