2012-11-16misc: apds9802als: Fix the logic checking timeout in als_wait_for_data_ready()Axel Lin
In the case of timeout waiting for data ready, the retry variable is -1. This also fixes a bug: current code returns -ETIMEDOUT if latest retry success ( which means retry is 0 when exiting the while loop ).

2012-11-16usb: dwc3: core: move dwc3_cache_hwparams before dwc3_alloc_event_buffersKishon Vijay Abraham I
commit 392142 moved event buffer allocation out of dwc3_core_init() but event buffer allocation uses the cached copy of hwparams to determine the number of event buffers and the caching is done in dwc3_core_init. So moved dwc3_cache_hwparams function before dwc3_alloc_event_buffers so that dwc3_alloc_event_buffers sees the correct number of event buffers.

Only we meet the following conditions, we can enable the DMA support for auart: (1) We enable the DMA support in the dts file, such as arch/arm/boot/dts/imx28.dtsi. (2) We enable the hardware flow control. (3) We use the mx28, not the mx23. Due to hardware bug(see errata: 2836), we can not add the DMA support to mx23.

2012-11-16serial: mxs-auart: distinguish the different SOCsHuang Shijie
The current mxs-auart driver is used for both mx23 and mx28. But in mx23, the DMA has a bug(see errata:2836). We can not add the DMA support in mx23, but we can add DMA support to auart in mx28. So in order to add the DMA support for the auart in mx28, we should distinguish the distinguish SOCs. This patch adds a new platform_device_id table and a inline function is_imx28_auart() to distinguish the mx23 and mx28.

Allows overriding default methods serial_in/serial_out. In such platform specific replacement it is possible to use other regshift, biased register offset, any other manipulation that is not covered with common default methods. Overriding default methods may be useful for platforms which got serial peripheral with registers represented in big endian. In this situation and assuming that 32 bit operations / alignment is required then it may be useful to swab words before/after accessing the serial registers.

2012-11-16Revert "ACPI / x86: Add quirk for "CheckPoint P-20-00" to not use bridge ↵Rafael J. Wysocki
_CRS_ info" This reverts commit 0a290ac4252c85205cb924ff7f6da10cfd20fb01 on the basis of the following comment from Bjorn Helgaas: Here's my reasoning: this is a CheckPoint product, and it looks like an appliance, not really a general-purpose machine. The issue has apparently been there from day one, and the kernel shipped on the machine complains noisily about the issue, but apparently nobody bothered to investigate it. This corruption will clearly break other ACPI-related things. We can sort of work around this one (though the workaround does prevent us from doing any PCI resource reassignment), but we have no idea what the other lurking ACPI issues are (and we have no assurance that *only* ACPI things are broken -- maybe the memory corruption affects other unknown things). It may take significant debugging effort to identify the next problem. The only report I've seen (this one) is apparently from a CheckPoint employee, so it's not clear that anybody else is trying to run upstream Linux on it. Being a CheckPoint employee, [...] is probably in a position to get the BIOS fixed. You might still be able to convince me, but it seems like the benefit to a quirk for this platform is small, and it does cost everybody else something in code size and complexity.

2012-11-15serial: sh-sci: fix possible race cases on SCSCR register accessesShinya Kuribayashi
In the previous commit, console write function (serial_console_write) is changed to disable SCI interrupts while printing console strings. This introduces possible race cases in the serial startup / shutdown functions on SMP systems. This patch fixes the sh-sci in the same way as commit 9ec1882df2 (tty: serial: imx: console write routing is unsafe on SMP, from Xinyu Chen <xinyu.chen@freescale.com>, 2012-08-27) did. There could be several consumers of the console, * the kernel printk * the init process using /dev/kmsg to call printk to show log * shell, which opens /dev/console and writes with sys_write() The shell goes into the normal UART open() and write() system calls, while the other two go into the console operations. The open() call invokes serial startup function (sci_startup), which will write to the SCSCR register (to enable or disable SCI interrupts) without any locking. This will conflict with the console serial function. Add spinlock protections in sci_startup() and sci_shutdown() properly.

