Hi,
Modelling the RESET line as a regulator supply wasn't a good idea
as it abuses the regulator framework and makes adaptation
code/data more complex.
Instead, manage the RESET gpio line directly in the driver.
This also makes us easy to migrate to a dedicated GPIO RESET controller
whenever it becomes available. As of now, it doesn't seem to be making
it into 3.12.
*NOTE:* As there are changes to platform data, Patch 1 needs to be shared
between the arm-soc tree and usb tree.
Patch 1 is available at repo
git://github.com/rogerq/linux.git
in branch
phy-reset-common
Patch 2 contains the phy-nop driver changes
Patches 3 and 4 adapt legacy boot code to the phy-nop driver changes.
Patches 5, 6 and 7 adapt DT data to the binding changes.
Patch 8 is cleanup of omap3-beagle DT.
Patch 9 adds USB host support to omap3-beagle-xm using the new binding.
Patches are based on v3.11-rc5.
Tested leacy boot on omap3-beagle and omap3-beagle-xm
Tested DT boot on omap3-beagle, omap3-beagle-xm and omap4-panda-es
v2:
- Added RESET GPIO polarity feature
- Changed to gpio_set_value_cansleep()
cheers,

usb: phy: nop: Add gpio_reset to platform data

ARM: OMAP2+: omap-usb-host: Get rid of platform_data from struct
usbhs_phy_data
ARM: OMAP2+: usb-host: Adapt to USB phy-nop RESET line changes
ARM: dts: omap3-beagle: Use reset-gpios for hsusb2_reset
ARM: dts: omap4-panda: Use reset-gpios for hsusb1_reset

ARM: dts: omap3-beagle: Make USB host pin naming consistent
ARM: dts: omap3-beagle-xm: Add USB Host support
The 5 DTS patches looks good to me, and I can apply them, but you need
to be sure that the driver will be merged for 3.12 as well.

Benoit
