2017-11-07USB: host: ohci: Remove redundant license textGreg Kroah-Hartman
Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

2017-11-07usbip: use monotonic timestampsArnd Bergmann
This gets rid of the deprecated do_gettimeofday() function in usbip. The comment above vgadget_get_frame() mentions that it suffers from issues with the time jumps due to suspend and settimeofday, so I'm changing it to use ktime_get_ts64() to use monotonic times that don't have this problem. I couldn't tell whether we should use CLOCK_MONOTONIC or CLOCK_MONOTONIC_RAW here, the difference being the exact rate when correcting for NTP. I picked monotonic time since it doesn't change the speed to the existing code and should be better synchronized with other machines we talk to.

2017-11-07usbip: fix off-by-one frame number calculationArnd Bergmann
vgadget_get_frame returns a frame number from 0 to 2046, which may require an expensive division operation to wrap at one lower than the usual number. I can't see any reason for this, and all other drivers wrap at a power-of-two number. My best explanation is that it was a simple typo, so I'm changing the % modulo operator into a cheaper bitmask that the other drivers use, to make it wrap after 0x7ff rather than before it.

2017-11-04USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman
It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

2017-11-02usb: xhci: tegra: use time64_t for printing timestampArnd Bergmann
The time_t type and time_to_tm() function are deprecated because of y2038 problems. In this driver, they are used to pretty-print the timestamp of the firmware build. This is fine as long as we don't get a firmware build past 2038. Converting to time64_t and time64_to_tm() avoids the deprecated interfaces and works until 2106, when the firmware-defined data structure overflows.

2017-11-01usb: usb251xb: Use GPIO descriptor consumer interfaceSerge Semin
The driver used to be developed with legacy GPIO API support. It's better to use descriptor-based interface for several reasons. First of all the legacy API doesn't support the ACTIVE_LOW/HIGH flag of dts nodes, which is essential since different hardware may have different GPIOs connectivity including the logical value inversion. Secondly, by requesting the reset GPIO descriptor the driver prevent the other applications from changing its value. And last but not least the legacy GPIO interface should be avoided in the new code due to it obsolescence.

2017-11-01usb: usb251xb: Add max power/current dts property supportSerge Semin
This parameters may be varied in accordance with hardware specifics. So lets add the corresponding settings to the usb251xb driver dts specification. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-11-01usb: usb251xb: Fix property_u32 NULL pointer dereferenceSerge Semin
The methods like of_property_read_u32 utilizing the specified pointer permit only the pointer to a preallocated u32 storage as the third argument. As a result the driver crashes on NULL pointer dereference in case if "oc-delay-us" or "power-on-time-ms" declared in dts file.

2017-11-01usb: usb251xb: Add USB2517 LED settingsSerge Semin
USB2517 supports two LED modes: USB mode and speed (default) indication mode. The last one can be switched on by corresponding dts property. Since USB251xb hubs doesn't support LEDs settings, we need to ignore this setting. Signed-off-by: Serge Semin <fancer.lancer@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-11-01usb: usb251xb: Add battery enable setting flagSerge Semin
Battery charging settings are supported by USB251xb hubs only. USB2517i isn't one of them. So we need to reflect it within the device-specific data structure. The driver doesn't support dts property changing this setting, but instead defaults it with zero. So the flag isn't used anywhere in the driver, but still can be helpful in future, when necessity of the corresponding dts setting arises.

2017-11-01usb: usb251xb: Add 5,6,7 ports boost settingsSerge Semin
USB electrical signaling drive strength boost bit is also supported by USB2517 hub. Since it got three addition ports, the designers needed to add one more register for initialization. It turned out to be formerly reserved 0xF7. As before we just initialize it with default zeros.

2017-11-01usb: usb251xb: Add 5,6,7 ports mapping def settingSerge Semin
USB2517 got three additionl downstream ports, which can as well be mapped to another logical ports. USB251xb driver currently doesn't fully support such setting configuration from dts file. This patch doesn't change this, but adds usb2517 spcific ports default liner mapping.
