* staging:iio:core add in kernel interface mapping and getting IIO channels.Jonathan Cameron2012-02-245-1/+447
| | | | | | | | | | | | | | | | | | | | | | | | Lifted from proposal for in kernel interface built on the out of staging branch. Two elements here: * Map as defined in "inkern.h" * Matching code to actually get the iio_dev and channel that we want from the global list of IIO devices. V4: Everything now built if iio is built (rather than being optional) Removal race condition prevented by using info pointer as a check of removal under a lock. V3: Drop the option of registering / getting channels using dev pointer. Stick to name only as suggested by Mark Brown (this has caused user confusion in the regulator framework.) V2: As per Greg KH suggestion, move over to registration by passing the tables into the provider drivers (how regulator does it). This does not prevent us using the original more flexible approach if at a later date there is a usecase that demands it.

* staging:iio:core set the iio_dev.info pointer to null on unregister under lock.Jonathan Cameron2012-02-242-0/+6
| | | | | | | | | | | This prevents use of provider callbacks after it has been unregistered. Note that all code using this that can be called from a consumer *must* check the pointer before using and hold the info_exist_lock throughout the usage of the callbacks in info.

* staging: tidspbridge: detect wdt3 feature at runtimeOmar Ramirez Luna2012-02-241-3/+7
| | | | | | | | | | | | | | | | | | In order to detect WDT feature on the dsp code, we need to find the symbol used to enable it inside the baseimage. This should fix the warning comming from L3 driver: WARNING: at arch/arm/mach-omap2/omap_l3_smx.c:161 omap3_l3_app_irq... In-band Error seen by IVA_SS at address 0 ...

| | | | | | | | | | | | | In order to detect it at runtime, we need the code handling wdt clock available at runtime to decide whether to enable or disable based on the baseimage symbols. Default timeout has been set to 5 seconds. Downside is that we will lose the option to set a custom timeout for overflow, but than can be added (if needed) as part of debugfs.

We had just set that memory to zeroes earlier and now we're writing over it with 0xff because we're writing past the end of the struct. I don't know if this actually causes a problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RAMster implements peer-to-peer transcendent memory, allowing a "cluster" of kernels to dynamically pool their RAM. This patch incorporates changes transforming zcache to work with a remote store. In tmem.[ch], new "repatriate" (provoke async get) and "localify" (handle incoming data resulting from an async get) routines combine with a handful of changes to existing pamops interfaces allow the generic tmem code to support asynchronous operations. Also, a new tmem_xhandle struct groups together key information that must be passed to remote tmem stores. Zcache-main.c is augmented with a large amount of ramster-specific code to handle remote operations and "foreign" pages on both ends of the "remotify" protocol. New "foreign" pools are auto-created on demand. A "selfshrinker" thread periodically repatriates remote persistent pages when local memory conditions allow. For certain operations, a queue is necessary to guarantee strict ordering as out-of-order puts/flushes can cause strange race conditions. Pampd pointers now either point to local memory OR describe a remote page; to allow the same 64-bits to describe either, the LSB is used to differentiate. Some acrobatics must be performed to ensure local memory is available to handle a remote persistent get, or deal with the data directly anyway if the malloc failed. Lots of ramster-specific statistics are available via sysfs. Note: Some debug ifdefs left in for now.

This patch copies files from drivers/staging/zcache. RAMster compresses pages locally before transmitting them to another node, so we can leverage the zcache and tmem code directly. Note: there are no ramster-specific changes yet to these files. (Why copy? The ramster tmem.c/tmem.h changes are definitely shareable between zcache and ramster; the eventual destination for tmem.c is the linux lib directory. Ramster changes to zcache are more substantial and zcache is currently undergoing some significant unrelated changes (including a new allocator and breaking zcache-main.c into smaller files), so it seemed best to branch temporarily and merge later.)
