Casting between an 'int' and a pointer causes a warning on 64-bit architectures in compile-testing this driver: drivers/phy/ralink/phy-ralink-usb.c: In function 'ralink_usb_phy_probe': drivers/phy/ralink/phy-ralink-usb.c:195:13: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast] This changes the code to cast to uintptr_t instead. This is guaranteed to do what we want on all architectures and avoids the warning. Fixes: 2411a736 ("phy: ralink-usb: add driver for Mediatek/Ralink") Acked-by:

Felipe writes: usb: changes for v4.14 merge window Not a big pull request this time around. Only 49 non-merge commits. 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.

On the Allwinner A83T SoC, the last USB PHY is an HSIC PHY. It requires two clocks instead of one. On all Allwinner SoCs that share the common USB PHY design supported by the phy-sun4i-usb driver, the first PHY is always tied to OTG, and there is at most one HSIC PHY, typically the last. In this patch we take advantage of these known constraints and store an index in the compatible-string-related config structure describing which PHY is HSIC, needing the extra hsic_12M clock.

Presently, the phy pipe clock's name is assumed to be either usb3_phy_pipe_clk_src or pcie_XX_pipe_clk_src (where XX is the phy lane's number). However, this will not work if an SoC has more than one instance of the phy. Hence, instead of assuming the name of the clock, fetch it from the DT. Reviewed-by:

For some reason only f_ncm sets up that quirk, let's setup it directly in u_ether so other network models would have that quirk applied as well.

When the gadget serial device has no associated TTY, do not pass any received data into the TTY layer for processing; simply drop it instead. This prevents the TTY layer from calling back into the gadget serial driver, which will then crash in e.g. gs_write_room() due to lack of gadget serial device to TTY association (i.e. a NULL pointer dereference).

The usb_add_gadget_udc_release() routine in the USB gadget core will sometimes but not always call the gadget's release function when an error occurs. More specifically, if the struct usb_udc allocation fails then the release function is not called, and for other errors it is. As a result, users of this routine cannot know whether they need to deallocate the memory containing the gadget structure following an error. This leads to unavoidable memory leaks or double frees. This patch fixes the problem by splitting the existing device_register() call into device_initialize() and device_add(), and doing the udc allocation in between. That way, even if the allocation fails it is still possible to call device_del(), and so the release function will be always called following an error. Signed-off-by:

bus_resume() tried to resume the same ports the bus_suspend() suspeded. This caused PLC timeouts in case a suspended device disconnected and was not in a resumable state at bus_resume(). Add a check to make sure the link state is either U3 or resuming before actually resuming the link. At the same time do some other changes such as make sure we remove wake on connect/disconnect/overcurrent also for the resuming ports, and avoid extra portsc port register writes. This improves resume time with 10ms in those PLC timeout cases where devices disconnect at suspend/resume cycle. Signed-off-by:

Save 80ms device enumeration time by increasing root hub port reset time The 50ms reset signaling time is not enough for most root hub ports. Increasing the reset time to 60ms allows host controllers to finish port reset and removes a retry causing an extra 50ms delay. The USB 2 specification requires "at least 50ms" for driving root port reset. The current msleep is exactly 50ms which may not be enough if there are any delays between writing the reset bit to host controller portsc register and phy actually driving reset. On Haswell, Skylake and Kabylake xHC port reset took in average 52-59ms The 80ms improvement comes from (40ms * 2 port resets) save at enumeration for each device connected to a root hub port. more details about root port reset in USB2 section 7.1.7.5:. "Software must ensure that resets issued to the root ports drive reset long enough to overwhelm any concurrent resume attempts by downstream devices. It is required that resets from root ports have a duration of at least 50 ms (TDRSTR). Signed-off-by:
