Subject: [PATCH v3 00/10] USB: phy: phy-nop: Manage RESET GPIO in the driver
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.
Apart from RESET line changes this series also adds USB host support
fro beagle-xm and fixes USB OTG port on beagle.
The full series is avilable at
git://github.com/rogerq/linux.git
in branch
phy-reset
*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.
Patch 10 fixes USB OTG port on beagle.
Patches are based on v3.12-rc1
Tested leacy boot on omap3-beagle and omap3-beagle-xm
Tested DT boot on omap3-beagle, omap3-beagle-xm and omap4-panda-es
v3:
- Fix the Initial state of RESET line at probe time.
- Update hsusb3_reset line on omap5-uevm as well.
- Add patch 10 that fixes USB OTG port on beagle.
v2:
- Added RESET GPIO polarity feature
- Changed to gpio_set_value_cansleep()
cheers,
-roger
