2017-11-01usb: usb251xb: Fix property_u32 NULL pointer dereferenceSerge Semin1-7/+7
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 Semin1-0/+12
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 Semin1-0/+9
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 Semin1-5/+10
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 Semin1-1/+11
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.

2017-11-01usb: usb251xb: Add USB251x specific port count settingSerge Semin1-3/+21
USB251xb as well as USB2517 datasheet states, that all these hubs differ by number of ports declared as the last digit in the model name. So USB2512 got two ports, USB2513 - three, and so on. Such setting must be reflected in the device specific data structure and corresponding dts property should be checked whether it doesn't get out of available ports.

2017-11-01usb: usb251xb: Add USB2517i specific struct and IDsSerge Semin2-4/+23
There are USB2517 and USB2517i hubs, which have almost the same registers space as already supported USB251xBi series. The difference it in DIDs and in a few functions. This patch adds the USB2517/i data structures to the driver, so it would have different setting depending on the device discovered on i2c-bus.

2017-11-01usb: usb251xb: Update usb251xb bindingsSerge Semin1-14/+32
Since hub usb2517 is going to be supported by the usb251xb driver, the bindings need to be properly updated. Particularly: - add "microchip,usb2517" and "microchip,usb2517i" compatible strings. - add "boolean" description to all the properties, which really accept a boolean value including a new one "led-{usb,speed}-mode". - move reset-gpios property to the optional section. It isn't defined as required in the code and shouldn't be required at all, since hardware may handle reset pins by itself. - add new led-{usb,speed}-mode mode property. USB2517 device supports two LED modes: USB mode and speed (default) indication mode. The last one can be switched on by this property. - add {bp,sp}-max-{total,removable}-current-microamp property measured in microamp. It hasn't been defined as property before. Since the limitation specified by these parameters is hardware specific it needs to be defined in dts.

2017-11-01usb-storage: make use of srb local variableAlan Stern1-17/+17
Commit 8b52291a0743 ("usb-storage: fix deadlock involving host lock and scsi_done") added a local variable to usb_stor_control_thread() in the usb-storage driver. This local variable holds the value of us->srb, for use after the host lock has been released. But as long as we have the value in a local variable, we may as well use it instead of dereferencing the us pointer all over the place. This patch makes no functional change; it just makes the code a little shorter and a little neater.

Most of the changes are in the mtu3 driver which added support for 36-bit DMA, support for USB 3.1 and support for dual-role (along with some non-critical fixes). The dwc2 driver got a few improvements to how we handle gadget state tracking and also added support for STM32F7xx devices. Other than that, we just some minor non-critical fixes and improvements all over the place.
