2012-03-16mfd: Fix compilation error in tps65910.hVenu Byravarasu1-0/+2
'struct gpio_chip' is declared in include/asm-generic/gpio.h which is included by include/linux/gpio.h. However without including gpio.h, TPS65910.h declares a member of this type as part of 'struct tps65910' declaration. This causes compilation error, if gpio.h is not included before including tps65910.h, in source files.

2012-03-16device.h: audit and cleanup users in main include dirPaul Gortmaker6-6/+10
The <linux/device.h> header includes a lot of stuff, and it in turn gets a lot of use just for the basic "struct device" which appears so often. Clean up the users as follows: 1) For those headers only needing "struct device" as a pointer in fcn args, replace the include with exactly that. 2) For headers not really using anything from device.h, simply delete the include altogether. 3) For headers relying on getting device.h implicitly before being included themselves, now explicitly include device.h 4) For files in which doing #1 or #2 uncovers an implicit dependency on some other header, fix by explicitly adding the required header(s). Any C files that were implicitly relying on device.h to be present have already been dealt with in advance. Total removals from #1 and #2: 51. Total additions coming from #3: 9. Total other implicit dependencies from #4: 7. As of 3.3-rc1, there were 110, so a net removal of 42 gives about a 38% reduction in device.h presence in include/* Signed-off-by: Paul Gortmaker <[email protected]>

2012-03-06mfd : Copy the db8500 gic setting to the prcmuDaniel Lezcano2-0/+9
In the case we go to the retention mode, we decoupled the gic in order to have the A9 core to reach a stable WFI state. But we want the prcmu to wake up the A9 when the gic has a pending irq which is done by copying the gic settings to the to the prcmu.

This patch introduces a routine to check if there are some irqs pending on the gic. Usually this check is not relevant because it appears racy (an irq can arrive right after this check), but in the ux500 it makes sense because the prcmu decouples the gic from the A9 cores.

2012-03-06mfd: Add ab8500 version detection and enforcingLinus Walleij2-8/+58
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.

2012-03-06mfd: Add initial db8500 prcmu register access apiMattias Nilsson2-12/+154
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.

Add genirq wakeup support for the ucb1x00 device. This allows an attached gpio_keys driver to wakeup the system. Touchscreen is also possible.
