Mark Brown 7cccbdc844 mfd: Enable rbtree cache for wm831x devices
Most useful with the regulators where we're doing a lot of read/modify/write
updates in potentially performance critical paths.  Providing some defaults
would make this slightly better but this is a win right now.

Mark Brown 523d9cfbb2 mfd: Support software initiated shutdown of WM831x PMICs
In systems where there is no hardware signal from the processor to the
PMIC to initiate the final power off sequence we must initiate the
shutdown with a register write to the PMIC. Support such systems in the
driver. Since this may prevent a full shutdown of the system platform
data is used to enable the feature.

Avoid requesting the audpwron gpio in case of ES1.0
revision.
In the past we requested the gpio, but we did not
free it up, since we made the check for the revision
later. This results later checks for gpio validity to
fail, leaving the gpio reserved (even after the driver
has been removed).

We assign to init_data->irq and init_data->irq_base long before we

they are needed.

Moving the assignments below these two potential exits means we
completely avoid doing them in these two (failure) cases.

Mark Brown 5608801baf mfd: Don't ask about the TPS65912 core driver in Kconfig
The user has to select the I2C and SPI drivers individually and they select
the core driver for the device so there's no point in presenting the user
with an option for the core driver.

Dimitris Papastamos 08256712a2 mfd: Fix off by one in WM831x IRQ code
The GPIO IRQs aren't the first IRQs defined, we need to subtract the base
for the GPIOs as well to use them for array indexes.

Mark Brown ec2328c30b mfd: Implement tps65910 IRQ cleanup
The tps65910_irq_exit() cleanup function was generating a warning from
sparse due to the lack of a prototype. This wasn't causing GCC warnings
as the driver wasn't cleaning up its IRQs on exit at all so there was no
use of an unprototyped function.

Peter Huewe 8504d63804 mfd: Use kstrtoul_from_user in ab8500
This patch replaces the code for getting an unsigned long from a
userspace buffer by a simple call to kstroul_from_user.
This makes it easier to read and less error prone.
