2011-10-19usb/isp1760: Allow to optionally trigger low-level chip reset via GPIOLIB.Joachim Foerster3-15/+72
Properly triggering the reset wire is necessary with the ISP1761 used on Terasic DE4 Altera-FPGA boards using a NIOS2 processor, for example. This is an optional implementation for the OF binding only. The other bindings just pass an invalid GPIO to the isp1760_register() routine. Example, usage in DTS: gpios = <&pio_isp1761rst_0 0 1>; to point to a GPIO controller from within the ISP1761 node: GPIO 0, active low.

2011-10-18EHCI: workaround for MosChip controller bugAlan Stern5-8/+49
This patch (as1489) works around a hardware bug in MosChip EHCI controllers. Evidently when one of these controllers increments the frame-index register, it changes the three low-order bits (the microframe counter) before changing the higher order bits (the frame counter). If the register is read at just the wrong time, the value obtained is too low by 8. When the appropriate quirk flag is set, we work around this problem by reading the frame-index register a second time if the first value's three low-order bits are all 0. This gives the hardware a chance to finish updating the register, yielding the correct value.

There is a race, reproduced rarely if you unload the module when host finishes mass storage device initialization (reading partition table and so on): fsg_unbind() code first closes lun files then waits for worker thread to finish its work, as the result the thread may operate on already closed device with an oops and backtrace: [ 484.937225] [<b00e403c>] (touch_atime+0x4/0x140) from [<b00a1498>] (generic_file_aio_read+0x678/0x6f0) [ 484.946563] [<b00a1498>] (generic_file_aio_read+0x678/0x6f0) from [<b00d08c4>] (do_sync_read+0xb0/0xf4) [ 484.955963] [<b00d08c4>] (do_sync_read+0xb0/0xf4) from [<b00d1478>] (vfs_read+0xac/0x144) [ 484.964172] [<b00d1478>] (vfs_read+0xac/0x144) from [<af24c6a8>] (fsg_setup+0x7f4/0x900 [g_file_storage]) [ 484.973785] [<af24c6a8>] (fsg_setup+0x7f4/0x900 [g_file_storage]) from [<af24da14>] (fsg_main_thread+0x85c/0x175c [g_file_storage]) [ 484.985626] [<af24da14>] (fsg_main_thread+0x85c/0x175c [g_file_storage]) from [<b0077c48>] (kthread+0x7c/0x84) [ 484.995666] [<b0077c48>] (kthread+0x7c/0x84) from [<b002f950>] (kernel_thread_exit+0x0/0x8) [ 485.004028] Code: eaffffd0 e28dd008 e8bd8df0 e92d40f7 (e591400c) Change the order in unbind: wait for the thread first, then close the files.

Some Stellaris evaluation kits have the JTAG/SWD FTDI chip onboard, and some, like EK-LM3S9B90, come with a separate In-Circuit Debugger Interface Board. The ICDI board can also be used stand-alone, for other boards and chips than the kit it came with. The ICDI has both old style 20-pin JTAG connector and new style JTAG/SWD 10-pin 1.27mm pitch connector. Tested with EK-LM3S9B90, where the BD-ICDI board is included.

2011-10-18USB: Fix runtime wakeup on OHCIMatthew Garrett1-4/+1
At least some OHCI hardware (such as the MCP89) fails to flag any change in the host status register or the port status registers when receiving a remote wakeup while in D3 state. This results in the controller being resumed but no device state change being noticed, at which point the controller is put back to sleep again. Since there doesn't seem to be any reliable way to identify the state change, just unconditionally resume the hub. It'll be put back to sleep in the near future anyway if there are no active devices attached to it.

2011-10-18xHCI/USB: Make xHCI driver have a BOS descriptor.Sarah Sharp2-2/+50
To add USB 3.0 link power management (LPM), we need to know what the U1 and U2 exit latencies are for the xHCI host controller. External USB 3.0 hubs report these values through the SuperSpeed Capabilities descriptor in the BOS descriptor. Make the USB 3.0 roothub for the xHCI host behave like an external hub and return the BOS descriptors. The U1 and U2 exit latencies will vary across each host controller, so we need to dynamically fill those values in by reading the exit latencies out of the xHC registers. Make the roothub code in the USB core handle hub_control() returning the length of the data copied.

This patch do the following things: 1. Add header and Copyright for marvell usb driver. 2. Add mv_usb.h in include/linux/platform_data, make the driver fits all the marvell platform using the same ChipIdea usb ip. 3. Some SOC may has mutiple clock sources, so let me define it in mv_usb_platform_data and give two helper functions named udc_clock_enable/udc_clock_disable to deal with the clocks. 4. Different SOCs will have some difference in PHY initialization, so we will remove file mv_udc_phy.c and add two funtions in mv_usb_platform_data, let the platform relative driver to realize it. 5. Rewrite probe function according to the modification list above. Find it will kernel panic when probe failed. The root cause is as follows: When probe failed, the error handle may call device_unregister() which in return will call gadget_release.In current code, gadget_release have two issues: 1: the_controller is a NULL pointer. 2: if we free udc here, then the following code in probe will access NULL pointer.

2011-10-13usb: gadget: renesas_usbhs: bugfix: don't modify platform dataKuninori Morimoto3-14/+18

So, if renesas_usbhs was compiled as module, it will be hung-up on 2nd insmod. This patch fixup it.
