b080c78a4e regulator: ab8500: Update voltage handling for fixed voltage regulators
There are a few over-lapping methods for voltage selection operating
in the AB8500 regulator driver currently. This patch removes unused,
unnecessary variables from the regulator_info structures and provides
voltage tables for those regulators which have fixed voltages.

5689e83074 regulator: ab8500: Use regulator_list_voltage_linear for fixed voltage
Both ab8500_regulator_mode_ops and ab8500_regulator_ops do not have volt_table
setting, thus we can not use regulator_list_voltage_table for them.
However, they have min_uV setting with n_voltages = 1, so use
regulator_list_voltage_linear instead.

Also remove setting set_voltage_time_sel for ab8500_regulator_mode_ops.
It is used only for fixed voltage, so it does not need to implement
set_voltage_time_sel.

There is already before a register mask in the regulator driver
to allow some bits of a register to be initialized. The register
value is defined in the board configuration. This patch puts a

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac96: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").

In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).

I left that part of commit 2761a63945 just undone.

07b9e329f9 regulator: ab8500: Remove min_uV and max_uV from struct ab8500_regulator_info
The min_uV and max_uV are not really used in the code and misleading because
the min_uV and max_uV settings does not match the value in the voltage table.

For example, we have
static const unsigned int ldo_vaux3_voltages[] = {
        1200000,
        1500000,
        1800000,
        2100000,
        2500000,
        2750000,
        2790000,
        2910000,
};

With below min_uV/max_uV settings for AB8500_LDO_AUX3.
.min_uV                 = 1100000,
.max_uV                 = 3300000,

The min_uV/max_uV for AB8500_LDO_AUX3 seems copy-paste from AB8500_LDO_AUX2
and is wrong.

7e715b954a regulator: Change ab8500 match names to reflect Device Tree
The 'name' field in 'struct of_regulator_match' expects to match with
its corresponding regulator device node in the Device Tree. This patch
renames each of the regulators in the ab8500 regulator driver so this
is true.

3a8334b948 regulator: Enable the ab8500 for Device Tree
Here we setup the ab8500 regulator driver for DT. We first do
this in the normal way, by providing a match structure during
initialisation, but then we provide information so that
whilst probing we can use existing data structures to do DT
look-ups.

a7ac1d9e4e regulator: ab8500: Split up probe() into manageable pieces
ab8500's probe() function is becoming quite large, so in the lead
up to Device Tree enablement which will fork the thread of execution
this patch splits it into 3 main areas; basic error checking will
remain in probe(), but regulator register initialisation and regulator
registration have been moved to their own functions which will
be called in sequence by probe() and the DT equivalent.

c172708d38 regulator: core: Use a struct to pass in regulator runtime configuration
Rather than adding new arguments to regulator_register() every time we
want to add a new bit of dynamic information at runtime change the function
to take these via a struct. By doing this we avoid needing to do further
changes like the recent addition of device tree support which required each
regulator driver to be updated to take an additional parameter.

The regulator_desc which should (mostly) be static data is still passed
separately as most drivers are able to configure this statically at build
time.

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>.

2c043bcbf2 regulator: pass additional of_node to regulator_register()
With device tree support for regulators, its needed that the
regulator_dev->dev device has the right of_node attached.
To be able to do this add an additional parameter to the
regulator_register() api, wherein the dt-adapted driver can
then pass this additional info onto the regulator core.
