2012-01-24USB: cdc-wdm: Avoid hanging on interface with no USB_CDC_DMM_TYPEBjørn Mork
The probe does not strictly require the USB_CDC_DMM_TYPE descriptor, which is a good thing as it makes the driver usable on non-conforming interfaces. A user could e.g. bind to it to a CDC ECM interface by using the new_id and bind sysfs files. But this would fail with a 0 buffer length due to the missing descriptor.

2012-01-24tty: serial: OMAP: transmit FIFO threshold interrupts don't wake the chipPaul Walmsley
It seems that when the transmit FIFO threshold is reached on OMAP UARTs, it does not result in a PRCM wakeup. This appears to be a silicon bug. This means that if the MPU powerdomain is in a low-power state, the MPU will not be awakened to refill the FIFO until the next interrupt from another device. The best solution, at least for the short term, would be for the OMAP serial driver to call a OMAP subarchitecture function to prevent the MPU powerdomain from entering a low power state while the FIFO has data to transmit. However, we no longer have a clean way to do this, since patches that add platform_data function pointers have been deprecated by the OMAP maintainer. So we attempt to work around this as well. The workarounds depend on the setting of CONFIG_CPU_IDLE. When CONFIG_CPU_IDLE=n, the driver will now only transmit one byte at a time. This causes the transmit FIFO threshold interrupt to stay active until there is no more data to be sent. Thus, the MPU powerdomain stays on during transmits. Aside from that energy consumption penalty, each transmitted byte results in a huge number of UART interrupts -- about five per byte. This wastes CPU time and is quite inefficient, but is probably the most expedient workaround in this case. When CONFIG_CPU_IDLE=y, there is a slightly more direct workaround: the PM QoS constraint can be abused to keep the MPU powerdomain on. This results in a normal number of interrupts, but, similar to the above workaround, wastes power by preventing the MPU from entering WFI. Future patches are planned for the 3.4 merge window to implement more efficient, but also more disruptive, workarounds to these problems. DMA operation is unaffected by this patch.

2012-01-24tty: serial: OMAP: ensure FIFO levels are set correctly in non-DMA modePaul Walmsley
Ensure FIFO levels are set correctly in non-DMA mode (the default). This patch will cause a receive FIFO threshold interrupt to be raised when there is at least one byte in the RX FIFO. It will also cause a transmit FIFO threshold interrupt when there is only one byte remaining in the TX FIFO. These changes fix the receive interrupt problem and part of the transmit interrupt problem. A separate set of issues must be worked around for the transmit path to have a basic level of functionality; a subsequent patch will address these. DMA operation is unaffected by this patch.

2012-01-24TTY: fix UV serial console regressionJiri Slaby
Commit 74c2107759d (serial: Use block_til_ready helper) and its fixup 3f582b8c110 (serial: fix termios settings in open) introduced a regression on UV systems. The serial eventually freezes while being used. It's completely unpredictable and sometimes needs a heap of traffic to happen first. To reproduce this, yast installation was used as it turned out to be pretty reliable in reproducing. Especially during installation process where one doesn't have an SSH daemon running. And no monitor as the HW is completely headless. So this was fun to find. Given the machine doesn't boot on vanilla before 2.6.36 final. (And the commits above are older.) Unless there is some bad race in the code, the hardware seems to be pretty broken. Otherwise pure MSR read should not cause such a bug, or? So to prevent the bug, revert to the old behavior. I.e. read modem status only if we really have to -- for non-CLOCAL set serials. Non-CLOCAL works on this hardware OK, I tried. See? I don't. And document that shit.

2012-01-24iwlwifi: fix PCI-E transport "inta" raceJohannes Berg
When an interrupt comes in, we read the reason bits and collect them into "trans_pcie->inta". This happens with the spinlock held. However, there's a bug resetting this variable -- that happens after the spinlock has been released. This means that it is possible for interrupts to be missed if the reset happens after some other interrupt reasons were already added to the variable. I found this by code inspection, looking for a reason that we sometimes see random commands time out. It seems possible that this causes such behaviour, but I can't say for sure right now since it happens extremely infrequently on my test systems.

2012-01-24USB: cp210x: fix CP2104 baudrate usagePreston Fick
This fix changes the way baudrates are set on the CP210x devices from Silicon Labs. The CP2101/2/3 will respond to both a GET/SET_BAUDDIV command, and GET/SET_BAUDRATE command, while CP2104 and higher devices only respond to GET/SET_BAUDRATE. The current cp210x.ko driver in kernel version 3.2.0 only implements the GET/SET_BAUDDIV command. This patch implements the two new codes for the GET/SET_BAUDRATE commands. Then there is a change in the way that the baudrate is assigned or retrieved. This is done according to the CP210x USB specification in AN571. This document can be found here: http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/AN571.pdf&src=DocumentationWebPart Sections 5.3/5.4 describe the USB packets for the old baudrate method. Sections 5.5/5.6 describe the USB packets for the new method. This patch also implements the new request scheme, and eliminates the unnecessary baudrate calculations since it uses the "actual baudrate" method. This patch solves the problem reported for the CP2104 in bug 42586, and also keeps support for all other devices (CP2101/2/3). This patchfile is also attached to the bug report on bugzilla.kernel.org. This patch has been developed and test on the 3.2.0 mainline kernel version under Ubuntu 10.11.

2012-01-24USB: ftdi_sio: fix initial baud rateJohan Hovold
Fix regression introduced by commit b1ffb4c851f1 ("USB: Fix Corruption issue in USB ftdi driver ftdi_sio.c") which caused the termios settings to no longer be initialised at open. Consequently it was no longer possible to set the port to the default speed of 9600 baud without first changing to another baud rate and back again.

2012-01-24USB: ftdi_sio: fix TIOCSSERIAL baud_base handlingJohan Hovold
Return EINVAL if new baud_base does not match the current one. The baud_base is device specific and can not be changed. This restores the old (pre-2005) behaviour which was changed due to a misunderstanding regarding this fact (see https://lkml.org/lkml/2005/1/20/84).
