Message-ID: <20140721190614.GB20027@arch.cereza> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Helly everyone, Currently the mvmdio driver does not require a clock to be declared, and instead this is optional. However (almost) all the platforms that currently use it, i.e. the Armada, Kirkwood and Dove SoCs, require some clock to be enabled before the MDIO registers can be accessed. The Orion5x SoC doesn't declare any clock for neither the ethernet node, nor the MDIO node. Is that correct? Do you think we could make the clock a required property in the mvmdio devicetree node? How would that behave in the non-DT case? Thanks, -- Ezequiel Garc?a, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com
