Subject: [PATCH net-next V3] net: phy: marvell10g: enable WoL for 88X3310 and 88E2110
From: Voon Weifeng <weifeng.voon@...el.com>
Implement Wake-on-LAN feature for 88X3310 and 88E2110.
This is done by enabling WoL interrupt and WoL detection and
configuring MAC address into WoL magic packet registers

Change Log:
V3:
(1) Update the commit message which is suggested by Marek.
(2) Change patch title.
(3) Remove MV_V2_WOL_STS register definition where it is not used.
(4) Rename MV_V2_WOL_INTR_EN, MV_V2_WOL_CLEAR_STS and
MV_V2_WOL_MAGIC_PKT_EN.
(5) Move change log to signedoff below.
(6) Fix indention problem in code.
(7) Reorganize newly added register definition in recommeded order.
(8) Change function name from mv2110{get|set}_wol to mv3110{get|set}_wol.
(9) Fix mv3110{get|set}_wol characters exceed 80.
V2:
(1) Reviewer Marek request to rorganize code to readable way.
(2) Reviewer Rusell request to put phy_clear_bits_mmd() outside of if(){}else{}
and modify return ret to return phy_clear_bits_mmd().
(3) Reviewer Rusell request to add return on phy_read_mmd() in set_wol().
(4) Reorganize register layout to be put before MV_V2_TEMP_CTRL.
(5) Add the .{get|set}_wol for 88E3110 too as per feedback from Russell.
