Merge branch 'sh_eth-sw-reset' 



Sergei Shtylyov says:

====================
sh_eth: couple of software reset bit cleanups

   Here's a set of 2 patches against DaveM's 'net-next.git' repo. We can save
on the repetitive chip reset code...

[1/2] sh_eth: call sh_eth_tsu_write() from sh_eth_chip_reset_giga()
[2/2] sh_eth: reuse sh_eth_chip_reset()
====================
