2013-07-03drivers/w1/slaves/w1_ds2408.c: add magic sequence to disable P0 test modeJean-Francois Dagenais
Power-up timing The DS2408 is sensitive to the power-on slew rate and can inadvertently power up with a test mode feature enabled. When this occurs, the P0 port does not respond to the Channel Access Write command. For most reliable operation, it is recommended to disable the test mode after every power-on reset using the Disable Test Mode sequence shown below. The 64-bit ROM code must be transmitted in the same bit sequence as with the Match ROM command, i.e., least significant bit first. This precaution is recommended in parasite power mode (VCC pin connected to GND) as well as with VCC power.

2013-07-03nbd: correct disconnect behaviorPaul Clements
Currently, when a disconnect is requested by the user (via NBD_DISCONNECT ioctl) the return from NBD_DO_IT is undefined (it is usually one of several error codes). This means that nbd-client does not know if a manual disconnect was performed or whether a network error occurred. Because of this, nbd-client's persist mode (which tries to reconnect after error, but not after manual disconnect) does not always work correctly. This change fixes this by causing NBD_DO_IT to always return 0 if a user requests a disconnect. This means that nbd-client can correctly either persist the connection (if an error occurred) or disconnect (if the user requested it).

2013-07-03rapidio: change endpoint device name formatAlexandre Bounine
Change endpoint device name format to use a component tag value instead of device destination ID. RapidIO specification defines a component tag to be a unique identifier for devices in a network. RapidIO switches already use component tag as part of their device name and also use it for device identification when processing error management event notifications. Forming an endpoint's device name using its component tag instead of destination ID allows to keep sysfs device directories unchanged in case if a routing process dynamically changes endpoint's destination ID as a result of route optimization. This change should not affect any existing users because a valid device destination ID always should be obtained by reading "destid" attribute and not by parsing device name. This patch also removes switchid member from struct rio_switch because it simply duplicates the component tag and does not have other use than in device name generation.

2013-07-03rapidio: update enumerator registration mechanismAlexandre Bounine
Update enumeration/discovery method registration mechanism to allow loading enumeration/discovery methods before all mports are registered. Existing statically linked RapidIO subsystem expects that all available RapidIO mport devices are initialized and registered before the enumeration/discovery method is registered. Switching to loadable mport device drivers creates situation when mport device driver can be loaded after enumeration/discovery method is attached (e.g., loadable mport driver in a system with statically linked RapidIO core and enumerator). This also will happen in a system with hot-pluggable RapidIO controllers. To remove the dependency on the initialization/registration order this patch introduces enumeration/discovery registration mechanism that supports arbitrary registration order of mports and enumerator/discovery methods. The following registration rules are implemented: - only one enumeration/discovery method can be registered for given mport ID (including RIO_MPORT_ANY); - when new enumeration/discovery methods tries to attach to the registered mport device, method with matching mport ID will replace a default method previously registered for given mport (if any); - enumeration/discovery method with target ID=RIO_MPORT_ANY will be attached only to mports that do not have another enumerator attached to them; - when new mport device is registered with RapidIO subsystem, registration routine searches for the enumeration/discovery method with the best matching mport ID; Signed-off-by: Alexandre Bounine <alexandre.bounine@idt.com> Cc: Matt Porter <mporter@kernel.crashing.org> Cc: Li Yang <leoli@freescale.com> Cc: Kumar Gala <galak@kernel.crashing.org> Cc: Andre van Herk <andre.van.herk@Prodrive.nl> Cc: Micha Nelissen <micha.nelissen@Prodrive.nl> Cc: Stef van Os <stef.van.os@Prodrive.nl> Cc: Jean Delvare <jdelvare@suse.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-07-03rapidio/rionet: rework driver initialization and removalAlexandre Bounine
Rework probe/remove routines to prevent rionet driver from monopolizing target RapidIO devices. Fix conflict with modular RapidIO switch drivers. Using one of RapidIO messaging channels rionet driver provides a service layer common to all endpoint devices in a system's RapidIO network. These devices may also require their own specific device driver which will be blocked from attaching to the target device by rionet (or block rionet if loaded earlier). To avoid conflict with device-specific drivers, the rionet driver is reworked to be registered as a subsystem interface on the RapidIO bus. The reworked rio_remove_dev() and rionet_exit() routines also include handling of individual rionet peer device removal which was not supported before.

