This patch set adds a new API to get phy by index when multiple
phys are present. This patch is based on discussion with Arnd Bergmann
about dt bindings for multiple phys.
History:
v1:
- Removed null pointers on Dmitry's suggestion
- Improved documentation in commit messages
- Exported new phy api
v2:
- EHCI and OHCI platform Kconfigs select Generic Phy
to fix build errors in certain configs.
v3:
- Made GENERIC_PHY an invisible option so
that other configs can select it
- Added stubs for devm_of_phy_get_by_index
- Reformated code
Arun Ramamurthy (4):
phy: phy-core: Make GENERIC_PHY an invisible option
phy: core: Add devm_of_phy_get_by_index to phy-core
usb: ehci-platform: Use devm_of_phy_get_by_index
usb: ohci-platform: Use devm_of_phy_get_by_index

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".

Some generic drivers, such as ehci, may use multiple phys and for such
drivers referencing phy(s) by name(s) does not make sense. Instead of
inventing new naming schemes and using custom code to iterate through them,
such drivers are better of using nameless phy bindings and using this newly
introduced API to iterate through them.

Felipe, I dont understand your concern, could you please explain it more

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.

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.

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.
