This is a note to let you know that I've just added the patch titled net: phy: micrel: set soft_reset callback to genphy_soft_reset for KSZ8081 to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-phy-micrel-set-soft_reset-callback-to-genphy_sof.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 35619b89465f3182d211802030fc900286936b07 Author: Christian Melki <christian.melki@xxxxxxxxxx> Date: Wed Feb 24 21:55:36 2021 +0100 net: phy: micrel: set soft_reset callback to genphy_soft_reset for KSZ8081 [ Upstream commit 764d31cacfe48440745c4bbb55a62ac9471c9f19 ] Following a similar reinstate for the KSZ9031. Older kernels would use the genphy_soft_reset if the PHY did not implement a .soft_reset. Bluntly removing that default may expose a lot of situations where various PHYs/board implementations won't recover on various changes. Like with this implementation during a 4.9.x to 5.4.x LTS transition. I think it's a good thing to remove unwanted soft resets but wonder if it did open a can of worms? Atleast this fixes one iMX6 FEC/RMII/8081 combo.
