2017-10-04usb/phy-isp1301-omap: Remove .data assignmentKees Cook1-1/+0
The .data assignment appears to be redundant to the WORK_STOP bit for stopping the timer. Also, it appears this timer is entirely unused as it is only ever started under #define VERBOSE, which is explicitly undefined.

This pull request is, however, all over the place. Most of the changes are in the bdc driver adding support for USB Phy layer and PM. Renesas adds support for R-Car H3 ES2.0 and R-Car M3-W SoCs. Also here is PM_RUNTIME support for dwc3-keystone. UDC Core got a DMA unmap fix to make sure we only unmap requests that were, indeed, mapped. Other than these, we have a lot of cleanups, many of them adding 'const' to several places.
2017-08-15usb: phy: Add USB charger supportBaolin Wang1-0/+272
This patch introduces the usb charger support based on usb phy that makes an enhancement to a power driver. The basic conception of the usb charger is that, when one usb charger is added or removed by reporting from the extcon device state change, the usb charger will report to power user to set the current limitation. Power user can register a notifiee on the usb phy by issuing usb_register_notifier() to get notified by charger status changes or charger current changes. we can notify what current to be drawn to power user according to different charger type, and now we have 2 methods to get charger type. One is get charger type from extcon subsystem, which also means the charger state changes. Another is we can get the charger type from USB controller detecting or PMIC detecting, and the charger state changes should be told by issuing usb_phy_set_charger_state().

The regulator_bulk_data pointer passed to devm_regulator_bulk_get() is used to store the client handles for the regulators, which is later used by devm_regulator_bulk_release() to free the regulators. Passing a local array as is done here means the memory used to store the handles is freed causing the handles to be corrupted, resulting in a crash when devm_regulator_bulk_release() tries to free them.

2017-03-09usb: phy: isp1301: Add OF device ID tableJavier Martinez Canillas1-0/+7
The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.

2016-08-25usb: phy: generic: cope with initial stateRobert Jarzmik1-0/+2
In the gpio based case, the status of the phy is known at start by reading the VBus gpio. Actually, this is a fix, as this initial state, when not set up, prevents a gadget to answer to the enumeration phase, as there is no notification in this case (the VBus is already high when kernel boots) so no interrupt is triggered, and the flow is : - gadget initializes - gadget gets its phy-generic with a xxx_get_phy_xxx() call type - gadget does a "set_peripheral()" call type => here if the otg->state is correctly filled, the proper vbus handling will be called, and the gadget will be aware it should answer enumeration and go forth Without this fix, the USB cable must be removed and replugged for any gadget relying on phy-generic and its gpio vbus handling to work.

2016-06-21USB: Fix of_usb_get_dr_mode_by_phy with a shared phy blockHans de Goede1-1/+1
Some SoCs have a single phy-hw-block with multiple phys, this is modelled by a single phy dts node, so we end up with multiple controller nodes with a phys property pointing to the phy-node of the otg-phy. Only one of these controllers typically is an otg controller, yet we were checking the first controller who uses a phy from the block and then end up looking for a dr_mode property in e.g. the ehci controller. This commit fixes this by adding an arg0 parameter to of_usb_get_dr_mode_by_phy and make of_usb_get_dr_mode_by_phy check that this matches the phandle args[0] value when looking for the otg controller.