2013-07-03rapidio: convert switch drivers to modulesAlexandre Bounine
Rework RapidIO switch drivers to add an option to build them as loadable kernel modules. This patch removes RapidIO-specific vmlinux section and converts switch drivers to be compatible with LDM driver registration method. To simplify registration of device-specific callback routines this patch introduces rio_switch_ops data structure. The sw_sysfs() callback is removed from the list of device-specific operations because under the new structure its functions can be handled by switch driver's probe() and remove() routines. If a specific switch device driver is not loaded the RapidIO subsystem core will use default standard-based operations to configure a switch. Because the current implementation of RapidIO enumeration/discovery method relies on availability of device-specific operations for error management, switch device drivers must be loaded before the RapidIO enumeration/discovery starts. This patch also moves several common routines from enumeration/discovery module into the RapidIO core code to make switch-specific operations accessible to all components of RapidIO subsystem.

/dev/oldmem provides the interface for us to access the "old memory" in the dump-capture kernel. Unfortunately, no one actually uses this interface. And this interface could actually cause some real problems if used on ia64 where the cached/uncached accesses are mixed. See the discussion from the link: https://lkml.org/lkml/2013/4/12/386.

2013-07-03drivers/rtc/rtc-sirfsoc.c: add rtc drivers for CSR SiRFprimaII and SiRFatlasVIXianglong Du
On CSR SiRFprimaII/atlasVI, there is a programmable 16-bit divider (RTC_DIV) that divides the input 32.768KHz clock to the frequency that users need (E.g. 1 Hz). The divided real-time clock will be used to drive a 32-bit counter (RTC_COUNTER) that provides users with the actual time. In each cycle of the divided real-time clock, there is a Hertz interrupt generated to the RISC. Users can also configure an alarm (RTC_ALARM). When RTC_COUNTER matches the alarm, there will be an alarm interrupt generated to the RISC. The system RTC can generate an alarm wake-up signal to notify the power controller to wake up from power saving mode.

2013-07-03rtc: omap: restore back (hard-code) wakeup supportHebbar Gururaja
rtc-omap driver modules is used both by OMAP1/2, Davinci SoC platforms. However, rtc wake support on OMAP1 is broken. Hence the device_init_wakeup() was removed from rtc-omap driver and moved to platform board files that supported it (DA850/OMAP-L138). [1] However, recently [2] it was suggested that driver should always do a device_init_wakeup(dev, true). Platforms that don't want/need wakeup support can disable it from userspace via: echo disabled > /sys/devices/.../power/wakeup Also, with the new DT boot-up, board file doesn't exist and hence there is no way to have device wakeup support rtc. The fix for above issues, is to hard code device_init_wakeup() inside driver and let platforms that don't need this, handle it through the sysfs power entry.

Convert drivers/rtc/class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, rtc class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the rtc class.

2013-07-03drivers/rtc/rtc-cmos.c: work around bios clearing rtc controlDerek Basehore
The bios may clear the rtc control register when resuming the system. Since the cmos interrupt handler may now be run before the rtc_cmos is resumed, this can cause the interrupt handler to ignore an alarm since the alarm bit is not set in the rtc control register. To work around this, check if the rtc_cmos is suspended and use the stored value for the rtc control register.

2013-07-03drivers/rtc/rtc-twl.c: ensure IRQ is wakeup enabledKevin Hilman
Currently, the RTC IRQ is never wakeup-enabled so is not capable of bringing the system out of suspend. On OMAP platforms, we have gotten by without this because the TWL RTC is on an I2C-connected chip which is capable of waking up the OMAP via the IO ring when the OMAP is in low-power states. However, if the OMAP suspends without hitting the low-power states (and the IO ring is not enabled), RTC wakeups will not work because the IRQ is not wakeup enabled. To fix, ensure the RTC IRQ is wakeup enabled whenever the RTC alarm is set.
