Xilinx changes for v2017.05 - Move to DM clk driver - Add clk support for zynq_sdhci
2017-03-07net: zynq_gem: Fix masking of supported phydev featuresNathan Rossi
When the zynq_gem driver initializes the phy it sets the supported features that the phy can support and advertise. However instead of masking the supported features such that it limits the available features it sets the phy to have the exact supported features of the zynq_gem. This is problematic as it will enable features that a phy does not have or cannot advertise. Specifically this appears as an issue when using a phy that is only capable of 10/100, but the zynq_gem driver will override this and try to enable and advertise 10/100/1000.

2016-12-02common: miiphyutil: Work and report phy address in hex in mdio cmdMichal Simek
It is confusing that mdio commands work and report phy id as decimal value when mii is working with hex values. For example: ZynqMP> mdio list gem: 21 - TI DP83867 <--> ethernet@ff0e0000 ZynqMP> mdio read ethernet@ff0e0000 0 Reading from bus gem PHY at address 21: 0 - 0x1140 ZynqMP> mii dump 21 0 Incorrect PHY address. Range should be 0-31 ... ZynqMP> mii dump 15 0. (1140) -- PHY control register -- (8000:0000) 0.15 = 0 reset U-Boot normally takes hex values that's why this patch is changing mdio command to handle hex instead of changing mii command to handle decimal values.
