Subject: [PATCH 1/3] dt-bindings: gpio: lpc32xx: document interrupt bindings
Date: Wed, 10 Apr 2019 12:39:24 +0200 [thread overview]
Message-ID: <20190410103926.8781-2-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20190410103926.8781-1-alexandre.belloni@bootlin.com>
Some of the LPC32xx gpios are wired directly to one of the interrupt
controllers while port 0 and port 1 share the same interrupt for their
interrupt capable gpios.

+- interrupts: Should be the interrupt shared by port 0 and port 1 and the
+ interrupts for individual pins from port 3.
+- interrupt-names : Should be the names of irq resources. The shared port
