USB: tegra: Add resets & has-utmi-pad-registers flag to the PHY binding

2014-07-09T23:25:46+00:00

When Tegra was converted to use the standard reset bindings, the PHY was
forgotten, probably because all the resetting of the USB blocks were
done in the EHCI driver. What also went unnoticed is that resetting the
1st on-chip USB module also wipes some of the UTMI pad configuration
registers that are also used by the other USB blocks. So this fact needs
to be described in the device tree, and the driver modified not to reset
the 1st module at inappropriate times.

In order to stay compatible with old device trees, the USB drivers will
still function without these properties but with the old,
potentially buggy behaviour.

Pull DeviceTree updates from Rob Herring:
- Another round of clean-up of FDT related code in architecture code.
This removes knowledge of internal FDT details from most
architectures except powerpc.
- Conversion of kernel's custom FDT parsing code to use libfdt.
- DT based initialization for generic serial earlycon. The
introduction of generic serial earlycon support went in through the
tty tree.
- Improve the platform device naming for DT probed devices to ensure
unique naming and use parent names instead of a global index.
- Fix a race condition in of_update_property.
- Unify the various linker section OF match tables and fix several
function prototype errors.
- Update platform_get_irq_byname to work in deferred probe cases.
- 2 binding doc updates

Pull USB driver updates from Greg KH:
 "Here is the big USB driver pull request for 3.16-rc1.

  Nothing huge here, but lots of little things in the USB core, and in
  lots of drivers.  Hopefully the USB power management will be work
  better now that it has been reworked to do per-port power control
  dynamically.  There's also a raft of gadget driver updates and fixes,
  CONFIG_USB_DEBUG is finally gone now that everything has been
  converted over to the dynamic debug inteface, the last hold-out
  drivers were cleaned up and the config option removed.  There were
  also other minor things all through the drivers/usb/ tree, the
  shortlog shows this pretty well.

  All have been in linux-next, including the very last patch, which came
  from linux-next to fix a build issue on some platforms"

Documentation: dt-bindings: update xhci-platform DT binding for R-Car H2 and M2

2014-05-28T20:27:33+00:00

This commit extends the compatible string list of the xhci-platform
binding with the new "renesas,xhci-r8a7790" and "renesas,xhci-r8a7791"
compatible strings. It is used to describe the xHCI controller which
is available in the R-Car H2 and M2 SoCs.

dt: bindings: dwc2: fix required value for the phy-names property

2014-05-28T16:17:05+00:00

"7408484 usb: gadget: s3c-hsotg: enable generic phy support" introduces
generic phy support to the dwc2.txt binding and the s3c-hsotg driver
which implements support for the binding. The binding documentation
incorrectly states that the phy-names property will be "device". The
binding example, driver, and one dts user all implement the phy-names
property as requiring "usb2-phy".

Fix the dwc2.txt binding documentation to correctly specify "usb2-phy"
as the appropriate value for phy-names.

usb: usb5303: add support for reference clock specified in device tree

2014-05-27T23:19:04+00:00

USB3503 chip supports 8 values of reference clock. The value is
specified by REF_SEL[1:0] pins and INT_N line. This patch add support
for getting 'refclk' clock, enabling it and setting INT_N line according
to the value of the gathered clock. If no clock has been specified,
driver defaults to the old behaviour (assuming that clock has been
specified by REF_SEL pins from primary reference clock frequencies
table).

usb: ehci-platform: add optional reset controller retrieval

2014-05-27T22:53:01+00:00

On the Allwinner's A31 SoC the reset line connected to the EHCI IP has to
be deasserted for the EHCI block to be usable.

Add support for an optional reset controller that will be deasserted on
power off and asserted on power on.
