   3 Subject: [PATCH] net: phy: vitesse: add vsc8504 support
   4
   5 This patch adds support for vsc8504 phy.
   6 That phy is changed owner:
   7  vitesse -> microsemi -> microchip
   8 So is its driver in kernel was changed and rewritten.
   9
  10 there is no need to upstream this patch.
  11 this vsc8504 is supported by newer kernels out of box.
  12 support could be enabled by CONFIG_MICROSEMI_PHY.