2012-11-15serial: sh-sci: add locking to console write function to avoid SMP lockupShinya Kuribayashi
Symptom: When entering the suspend with Android logcat running, printk() call gets stuck and never returns. The issue can be observed at printk()s on nonboot CPUs when going to offline with their interrupts disabled, and never seen at boot CPU (core0 in our case). Details: serial_console_write() lacks of appropriate spinlock handling. In SMP systems, as long as sci_transmit_chars() is being processed at one CPU core, serial_console_write() can stuck at the other CPU core(s), when it tries to access to the same serial port _without_ a proper locking. serial_console_write() waits for the transmit FIFO getting empty, while sci_transmit_chars() writes data to the FIFO. In general, peripheral interrupts are routed to boot CPU (core0) by Linux ARM standard affinity settings. SCI(F) interrupts are handled by core0, so sci_transmit_chars() is processed on core0 as well. When logcat is running, it writes enormous log data to the kernel at every moment, forever. So core0 can repeatedly continue to process sci_transmit_chars() in its interrupt handler, which eventually makes the other CPU core(s) stuck at serial_console_write(). Looking at serial/8250.c, this is a known console write lockup issue with SMP kernels. Fix the sh-sci driver in the same way 8250.c does.

2012-11-15serial: sh-sci: fix common SCIFB regmap definitionTakashi Yoshii
About FIFO count, there are two variants of SCIFs which show a) TX count in upper, RX count in lower byte of FDR register b) TX count in TFDR register, RX count in RFDR register Common SCIFB regmap in current source code is defined as "a". At least 7372 and 73a0 HW manual say their SICFB are "b". This patch alters the definition to "b", considering the current one has come from a mistake. The reason is as follows. The flag SCIFB sh-sci driver means it has 256 byte FIFO. The count is from 0(empty) to 256(full), that makes 9-bit. Because FDR is 16-bit register, it can not hold two 9-bits. That's why, SCIFB can not be "a".

2012-11-15serial: sh-sci: console runtime PM support (revisit)Teppei Kamijou
The commit 1ba7622094 (serial: sh-sci: console Runtime PM support, from Magnus Damm <damm@opensource.se>, 2011-08-03), tried to support console runtime PM, but unfortunately it didn't work for us for some reason. We did not investigated further at that time, instead would like to propose a different approach. In Linux tty/serial world, to get console PM work properly, a serial client driver does not have to maintain .runtime_suspend()/..resume() calls itself, but can leave console power power management handling to the serial core driver. This patch moves the sh-sci driver in that direction. Notes: * There is room to optimize console runtime PM more aggressively by maintaining additional local runtime PM calls, but as a first step having .pm() operation would suffice. * We still have a couple of direct calls to sci_port_enable/..disable left in the driver. We have to live with them, because they're out of serial core's help.

2012-11-15cdc-acm: implement TIOCSSERIAL to avoid blocking close(2)Dan Williams
Some devices (ex Nokia C7) simply don't respond at all when data is sent to some of their USB interfaces. The data gets stuck in the TTYs queue and sits there until close(2), which them blocks because closing_wait defaults to 30 seconds (even though the fd is O_NONBLOCK). This is rarely desired. Implement the standard mechanism to adjust closing_wait and let applications handle it how they want to. See also 02303f73373aa1da19dbec510ec5a4e2576f9610 for usb_wwan.c.

2012-11-15drivers/uwb: remove depends on CONFIG_EXPERIMENTALKees Cook
The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

2012-11-15misc: hpilo: ignore auxiliary HP iLO BMC'sMark Rusk
This patch ignores auxiliary HP Lights-Out (iLO) management controllers. All HP iLO controllers that have had the PCI subsystem device ID set to 0x1979 by the BIOS are ignored. Also changes default number of channels to 16 and bumps the version of the module from 1.3 to 1.4.
