Right now attempting doing suspend/resume while root is mounted over NFS hangs on imx6ul-14x14-evk. This is happening because ksz8081 phy fixups are lost on resume.
Fix this by using equivalent devicetree properties instead of a phy fixup and handling those properties on resume in the micrel driver. Other solutions would be possible such as having a way to run phy fixups again on resume. This alternative is precisely targeted. In theory it might now be possible to remove the phy fixup from mach-imx6ul entirely but it is possible that this would break other imx6ul boards which use the same phy. The solution would be to patch their dts but it's not clear how to identify affected boards. This code is shared with imx6ull-14x14-evk but 6ull suspend needs an unrelated patch: https://lkml.org/lkml/2017/5/30/584 Leonard Crestez (2): ARM: dts: imx6ul-14x14-evk: Add ksz8081 phy properties net: phy: micrel: Restore led_mode and clk_sel on resume arch/arm/boot/dts/imx6ul-14x14-evk.dts | 6 ++++++ drivers/net/phy/micrel.c | 15 +++++++++++++++ 2 files changed, 21 insertions(+) -- 2.7.4
