Stas Sergeev 4cba5c2103 of_mdio: add new DT property 'managed' to specify the PHY management type ... Currently the PHY management type is selected by the MAC driver arbitrary. The decision is based on the presence of the "fixed-link" node and on a will of the driver's authors. This caused a regression recently, when mvneta driver suddenly started to use the in-band status for auto-negotiation on fixed links. It appears the auto-negotiation may not work when expected by the MAC driver. Sebastien Rannou explains: << Yes, I confirm that my HW does not generate an in-band status. AFAIK, it's a PHY that aggregates 4xSGMIIs to 1xQSGMII ; the MAC side of the PHY (with inband status) is connected to the switch through QSGMII, and in this context we are on the media side of the PHY. >> https://lkml.org/lkml/2015/7/10/206 This patch introduces the new string property 'managed' that allows the user to set the management type explicitly. The supported values are: "auto" - default. Uses either MDIO or nothing, depending on the presence of the fixed-link node "in-band-status" - use in-band status Signed-off-by: Stas Sergeev <stsp@users.sourceforge.net> CC: Rob Herring <robh+dt@kernel.org> CC: Pawel Moll <pawel.moll@arm.com> CC: Mark Rutland <mark.rutland@arm.com> CC: Ian Campbell <ijc+devicetree@hellion.org.uk> CC: Kumar Gala <galak@codeaurora.org> CC: Florian Fainelli <f.fainelli@gmail.com> CC: Grant Likely <grant.likely@linaro.org> CC: devicetree@vger.kernel.org CC: linux-kernel@vger.kernel.org CC: netdev@vger.kernel.org Signed-off-by: David S.
