The Davinci MDIO hwod perform only one function now - registers "fck"
clock alias for MDIO functional clock. From all other points of view
it's fake: it's part of cpsw and do not have clkctrl or sysc
registers.
Hence, its safe to remove it now, because "fck" clock is added
in DT for Davinci MDIO node explicitly.
I think you're right here. At least dra7 has just a single module
for cpsw at 0x48484000, ap 3 10.0, size 0x4000. I'll check the
other SoCs too.
Yeah it seems we only have one module for all the cpsw related
IP blocks.
So are these safe to apply in whatever order?
Patch 1 should go first.
but do you agree with comment I've added in patch 1:
>>>
RFC: because it will break DT ABI, mdio will not work on devices with
old DTs and new kernel which still do have [ti,hwmods = "davinci_mdio"]
property defined in DT:
