2014-07-10usb: gadget: NCM: Stop RX TCP Bursts getting dropped.Jim Baxter1-7/+8
This fixes a problem with dropped packets over 16k CDC-NCM when the connection is being heavily used. The issue was that the extracted frames cloned from the received frame were consuming more memory than necessary resulting in the truesize being ~32KB instead of ~2KB, this meant there was a high chance of reaching the sk_rcvbuf limit.

This adds multi-frame support to the NCM NTB's for the gadget driver. This allows multiple network packets to be put inside a single USB NTB with a maximum size of 16kB. It has a time out of 300ms to ensure that smaller number of packets still maintain a normal latency. Also the .fp_index and .next_fp_index have been changed to .ndp_index and .next_ndp_index to match the latest CDC-NCM specification and help with maintenance.

2014-07-10usb: renesas_usbhs: gadget: fix re-enabling pipe without re-connectingYoshihiro Shimoda3-0/+13
This patch fixes an issue that the renesas_usbhs driver in gadget mode cannot work correctly even if I disabled DMAC of the driver when I used the g_zero driver and the testusb tool. When a usb cable is re-connected, the renesas_usbhs driver calls the usbhsp_flags_init() (via usbhs_hotplug() --> usbhs_mod_call(start) --> usbhsg_try_start() --> usbhs_pipe_init()). However, the driver doesn't call the usbhsp_flags_init() when usbhsg_ep_disable() is called. So, if a gadget driver calls usb_ep_enable() and usb_ep_disable() again and again, the renesas_usbhs driver will output the following log: renesas_usbhs renesas_usbhs: can't get pipe (BULK) renesas_usbhs renesas_usbhs: wrong recip request Acked-by: Kuninori Morimoto <[email protected]> Signed-off-by: Yoshihiro Shimoda <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

2014-07-09USB: PHY: tegra: Call tegra_usb_phy_close only on device removalTuomas Tynkkynen1-5/+3
tegra_usb_phy_close() is supposed to undo the effects of tegra_usb_phy_init(). It is also currently added as the USB PHY shutdown callback, which is wrong, since tegra_usb_phy_init() is only called during probing wheras the shutdown callback can get called multiple times. This then leads to warnings about unbalanced regulator_disable if the EHCI driver is unbound and bound again at runtime.

2014-07-09USB: EHCI: tegra: Fix probe order issue leading to broken USBTuomas Tynkkynen1-3/+59
The Tegra USB complex has a particularly annoying misdesign: some of the UTMI pad configuration registers are global for all the 3 USB controllers on the chip, but those registers are located in the first controller's register space and will be cleared when the reset to the first controller is asserted. Currently, this means that if the 1st controller were to finish probing after the 2nd or 3rd controller, USB would not work at all. Fix this situation by always resetting the 1st controller before doing any other setup to any of the controllers, and then never ever reset the first controller again. As the UTMI registers are related to the PHY, the PHY driver should probably reset the Tegra controllers instead, but since old device trees only have reset phandles in the EHCI nodes, do it here, which means a bit of device tree groveling. Those old DTs also won't get the reset fix from this commit, so we'll dev_warn() them, but the driver will still keep probing successfully.

2014-07-09USB: ehci-pci: USB host controller support for Intel Quark X1000Bryan O'Donoghue1-0/+25
The EHCI packet buffer in/out threshold is programmable for Intel Quark X1000 USB host controller, and the default value is 0x20 dwords. The in/out threshold can be programmed to 0x80 dwords (512 Bytes) to maximize the perfomrance, but only when isochronous/interrupt transactions are not initiated by the USB host controller. This patch is to reconfigure the packet buffer in/out threshold as maximal as possible to maximize the performance, and 0x7F dwords (508 Bytes) should be used because the USB host controller initiates isochronous/interrupt transactions.
