mfd: AB8500 system control driver This adds a pretty straight-forward system control driver for the AB8500. This driver will be used from the core platform, e.g the clock tree implementation in the machine code, and is by nature singleton. There are a few simple functions to read, write, set and clear registers so that the machine code can control its own foundation.

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>.

mfd: ab8500-sysctrl: Let sysctrl driver work without pdata A check for a valid plat->sysctrl was introduced in: 2377e52 mfd: ab8500-sysctrl: Error check clean up but the driver works just fine even without that initialization data, and enforcing it breaks existing platforms for no reason. This patch removes the check and let the driver go ahead with probe.

mfd: ab8500-sysctrl: Always enable pm_power_off handler AB8500 sysctrl driver implements a pm_power_off handler, but that is currently not registered until a specific platform data field is enabled.

mfd: AB8500 system control driver This adds a pretty straight-forward system control driver for the AB8500. This driver will be used from the core platform, e.g the clock tree implementation in the machine code, and is by nature singleton. There are a few simple functions to read, write, set and clear registers so that the machine code can control its own foundation.

Therefore move ab8500-sysctrl to arch_initcall level as well. The device is already added before the abx500 clk device, thus it will be probed before as well, which is exactly what we want.
