Subject: [PATCH -next 3/3] arm64: dts: sparx5: Add SGPIO irq support
Date: Wed, 9 Dec 2020 15:27:53 +0100	[thread overview]
Message-ID: <20201209142753.683208-4-lars.povlsen@microchip.com> (raw)
In-Reply-To: <20201209142753.683208-1-lars.povlsen@microchip.com>

This enables irq support for the SGPIO input banks, allowing SGPIO
control signals to generate interrupts based on the signal state.

This f.ex. allows the SFP driver to avoid polling of module detect, tx
fault, loss of signal etc. control signals that may be connected via
the SGPIO controller.
