The purpose of this patch series is to add DT support for the davinci ohci driver. To be able to use device tree to probe the driver, we need to remove the platform callbacks that are handling vbus and over current. The first four patches prepare the stage by allowing to use a regulator instead of the callbacks. The next three patches convert the callback users to use a regulator instead and then remove the callbacks from the driver and platform code. Finally, we add device tree bindings and support in the driver. DEPENDENCIES: This series has depends on some patches currently under review but mostly accepted: 1. [PATCH 0/3] fix ohci phy name [1] (accepted) 2. [PATCH/RFC v2 0/3] regulator: handling of error conditions for usb drivers [2] (accepted) 3. [PATCH] gpio: davinci: Use unique labels for each gpio chip [3] (review pending) Also the current davinci baranches soon to be pulled to linux-next: davinci-for-v4.10/soc davinci-for-v4.10/dt davinci-for-v4.10/defconfig davinci-for-v4.10/cleanup A branch with all the dependencies can be found here [4]. Changes form v2->v3 * drop patches that have been integrated to arch/arm * drop regulator patches which will be integrated through regulator tree * use of the accepted regulator API to get over current status * better patch separation with the use of wrappers Changes from v1->v2 * Rebased and added patch to make ohci a separate driver * Use a regulator instead of handling Gpios (David Lechner) * Add an over current mode to regulator framework * Fixed regulator is able to register for and over current irq * Added patch by Alexandre to remove build warnings * Moved global variables into private hcd structure.
