Changes from v2:
1) Added support for multiple PHYs (UTMI+ and PIPE3) and
related changes in the driver structuring.
I'm a bit skeptical about this separation. Can the PHY operate with just the
UTMI+ or PIPE3 part enabled alone without the other? Can any PHY consumer
operate this way?
Yes :-)
As also pointed by Kishon the PHY consumer (which is DWC3 in case of
Exynos5 SoC series)
should theoretically be able use either UTMI+ phy for High speed
operations or both (UTMI+ and PIPE3)
for Super Speed operations.
OK, that's fine then. This is the explanation I needed, thanks.
I believe the right thing to do here is to do all the initialization in
.power_on() and let the driver simply call phy_power_on() when it needs the
PHY and phy_power_off() otherwise.
If this is what we should be doing then what will be the purpose of
two separate APIs :
phy_power_on() and phy_init().
Am i missing while understanding the things.
I don't understand this separation as well. Operations that should be
done together shouldn't be separated. Is there any case when you can
call one of phy_power_on() and phy_init() without calling another one
right before/after it?
Best regards,
Tomasz
