Currently the MDIO clock is pointing to clkpa instead of clkcpgmac.
MDIO is part of the ethss and the clock should be clkcpgmac.

Santosh,
This is a big fix and needs to go in v4.2-rc. So please review and apply
asap. v4.2 is the first release that has netcp driver fully functional
and I want to fix as many known bugs as possible.
Do you have more fixes ? If yes, please post them so that I can include
them along with these two. I will try to send them up next week.
I think we have got most of the know issues fixed in the netcp driver
and dts for v4.2-rc. Another lingering issue is the one with multiple
clock handling not supported in run time pm API causing us to use the
work around 'clk_ignore_unused'. Probably this needs to be addressed in
the future as fixing this is not trivial. Generic PD support would
partially solve the issue for Keystone, but also needs to handle
multiple clocks for keystone.
Another option is to fix the NetCP and QMSS/KNAV driver for now in
v4.0-rc using explicit clock APIs so that we don't have to use
'clk_ignore_unused'. And then migrate all of the drivers to run time PM
API later when proper framework is implemented along with K2G support.
Does this make sense?
Anyways, please submit these patches at your earliest opportunity.
Thanks
Murali
Thanks !!

Santosh
