938e05bf13 regulator: Fix an s5m8767 build failure
Due to a merge conflict we are getting this:

drivers/regulator/s5m8767.c: In function ‘s5m8767_pmic_probe’:
drivers/regulator/s5m8767.c:575:2: error: implicit declaration of function
‘s5m_reg_write’ [-Werror=implicit-function-declaration]

This is fixed by fully converting this driver to the new s5m API.

3e701cdfe6 MFD bits for the 3.6 merge window.
We have support for a few new drivers:
 - Samsung s2mps11
 - Wolfson Microelectronics wm5102 and wm5110
 - Marvell 88PM800 and 88PM805
 - TI twl6041
 
 We also have our regular driver improvements:
 - Device tree and IRQ domain support for STE AB8500
 - Regmap and devm_* API conversion for TI tps6586x
 - Device tree support for Samsung max77686
 - devm_* API conversion for STE AB3100
 
 Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910,
 tps65090, da9052 and twl-core.

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.

bdc0077af5 SCSI misc on 20120724
The most important feature of this patch set is the new async infrastructure
 that makes sure async_synchronize_full() synchronizes all domains and allows
 us to remove all the hacks (like having scsi_complete_async_scans() in the
 device base code) and means that the async infrastructure will "just work" in
 future. The rest is assorted driver updates (aacraid, bnx2fc, virto-scsi,
 megaraid, bfa, lpfc, qla2xxx, qla4xxx) plus a lot of infrastructure work in
 sas and FC.

2955b47d2c [SCSI] async: introduce 'async_domain' type
This is in preparation for teaching async_synchronize_full() to sync all
pending async work, and not just on the async_running domain.  This
conversion is functionally equivalent, just embedding the existing list
in a new async_domain type.

The .registered attribute is used in a later patch to distinguish
between domains that want to be flushed by async_synchronize_full()
versus those that only expect async_synchronize_{full|cookie}_domain to
be used for flushing.

8a165df7a9 regulator: palmas: Fix calcuating selector in palmas_map_voltage_smps
The logic of calculating selector in palmas_map_voltage_smps() does not match
the logic to list voltage in palmas_list_voltage_smps().

We use below equation to calculate voltage when selector > 0:
        voltage = (0.49V + (selector * 0.01V)) * RANGE
RANGE is either x1 or x2

So we need to take into account with the multiplier set in VSEL register when
calculating selector in palmas_map_voltage_smps()

a3cb80f43a regulator: twl: Fix the formula to calculate vsel and voltage for twl6030ldo
In twl6030ldo_set_voltage, current code use below formula to calculate vsel:
        vsel = (min_uV/1000 - 1000)/100 + 1;
This is worng because when min_uV is 1000000 uV, vsel is 1.
It should be 0 in this case.
Fix it by change the equation to: (This equation is common for linear mapping)
        vsel = DIV_ROUND_UP(min_uV - rdev->desc->min_uV, rdev->desc->uV_step);

In twl6030ldo_get_voltage, current code use below formula to calculate voltage:
        mV = 1000mv + 100mv * (vsel - 1)
This is worng because when vsel is 0, mV is 900mV. Note the min_uV is 1000mV.
Fix it by change the equation to: (This equation is common for linear mapping)
        return rdev->desc->min_uV + vsel * rdev->desc->uV_step;

5febb3c9d5 regulator: s5m8767: Properly handle gpio_request failure
Convert to devm_gpio_request to save a few error handling code.

This patch properly handle the gpio_request failure, we should return error
when gpio_request fails rather than just show warning.

I think one of the reason we got -EBUSY is because current code does not free
gpios in s5m8767_pmic_remove(). So it got -EBUSY when reload the module.

Yest another reason is in current code if gpio_request() returns error,
the rest of the code still calls gpio_direction_output to config buck_gpios

232b250475 regulator: s2mps11: Fix wrong setting for config.dev
Currently s2mps11->iodev, s2mps11->dev and config.dev point to NULL.
This patch fixes the settings for config.dev.
Current code does not need the *dev and *iodev of struct s2mps11_info,
so remove them.

faa95fde43 regulator: tps65910: Remvoe tps65910_reg_[read|modify_bits|read_locked|write_locked] functions
The tps65910 mfd driver has been converted to regmap APIs.
This patch adds tps65910_reg_update_bits() in include/linux/mfd/tps65910.h.
Thus we can use tps65910_reg_read/tps65910_reg_write/tps65910_reg_update_bits
directly and remove tps65910_reg_[read|modify_bits|read_locked|write_locked]
functions. With this change, we can also remove the mutex in struct tps65910_reg.

7be531883a regulator: tps65910: correct init value of n_voltages
Recent change in the core driver to get the maximum voltage
is based on the (n_voltages -1) steps of voltage.
For the tps65910, the (n_voltages -1)th step voltage is
calculated based on the callback function list_voltage.
This function direct maps the datasheet and adjust the
first few steps for initial voltage as per datasheet,
and hence initialize the n_voltages based on datasheet.

With changes introduced by commit 222cc7b (regulator: core: Allow
multiple requests of a single supply mapping) on create_regulator,
regulator_put needs a corresponding update on sysfs entry removing.

Also regulator->dev still needs to get assigned in create_regulator,
otherwise, sysfs_remove_link call in regulator_put will get bypassed.

9c6a74c5e0 regulator: ad5398: Fix min/max current limit boundary checking
It is ok to request current limit with min_uA < chip->min_uA and
max_uA > chip->max_uA.

We need to set min_uA = chip->min_uA if (min_uA < chip->min_uA),
this ensures the equation to calcuate selator does not return negative number.

Also set max_uA = chip->max_uA if (max_uA > chip->max_uA), as suggested by
Sonic.
