This adds the AB8500 core driver, which will be utilized by the follow-on drivers for different ABx500 variants. Sselect the driver from the DBX500_SOC, as this chip is powering and clocking that SoC.

MFD core now takes care of HWIRQ <-> VIRQ mapping, so the helper ab8500_irq_get_virq() is no longer used by ab8500 subordinate devices to obtain a Linux wide Virtual IRQ. The AB8500 IRQ controller still uses it internally though, so we'll just hide it from the rest of the world by making it static instead.

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: NPaul Gortmaker <paul.gortmaker@windriver.com>

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.

This moves all the header files related to the abx500 family into a common include directory below mfd. From now on we place any subchip header in that directory. Headers previously in e.g. <linux/mfd/ab8500/gpio.h> get prefixed and are now e.g. <linux/mfd/abx500/ab8500-gpio.h>. The top-level abstract interface remains in <linux/mfd/abx500.h>.

Add a new driver to support the AB8500 Power Management chip, replacing the current AB4500. The new driver replaces the old one, instead of an incremental modification, because this is a substantial overhaul including: - Split of the driver into -core and -spi portions, to allow another interface layer to be added - Addition of interrupt support - Switch to MFD core API for handling subdevices - Simplification of the APIs to remove a redundant block parameter - Rename of the APIs and macros from ab4500_* to ab8500_* - Rename of the files from ab4500* to ab8500* - Change of the driver name from ab4500 to ab8500 Acked-by: NLinus Walleij <linus.walleij@stericsson.com> Acked-by: NSrinidhi Kasagar <srinidhi.kasagar@stericsson.com> Signed-off-by: NRabin Vincent <rabin.vincent@stericsson.com> Signed-off-by: NSamuel Ortiz <sameo@linux.intel.com>
