Oh right, we now need to always select it. Will queue this for
fixes after the merge window. The other one I'll be queueing
for v5.13 as the merge window is about to open and I'll only
queue fixes for the next few weeks :)

Regards,

Tony

"- MICREL_PHY no longer selected."

I do not agree with above as MICREL_PHY is selected by KS8851, but on many boards there is no
explicit dependency from KS8851, but MICREL PHYs are in use.
So, I'd prefer to have it enabled explicitly in omap2plus_defconfig.

And not sure what exactly "no longer selected" means.

"no longer selected" means it went away after `make savedefconfig`.

Grgorii, maybe send a patch selecting MICREL_PHY in the Kconfig
for the other cases that do not use KS8851?

The KS8851 config was added like 10years ago and is used on some omap4 platforms,
it does select MICREL_PHY.

 From other side, *some* am57x, am437 platforms uses MICREL PHYs with no dependency from KS8851.

The omap2plus_defconfig is also used as base for custom configs and first thing people are doing -
remove not needed options. As result, removal of KS8851 plus this patch will immediately
cause MICREL_PHY=n and so breakage on existing and custom platforms.

I do not see how it can be resolved by using Kconfig changes within much-omap2.

So, sry, but NACK for this patch as it is.

if some Kconfig dependencies need to be sorted out - probably the best way might be
to get rid of select MICREL_PHY in KS8851/KS8851_MLL.

We can wait on this patch no problem while we figure this out.
But certainly we need to fix things so make savedefconfig
produces valid configs that don't need to be manually edited.

That will potentially break things too as the configs now expect
it to be selected :) Looks like that got changed with commit
f0791b92d2b6 ("net: ks8851: Select PHYLIB and MICREL_PHY in
Kconfig").

So why can't we do similar patches to select MICREL_PHY for
the other non-ks8851 configurations in drivers/net/ethernet
Kconfig files as needed?

Tony

Yah. It's really has to be "depends on".

because there is no dependency between Ethernet controller (CPSW) and
Ethernet PHY - any MII capable PHY can be used with CPSW.

Yeah that's almost always better than select for sure.

OK thanks for the info.
