* intel_mid: Keypad DriverHEADmasterZheng Ba2010-12-143-0/+789
| | | | | | | | | | | | | This patch adds the keypad support for the MID platform keypad interfaces. Changes from Alpha2: solved "CRITICAL" issues marked by Klocwork HSD sighting 3469242 (some tidying Alan Cox) Signed-off-by: Zheng Ba <zheng.ba@intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com>
* i2c_intel_mid: Fix slash in sysfs nameAlan Cox2010-12-141-1/+1
| | | | | | | | | | | | This gets caught by the new sanity check code. Instead of the slash use a different symbol. This was originally found by Major Lee who proposed a rather more complex patch which changed the name according to the chip type. On the basis that we are in a late -rc and making Linus grumpy isn't always a good idea (however fun) this is a simple alternative. Signed-off-by: Alan Cox <alan@linux.intel.com>
* x86,mrst: Intel Medfield over-current detection patchDurgadoss R2010-12-133-0/+648
| | | | | | | | | | | | This patch enables over current detection on the Intel Medfield Platform. This driver provides sysfs interfaces to configure current thresholds. When the current being drawn on the platform exceeds the configured threshold, an interrupt is generated. This interrupt can be used to bring the current consumption down by taking necessary hardware or software actions.

| | | | | | | | | | | | | | | | | | This patch addresses some remove issues in the pti_pci_remove() and _exit() routines in the pti driver that were uncovered in module load and unload stress testing: 1. a double kfree() issue between the _remove() and _exit() routine 2. pci_release_region() in _remove() that was not really releasing the region from the _probe() call, thereby causing a BUSY error on the next load of the driver module. 3. 2. uncovered a corner-case issue in which misc_register() wasn't called in _probe() before an error-cleanup routine was called which was causing an issue in the _exit() routine. 4. A couple unregister_driver() calls added to exit(). Signed-off-by: J Freyensee <james_p_freyensee@linux.intel.com> Signed-off-by: Alan Cox <alan@linux.intel.com>
