+Subject: [PATCH] net: phy: vitesse: add vsc8504 support
+
+This patch adds support for vsc8504 phy.
+That phy is changed owner:
+ vitesse -> microsemi -> microchip
+So is its driver in kernel was changed and rewritten.
+
+there is no need to upstream this patch.
+this vsc8504 is supported by newer kernels out of box.
+support could be enabled by CONFIG_MICROSEMI_PHY.
