From: Richard Leitner <richard.leitner@skidata.com>

This patch series fixes the use of the SMSC LAN8710/20 with a Freescale ETH
when the refclk is generated by the FSL.

This patch depends on the "phylib: Add device reset GPIO support" patch
submitted by Geert Uytterhoeven/Sergei Shtylyov, see:
https://patchwork.kernel.org/patch/10090149/

Changes v3:
- use phylib to hard-reset the PHY
- implement reset delays in phylib
- add new phylib API & flag (PHY_RST_AFTER_CLK_EN) to determine if a PHY
is affected

Changes v2:
- simplify and fix fec_reset_phy function to support multiple calls
- include: linux: phy: harmonize phy_id{,_mask} type
- reset the phy instead of not turning the clock on and off
(which would have caused a power consumption regression)

Richard Leitner (4):
phylib: Add device reset delay support
phylib: add reset after clk enable support
net: phy: smsc: LAN8710/20: add PHY_RST_AFTER_CLK_EN flag
net: fec: add phy_reset_after_clk_enable() support
