[RFC PATCH] usb: gadget: composite Allow for larger configuration descriptors

The composite framework allows us to create gadgets composed from many different functions, which need to fit into a single configuration descriptor. Some functions (like uvc) can produce configuration descriptors upwards of 2500 bytes on their own. This patch increases the limit from 1024 bytes

[RFC PATCH] usb: gadget: composite Allow for larger configuration descriptors

I have been doing some work with uvc gadgets, which mirrors the capabilities of actual webcams attached to a host port. During testing I ran into -EPIPE errors when trying to retrieve configurations for more complex devices. I tracked the errors down to running over the rather conservative buffer

[PATCH V2 3/3] usb: xhci: tegra: Add support for managing powergates

The Tegra XHCI controller requires that the XUSBA (for superspeed) and XUSBC (for host) power-domains are enabled. Commit 8df127456f29 ("soc/tegra: pmc: Enable XUSB partitions on boot") was added to force on these power-domains if the XHCI driver is enabled while proper power-domain support is

[PATCH V2 1/3] usb: xhci: tegra: Prepare for adding runtime PM support

When adding runtime PM support to the Tegra XHCI driver, it is desirable to move the function calls to enable the clocks, regulators and PHY from the tegra_xusb_probe into the runtime PM handlers. Currently, the clocks, regulators and PHY are all enabled before we call usb_create_hcd() in

[PATCH 3/3] usb: musb: host: fix potential NULL pointer dereference

musb_start_urb() doesn't check the 3rd pass-in parameter if it is NULL. But in musb_bulk_nak_timeout() the parameter passed to musb_start_urb() is returned from first_qh(), which could be NULL. So wrap the musb_start_urb() call here with a if condition check to avoid the potential NULL pointer

UDC core ensures the usb_ep parameter passed in is not NULL, so checking if (ep != NULL) is pointless. Convert to_musb_ep() to a simple macro to not directly return NULL to avoid warnings from code static analysis tools. Signed-off-by: Bin Liu --- v2: revised the parentheses.

[PATCH v2 1/3] usb: musb: gadget: fix to_musb_request() to not return NULL
