[PATCH net-next v4 0/4] net: fec: fix refclk enable for SMSC LAN8710/20

[Richard Leitner <dev-M/VWbR8SM2SsTnJN9+BGXg@public.gmane.org>]

From: Richard Leitner <richard.leitner-WcANXNA0UjBBDgjK7y7TUQ@public.gmane.org>

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

This patchset depends on the "phylib: Add device reset GPIO support" patch
submitted by Geert Uytterhoeven/Sergei Shtylyov, which was merged to
net-next as commit bafbdd527d56 ("phylib: Add device reset GPIO support").

Changes v4:
	- simplify dts parsing
	- simplify reset delay evaluation and execution
	- fec: ensure to only reset once during fec_enet_open()
	- remove dependency notes from commit message
	- add reviews and acks

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
