* usb/dwc3:constify dev_pm_opsDoug Wilson2017-08-101-1/+1

* PM / core: Drop run_wake flag from struct dev_pm_infoRafael J. Wysocki2017-06-281-2/+1
| | | | | | | | | | | | | | | | | | The run_wake flag in struct dev_pm_info is used to indicate whether or not the device is capable of generating remote wakeup signals at run time (or in the system working state), but the distinction between runtime remote wakeup and system wakeup signaling has always been rather artificial. The only practical reason for it to exist at the core level was that ACPI and PCI treated those two cases differently, but that's not the case any more after recent changes. For this reason, get rid of the run_wake flag and, when applicable, use device_set_wakeup_capable() and device_can_wakeup() instead of device_set_run_wake() and device_run_wake(), respectively.

* ACPI: Switch to use generic guid_t in acpi_evaluate_dsm()Andy Shevchenko2017-06-071-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16 bytes. Instead we convert them to use guid_t type. At the same time we convert current users. acpi_str_to_uuid() becomes useless after the conversion and it's safe to get rid of it. Acked-by: Rafael J.

* usb: dwc3: pci: make better use of gpiod APIUwe Kleine-König2015-07-291-10/+16
| | | | | | | | | | | | | | | | | | Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Use this additional parameter and the _optional variant to simplify the driver and improve error handling. Also expand the comment to explain why it's not sensible to switch to devm_gpiod_get and why the gpiod_put is also necessary. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.
