2013-01-18usb: dwc3: remove dwc3 dependency on host AND gadget.Vivek Gautam
DWC3 controller curretly depends on USB && USB_GADGET. Some hardware may like to use only host feature on dwc3, or only gadget feature. So, removing this dependency of USB_DWC3 on USB and USB_GADGET. Adding the mode of operaiton of DWC3 also here HOST/GADGET/DUAL_ROLE based on which features are enabled. [ balbi@ti.com : . make sure we have default modes for all possible Kernel configurations. . Remove the config -> menuconfig change as it's unnecessary . switch over to IS_ENABLED() ] CC: Doug Anderson <dianders@chromium.org> Signed-off-by: Vivek Gautam <gautam.vivek@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-01-18powernow-k8: Add a kconfig dependency on acpi-cpufreqBorislav Petkov
Andreas reports in https://bugzilla.kernel.org/show_bug.cgi?id=51741 that with his Gentoo config, acpi-cpufreq wasn't enabled and powernow-k8 couldn't handoff properly to acpi-cpufreq leading to running without P-state support (i.e., cores are constantly in P0). To alleaviate that, we need to make powernow-k8 depend on acpi-cpufreq so that acpi-cpufreq is always present.

2013-01-18ACPI / cpuidle: Fix NULL pointer issues when cpuidle is disabledKonrad Rzeszutek Wilk
If cpuidle is disabled, that means that: per_cpu(acpi_cpuidle_device, pr->id) is set to NULL as the acpi_processor_power_init ends up failing at retval = cpuidle_register_driver(&acpi_idle_driver) (in acpi_processor_power_init) and never sets the per_cpu idle device.

I am not sure, why I found it during SG debugging. But, I noticed that even when req_queued list was empty, there were some request in request_list having queued flag true. If I run test second time, it first removes all request from request_list and hence busy_slot was wrongly incremented.

To work with scatter gather properly, fixes have been done in number of functions. I will explain requirement of each fixes one by one. start_slot: used to retrieve all request of SG during cleanup dwc3_gadget_giveback: We need to skip link TRB if it was one of the intermediate TRB of SG. dwc3_prepare_one_trb: We need to track all submitted TRBs during cleanup. Since, all TRBs would be serially allocated, so we can just keep starting slot info and we can always find rest of them. We need to pass sg node number, so that we cab appropriately program ISOC_FIRST/ISOC, Chain etc. dwc3_prepare_trbs: last_one should be set when it is last node of SG as well as last node of request_list. __dwc3_cleanup_done_trbs: It has been prepared after re-factorization of dwc3_cleanup_done_reqs.

2013-01-18usb: dwc3: gadget: fix isoc END TRANSFER ConditionPratyush Anand
There were still some corner cases where isoc transfer was not able to restart, specially when missed isoc does not happen , and in fact gadget does not queue any new request during giveback. Cleanup function calls giveback first, which provides a way to queue another request to gadget. But gadget did not had any data. So , it did not call ep_queue. To twist it further, gadget did not queue till cleanup for last queued TRB is called. If we ever reach this scenario, we must call END TRANSFER, so that we receive a new xfernotready with information about current microframe number. Also insure that there is no request submitted to core when issuing END TRANSFER.

2013-01-18usb: dwc3: gadget: fix missed isocPratyush Anand
There are two reasons to generate missed isoc. 1. when the host does not poll for all the data. 2. because of application-side delays that prevent all the data from being transferred in programmed microframe. Current code was able to handle first case only. This patch handles scenario 2 as well.Scenario 2 sometime may occur with complex gadget application, however it can be easily reproduced for testing purpose as follows: a. use isoc binterval as 1 in f_sourcesink. b. use pattern=0 c. introduce a delay of 150us deliberately in source_sink_complete, so that after few frames it lands into scenario 2. d. now run testusb 16 (isoc in test). You will notice that if this patch is not applied then isoc transfer is not able to recover after first missed. Current patch's approach is as under: If missed isoc occurs and there is no request queued then issue END TRANSFER, so that core generates next xfernotready and we will issue a fresh START TRANSFER. If there are still queued request then wait, do not issue either END or UPDATE TRANSFER, just attach next request in request_list during giveback. If any future queued request is successfully transferred then we will issue UPDATE TRANSFER for all request in the request_list.

