Subject: [PATCH net-next v3 0/4] net: fec: fix refclk enable for SMSC LAN8710/20
Date: Tue,  5 Dec 2017 14:25:56 +0100	[thread overview]
Message-ID: <20171205132600.13796-1-dev@g0hl1n.net> (raw)

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
