2012-05-17isci: fix oem parameter validation on single controller skusDan Williams
OEM parameters [1] are parsed from the platform option-rom / efi driver. By default the driver was validating the parameters for the dual-controller case, but in single-controller case only the first set of parameters may be valid. Limit the validation to the number of actual controllers detected otherwise the driver may fail to parse the valid parameters leading to driver-load or runtime failures.

2012-05-17isci: fix interrupt disableDan Williams
There is a (dubious?) lost irq workaround in sci_controller_isr() that effectively nullifies attempts to disable interrupts. Until the workaround can be re-evaluated add some infrastructure to prevent the interrupt handler from inadvertantly re-enabling interrupts. The failure mode was interrupts continuing to run after the driver had been removed and its iomappings torn down.

2012-05-17isci: fix 'link-up' events occur after 'start-complete'Dan Williams
The call to wait_for_start() is meant to ensure that all links have been given a chance to come up before letting the kernel proceed with probing. However, the implementation is not correctly syncing with the port configuration agent. In the MPC case the ports are hard-coded, in the APC case we need to wait for the port-configuration to form ports from the started phys. Towards that end increase the timeout for the APC agent to form ports, and delay start complete until all phys are out of link-training.

2012-05-17isci: refactor initialization for S3/S4Dan Williams
Based on an original implementation by Ed Nadolski and Artur Wojcik In preparation for S3/S4 support refactor initialization so that driver-load and resume-from-suspend can share the common init path of isci_host_init(). Organize the initialization into objects that are self-contained to the driver (initialized by isci_host_init) versus those that have some upward registration (initialized at allocation time asd_sas_phy, asd_sas_port, dma allocations). The largest change is moving the the validation of the oem and module parameters from isci_host_init() to isci_host_alloc(). The S3/S4 approach being taken is that libsas will be tasked with remembering the state of the domain and the lldd is free to be forgetful. In the case of isci we'll just re-init using a subset of the normal driver load path.

This patch fixes a bug in the handling of FILEIO w/ underlying block_device resize operations where the original fd_dev->fd_dev_size was incorrectly being used in fd_get_blocks() for READ_CAPACITY response payloads. This patch avoids using fd_dev->fd_dev_size for FILEIO devices with an underlying block_device, and instead changes fd_get_blocks() to get the sector count directly from i_size_read() as recommended by hch.

2012-05-17USB: gpio_vbus: handle IRQ flags properlyShinya Kuribayashi
Currently, 'res->flags' handlings are wrong in three respects: * the driver _modifies_ the contents of platform data * res->flags is set up, but not used anywhere in the driver * request_irq() always takes VBUS_IRQ_FLAGS, regardless of refs->flags This patch tries to fix this with a policy: If a platform IRQ resource is available, give preference to its IRQ flag(s) over a default one (VBUS_IRQ_FLAGS).

2012-05-17USB: gpio_vbus: use cached IRQ number for consistency with the probed oneShinya Kuribayashi
gpio_vbus is designed to be able to get an IRQ number for VBUS change interrupt either (1) through platform_get_resource(IORESOURCE_IRQ) or (2) by processing gpio_to_irq(pdata->gpio_vbus), in probe() function. On the other hand, gpio_vbus_set_peripheral() and gpio_vbus_remove() are always doing gpio_to_irq(pdata->gpio_vbus) to get an IRQ number. This is not just inconsistent, but also broken. There is no guarantee that an IRQ number obtained by platform_get_resource() is equal to gpio_to_irq(pdata->gpio_vbus). Cache an IRQ number in probe() function, and use it where necessary.

2012-05-17usbcore: enable USB2 LPM if port suspend failsAndiry Xu
USB2 LPM is disabled when device begin to suspend and enabled after device is resumed. That's because USB spec does not define the transition from U1/U2 state to U3 state. If usb_port_suspend() fails, usb_port_resume() is never called, and USB2 LPM is disabled in this situation. Enable USB2 LPM if port suspend fails. This patch should be backported to kernels as old as 3.2, that contain the commit 65580b4321eb36f16ae8b5987bfa1bb948fc5112 "xHCI: set USB2 hardware LPM".

2012-05-17xhci: Add new short TX quirk for Fresco Logic host.Sarah Sharp
Sergio reported that when he recorded audio from a USB headset mic plugged into the USB 3.0 port on his ASUS N53SV-DH72, the audio sounded "robotic". When plugged into the USB 2.0 port under EHCI on the same laptop, the audio sounded fine. The device is: Bus 002 Device 004: ID 046d:0a0c Logitech, Inc. Clear Chat Comfort USB Headset The problem was tracked down to the Fresco Logic xHCI host controller not correctly reporting short transfers on isochronous IN endpoints. The driver would submit a 96 byte transfer, the device would only send 88 or 90 bytes, and the xHCI host would report the transfer had a "successful" completion code, with an untransferred buffer length of 8 or 6 bytes. The successful completion code and non-zero untransferred length is a contradiction. The xHCI host is supposed to only mark a transfer as successful if all the bytes are transferred. Otherwise, the transfer should be marked with a short packet completion code. Without the EHCI bus trace, we wouldn't know whether the xHCI driver should trust the completion code or the untransferred length. With it, we know to trust the untransferred length. Add a new xHCI quirk for the Fresco Logic host controller. If a transfer is reported as successful, but the untransferred length is non-zero, print a warning. For the Fresco Logic host, change the completion code to COMP_SHORT_TX and process the transfer like a short transfer. This should be backported to stable kernels that contain the commit f5182b4155b9d686c5540a6822486400e34ddd98 "xhci: Disable MSI for some Fresco Logic hosts." That commit was marked for stable kernels as old as 2.6.36.
