[PATCHv5 0/7] phy: simplified phy lookup

[Heikki Krogerus]

This set will in practice just separate the creation of a phy and
binding of it to the consumer. Mapping phys to consumers can be now
done with lookups similarly how clocks can be mapped in clkdev.c.

Vivek needs to handle the phys of dwc3 also in xhci driver on
Exynos5420 SoC, so I'm resending these now.

Changes since v4:
- Support for static lookups is dropped. The lookups can be now only
  be created with phy_create_lookup()

Changes since v3:
- We can't rely on the order in which the phys are registered, so
  using the name of the parent of the phy instance for matching
  instead of the phy itself. The parent device is always the actual
  physical device.
- Using PHY_LOOKUP macro in twl-common.c as suggested by Kishon.

Changes since v2:
- Calling ida_simple_remove in release function as pointed out by Greg

[PATCHv5 6/7] base: platform: name the device already during allocation

[Heikki Krogerus]

The device name is usually required when assigning resources
like clocks to platform devices. The problem is that the
device name is not know before platform_device_add is called
and that can be too late as the drivers may have already
requested the resources when the function returns. By naming
the device already in platform_device_alloc, the resources
can be assigned before platform_device_add is called.

This change allows different kinds of probe drivers to pass
forward their resources to the actual driver. The first
place where we need it is dwc3 controllers host glue code
(drivers/usb/dwc3/host.c) to pass the phy's to xhci.

Are you fine with this change? Can it come via linux-phy tree?

I think this patch missed getting into 3.19 or 20 now.
Is there some other tree where it got pulled in, coz i can't see it in
linux-next also ?

[PATCHv5 7/7] usb: dwc3: host: convey the PHYs to xhci

[Heikki Krogerus]

On some platforms a PHY may need to be handled also in the
host controller driver. Exynos5420 SoC requires some "PHY
tuning" based on the USB speed. This patch delivers dwc3's
PHYs to the xhci platform device when it's created.

This set of patches work fine for me.
Tested on usb-next with this series and my series for 5420 phy calibration:
[PATCH v7 0/2] Fine tune USB 3.0 PHY on exynos5420
https://lkml.org/lkml/2014/10/31/266

If you want here's my tested-by, again for entire series.
