Subject: [PATCH net-next 6/6] ixp4xx_eth: Probe the PTP module from the device tree
Date: Sun,  1 Aug 2021 02:27:37 +0200	[thread overview]
Message-ID: <20210801002737.3038741-7-linus.walleij@linaro.org> (raw)
In-Reply-To: <20210801002737.3038741-1-linus.walleij@linaro.org>

This adds device tree probing support for the PTP module
adjacent to the ethernet module. It is pretty straight
forward, all resources are in the device tree as they
come to the platform device.
