Most of the phy providers use "select" to enable GENERIC_PHY. Since select
is only recommended when the config is not visible, GENERIC_PHY is changed
an invisible option. To maintain consistency, all phy providers are changed
to "select" GENERIC_PHY and all non-phy drivers use "depends on" when the
phy framework is explicity required. USB_MUSB_OMAP2PLUS has a cyclic
dependency, so it is left as "select".

NAK.
Felipe, I dont understand your concern, could you please explain it more
detail? The logic behind the changes is that in cases where there was an
explicit dependency, I changed it to "depends on" and in other cases I
changed it to "selects". Thanks
Since GENERIC_PHY is visible from Kconfig, it would be much nicer to
avoid select altogether.
Felipe, after discussion with the maintainers, I have made GENERIC_PHY an
invisible option as part of this change. Thanks
Then, if the option is invisible, how can you "depend" on it ? It can
never be selected by poking around in Kconfig. IMO, it's
counterintuitive that you need to enable a PHY driver before you can see
your EHCI/OHCI/whatever controller listed in Kconfig.
If the controller requires PHY for it to be functional, it is okay to make
the controller depend on PHY IMHO. We want to try and minimize the usage of
'select' wherever possible or else 'select' is the most intuitive way. The
other option is just to leave the 'depends on' and let the user select PHY.
How can you 'depend' on something that the user can't select by
navigating through Kconfig ?
hmm... Actually it's selected when the user selects the PHY driver. Maybe we
should directly depend on the PHY driver instead of Generic PHY?
Thanks
Kishon
