mfd: twl: Fix TWL6032 phy vbus detection
TWL6032 has a few charging registers prepended before the charging registers the TWL6030 has. To be able to use common register defines declare the additional registers as additional module. At the moment this affects the access to CHARGERUSB_CTRL1 in phy-twl6030-usb. Without this patch, it is accessing the wrong register on TWL6032. The consequence is that presence of Vbus is not reported.

i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.)
So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

mfd: twl4030: Make twl4030_exit_irq() return void
If twl4030_exit_irq() returns an error, the effect is that the caller (twl_remove()) forwards the error to the i2c core without unregistering its dummy slave devices. This only makes the i2c core emit another error message and then it still removes the device.
In this situation it doesn't make sense to abort the remove cleanup and not unregister the slave devices. So do that. Then return value is actually unused and twl4030_exit_irq() can better be changed to return no value at all.

This function returns 0 unconditionally, so there is no benefit in returning a value at all and make the caller do error checking.
Also the caller (twl_remove()) cannot do anything sensible with an error code. Passing it up the call stack isn't a good option because the i2c core ignores error codes (apart from emitting an error message).

This is often because twl_probe lacks a __init annotation or the annotation of unprotect_pm_master is wrong.

treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of:
devm_kzalloc(handle, a * b, gfp)
with: devm_kcalloc(handle, a * b, gfp)
as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant.
Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".
The Coccinelle script used for this was:

mfd: twl-core: Make it explicitly non-modular
The Kconfig currently controlling compilation of this code is:
drivers/mfd/Kconfig:config TWL4030_CORE drivers/mfd/Kconfig: bool "TI TWL4030/TWL5030/TWL6030/TPS659x0 Support"
...meaning that it currently is not being built as a module by anyone.
Lets remove what modular code that we can, so that when reading the driver there is less doubt that it is builtin-only. Note that we can't remove the twl_remove() itself ; it is still used by the probe unwind routine. So we leave it linked into the .remove as well, even though it will most likely never be called via that path from an unbind.
Since module_i2c_driver() uses the same init level priority as builtin_i2c_driver() the init ordering remains unchanged with this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

twl4030_charger: use runtime_pm to keep usb phy active while charging.
The twl4030 usb phy needs to be active while we are using the USB VBUS as a current source for charging. In particular, the usb3v1 regulator must be enabled and the PHY_PWR_PHYPWD bit must be set to keep the phy powered.
commit ab37813f4093a5f59cb8e083cde277289dc72ed3 twl4030_charger: Allow charger to control the regulator that feeds it
gave the charger control over the regulator, but didn't resolve the PHY_PWR_PHYPWD issue.
Now that both of these are controlled by runtime_pm in phy-twl4030-usb, we can simply take a runtime_pm reference to the USB phy whenever the charger wants to use it as a current source.
So this patch reverts the above commit, and adds the necessary runtime_pm calls.

mfd: twl-core: Fix idle mode signaling for omaps when booted with device tree
I noticed a regression where the omap sys_clkreq signal will never trigger for omap3 when booted with device tree while it triggers when booted in legacy mode. This means voltage scaling does not do anything when booted with device tree.
Turns out the reason is we fail to initialize the SmartReflex enable bit in twl4030 with the following error:
twl: not initialized
And that happens because we are wrongly tinkering with the twl4030 registers in arch/arm/mach-omap2/omap_twl.c before the driver is initialized. Looking at the the SmartReflex bit enable code in omap_twl.c, we need to always set it.
So let's fix the issue by always enabling the twl4030 SmartReflex bit in the drivers/mfd/twl-core.c probe, and drop the related code in omap_twl.c.
Note that we still have some twl4030 tinkering left in omap_twl.c for the twl6030 case, but that's a different patch.

mfd: twl-core: Fix accessibility of some twl4030 audio registers
There are some unused registers in twl4030 at I2C address 0x49 and function twl4030_49_nop_reg() is used to check accessibility of that registers. These registers are written in decimal format but the values are correct in hexadecimal format. (It can be checked few lines above the patched code - these registers are marked as unused there.)
As a consequence three registers of audio submodule are treated as inaccessible (preamplifier carkit right and both handsfree registers).
