The 'switch' sysfs attribute is used for
showing and setting the switch state of the device.
However, setting it from the userspace focibly is not appropriate.
And showing the state can be handled from
other places (e.g. external connector) in a unified manner.
This patch removes the sysfs attribute.
Plus, uevent messages for interrupts are also removed.
The initial max8997-muic driver is merged at:

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>.

Concurrent access to UART2/combo-interface by multiple protocol drivers such
as BT, FM and GPS caused issues during firmware download failure cases or
cases when the firmware download took longer than usual.
This was because of un-safe access to protos_registered & st_states.
Protecting this will also make the registration complete callback un-safe for
sleep.

Some devices need to know if the data is to be output or read, so add a
data direction into the eeprom structure to tell the driver whether the
data line should be driven.
The user in this case is the Micrel KS8851 which has a direction
control for the EEPROM data line and thus needs to know whether
to drive it (writing) or to tristate it for receiving.

The driver for the DigsyMTC display configuration EEPROMs device got
added by commit 469dded183 ("misc/eeprom: add eeprom access driver for
digsy_mtc board"). Its Kconfig symbol depends on PPC_MPC5200_GPIO. But
at the time that driver got added PPC_MPC5200_GPIO was already renamed
to GPIO_MPC5200, by commit 6eae1ace68 ("gpio: Move mpc5200 gpio driver
to drivers/gpio").
So make this driver depend on GPIO_MPC5200. And since GPIO_MPC5200
itself implies that GPIOLIB is set, that dependency can be dropped.

ISSUE:
Using ML7831, MAC address writing doesn't work well.
CAUSE:
ML7831 and EG20T have the same register map for MAC address access.
However, this driver processes the writing the same as ML7223.
This is not true.
This driver must process the writing the same as EG20T.
This patch fixes the issue.

Currently, external ROM access is enabled/disabled in probe()/remove().
So, when a buggy software access unanticipated memory area,
in case of enabling this ADE bit,
external ROM memory area can be broken.
This patch enables the ADE bit only accessing external ROM area.

The regulator API contains a range of features for stubbing itself out
when not in use and for transparently restricting the actual effect of
regulator API calls where they can't be supported on a particular system
so that drivers don't need to individually implement this. Simplify the
driver slightly by making use of this idiom.
The only in tree user is ecovec24 which does not use the regulator API.

>From my POV, it looks like the hardware is not working as expected
and returns a bogus data rate. The driver doesn't check the result
and directly uses it as some sort of divisor in some places:
msleep(lis3->pwron_delay / lis3lv02d_get_odr());
Under this circumstances, this could very well cause the
"divide by zero" exception from above.
For now, I fixed it the easiest and most obvious way:
Check if the result is sane and if it isn't use a sane default
instead. I went for "100" in the latter case, simply because
/sys/devices/platform/lis3lv02d/rate returns it on a successful
boot.

We will need this to avoid build failures pending a future implicit
module.h presence cleanup.

These files really need the full module.h header file present, but
were just getting it implicitly before. Fix it up in advance so we
avoid build failures once the cleanup commit is present.

Commit 2a7fade7e03 ("hwmon: lis3: Power on corrections") caused a
regression on HP laptops with 8bit chip. Writing CTRL2_BOOT_8B bit seems
clearing the BIOS setup, and no proper interrupt for DriveGuard will be
triggered any more.
Since the init code there is basically only for embedded devices, put a
pdata check so that the problematic initialization will be skipped for
hp_accel stuff.
