[PATCH 0/2] ARM EXYNOS5 & net: add fixed phy support

[Ming Lei]

Hi,

These two patches adds fixed phy support using the fixed-link DT binding
for stmmac.

Thanks,
Ming Lei

[PATCH 1/2] ARM: exynos5440-sd5v1: switch to fixed-link DT binding

[Ming Lei]

The previous dts property isn't standard way for fixed phy
support, and switch to the fixed-link DT binding.