This patch fixes the following: WARNING: vmlinux.o(.text+0x1e709c): Section mismatch in reference from the funct ion dma_controller_create() to the function .init.text:cppi_controller_start() The function dma_controller_create() references the function __init cppi_controller_start(). This is often because dma_controller_create lacks a __init annotation or the annotation of cppi_controller_start is wrong. This warning is there due to the deficiency in the commit 07a67bbb (usb: musb: Make dma_controller_create __devinit). Since the start() method is only called from musb_init_controller() which is not annotated, drop '__init' annotation from cppi_controller_start() and also cppi_pool_init() since it gets called from that function, to avoid another section mismatch warning...

Currently we're allocating an entire page to serve as our event buffer. Provided our events are 4 bytes long, it's very unlikely we will even trigger 1k events at once. Even in the worst case scenario where every endpoint triggers one event and we still have a couple of error events, that would still be less than 40 events. In order to cope with future versions of the IP which could (or could not) increase the amount of possible events to trigger simultaneously, we're using an arbitrary size of 64 events for our event buffer. We're saving 3840 bytes by doing so. Signed-off-by: Felipe Balbi <balbi@ti.com>

Add support for the UART device present in Broadcom TruManage capable NetXtreme chips (ie: 5761m 5762, and 5725). This implementation has a hidden transmit FIFO, so running in single-byte interrupt mode results in too many interrupts. The UART_CAP_HFIFO capability was added to track this. It continues to reload the THR as long as the THRE and TSRE bits are set in the LSR up to a specified limit (1024 is used here).

2013-01-17pty: return EINVAL for TIOCGPTN for BSD ptysJiri Slaby
Commit bbb63c514a3464342967237a51a21ea8f61ab951 (drivers:tty:fix up ENOIOCTLCMD error handling) changed the default return value from tty ioctl to be ENOTTY and not EINVAL. This is appropriate. But in case of TIOCGPTN for the old BSD ptys glibc started failing because it expects EINVAL to be returned. Only then it continues to obtain the pts name the other way around. So fix this case by explicit return of EINVAL in this case.

2013-01-17staging: vt6656: Fix inconsistent structure packingBen Hutchings
vt6656 has several headers that use the #pragma pack(1) directive to enable structure packing, but never disable it. The layout of structures defined in other headers can then depend on which order the various headers are included in, breaking the One Definition Rule. In practice this resulted in crashes on x86_64 until the order of header inclusion was changed for some files in commit 11d404cb56ecd ('staging: vt6656: fix headers and add cfg80211.'). But we need a proper fix that won't be affected by future changes to the order of inclusion. This removes the #pragma pack(1) directives and adds __packed to the structure definitions for which packing appears to have been intended.

2013-01-17usb: musb: Double buffering issues in host mode TXsupriya karanth
Whenever an URB is programmed for transfer, the TXFIFO is flushed. This results in valid packets of the previous transfer to get flushed when double buffering is enabled (The MUSB_TXCSR_FIFONOTEMPTY bit in TXCSR is set indicating that a packet in the FIFO is yet to be sent) For ex:- In Host mode Audio, noise is heard in the headset when double buffering is enabled on the ISO endpoint. The fifo flush is removed for double buffering case. The fifo is now flushed only in cases of error or when aborting a transfer. Also, In Host MSC case, data toggle errors are seen when double buffering is enabled on the bulk endpoint. Whenever an URB is programmed for transfer, the data toggle is set manually resulting in data toggle errors on the bus. Leave the data toggle handling upto the hardware in the double buffering case.
