2011-10-13usb: gadget: renesas_usbhs: tidyup INTENB0 methodKuninori Morimoto
This patch tidyup Interrupt Enable Register 0 (INTENB0) which has relationship with picky BEMPENB/BRDYENB. - add explain comment - ignore nonsense 0 write case Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-10-13usb: gadget: renesas_usbhs: struct usbhs_pipe hold handlerKuninori Morimoto
packet handler had moved to struct usbhs_pipe from struct usbhsg_uep. it is preparation of mod_host support Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-10-13usb: gadget: renesas_usbhs: each pipe hold maxpacket sizeKuninori Morimoto
Current renesas_usbhs pipe accessed DCPMAXP/PIPEMAXP register to get own maxpacket size every time. But maxpacket size isn't changed after pipe start, and register access is too slow. This patch adds new maxp variable to keep own maxpacket. And un-used function are removed.

2011-10-13usb: gadget: renesas_usbhs: remove desc from usbhs_pipe_mallocKuninori Morimoto
Current usbhs_pipe_malloc() used usb_endpoint_descriptor to get necessary information. It was very good for mod_gadget which allocate pipe in runtime, but is not good for mod_host which allocate pipe in initial timing.

2011-10-13usb: gadget: storage: fix mass storage gadgets to work with Synopsys UDCPaul Zimmerman
The Synopsys USB device controller requires all OUT transfer request lengths to be aligned to max packet size. The mass storage gadgets do not meet this requirement for Super Speed. The gadgets already have a function which performs this alignment for CBW packets, so use it for data packets too. The alternative would be to implement bounce buffers in the DWC3 driver, but that could have a significant impact on performance. This version is based upon a more-correct patch written by Alan Stern. Signed-off-by: Paul Zimmerman <paulz@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2011-10-13USB: gadget: f_midi: allow a dynamic number of input and output portsDaniel Mack
The code in the MIDI gadget was already sort of prepared for multi-port configuration, so the streaming logic itself didn't need much tweaking. However, the descriptors change when the number of ports do, and so some rework of the the preparation algorithms were necessary. Successfully tested on Linux and Max OS X hosts for both input and output streams.

2011-10-13USB: gadget: midi: add midi function driverDaniel Mack
This patch adds f_midi.c to implement a USB gadget function that works with the composite framework, so it can be combined with other USB functions. The code for the ALSA/MIDI logic was taken from the midi device gadget, other parts have been rewritten to benefit from the dynamic descriptor allocation features.

2011-09-29user namespace: usb: make usb urbs user namespace aware (v2)Serge Hallyn
Add to the dev_state and alloc_async structures the user namespace corresponding to the uid and euid. Pass these to kill_pid_info_as_uid(), which can then implement a proper, user-namespace-aware uid check. Changelog: Sep 20: Per Oleg's suggestion: Instead of caching and passing user namespace, uid, and euid each separately, pass a struct cred. Sep 26: Address Alan Stern's comments: don't define a struct cred at usbdev_open(), and take and put a cred at async_completed() to ensure it lasts for the duration of kill_pid_info_as_cred().
