| * mfd: Fix ACPI conflict checkJean Delvare2012-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | The code is currently always checking the first resource of every device only (several times.) This has been broken since the ACPI check was added in February 2010 in commit 91fedede0338eb6203cdd618d8ece873fdb7c22c. Fix the check to run on each resource individually, once.

| * mfd: Add ab8500 version detection and enforcingLinus Walleij2012-03-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are currently four different versions of the AB8500 around: AB8500, AB8505, AB9540 and AB8540. Unfortunately: - Some of the chips (AB8500, AB8505, AB9540) cannot read the AB8500_REV_REG register but return errors - Some of them have the same ID value in the hardware register AB8500_REV_REV, for example the first versions of AB8505 and AB9540 have 0xFF in this register - just like the AB8500. So we need to be able to enforce a certain version from the platform. We do this by using the id of the platform device that provides the read/write functions.

| | | | | | | | | | | | | | | | | | | | | | | | The gpio_to_irq() macro is now defined as __gpio_to_irq() instead of IRQ_GPIO(). The __gpio_to_irq() function returns -ENXIO if the referenced gpio_chip structure does not define a to_irq() member. This is true of the asic3 gpio_chip structure, and thus calls to gpio_to_irq() now fail (for example from the gpio-vbus module).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an initial PRCMU register access API, which for now should only be used for a very limited set of registers. The idea about this API is that we split the PRCMU driver in one part that deals with interaction with the PRCMU firmware and one part that simply provide write accessors in the PRCMU register range. The latter are just a collection of registers exposed in the PRCMU register range for various purposes and not related to the PRCMU firmware. Currently we support some limited GPIO, SPI and UART settings through this API.

| * | watchdog: coh901327_wdt.c: fix timeoutWim Van Sebroeck2012-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the timeout value properly so that we don't get faulty values for the WDIOC_GETTIMEOUT iotcl. 'margin' should be an unsigned int. Also add a check to see if margin is a valid parameter after it is loaded as a module.

| * | watchdog: coh901327: convert to use watchdog coreLinus Walleij2012-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts the COH901327 watchdog to use the watchdog core. I followed Wolframs document, looked at some other drivers and tested it on the U300.

| * | watchdog: Add support for WDIOC_GETTIMELEFT IOCTL in watchdog coreViresh Kumar2012-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for WDIOC_GETTIMELEFT IOCTL in watchdog core. So, there is another function pointer added to struct watchdog_ops, which can be passed by drivers to support this IOCTL. Related documentation is updated too.

| * | watchdog: ep93xx_wdt: Fix timeout after conversion to watchdog coreMika Westerberg2012-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the conversion of this driver to the watchdog core, I noticed that we miss setting the initial timeout of the wdt device. This results in a failure of the WDIOC_GETTIMEOUT ioctl call.
