New function twl4030_remove_script(u8 flags) takes a script type as
defined in twl.h and prevents any script already loaded in that position
from running. This is accomplished by programming SEQ_ADD_* to 0x3f,
the END_OF_SCRIPT value, where SEQ_ADD_* is determined by flags.
(Future) users of this function include OMAP board files for machines
facing a race condition between sleep and warm reset.

This patch disables TWL4030/5030 I2C1 adn I2C4(SR) internal pull-up, to
use only the external HW resistor >=470 Ohm for the assured
functionality in HS mode.
While testing the I2C in High Speed mode, it was discovered that
without a proper pull-up resistor, there is data corruption during
multi-byte transfer. RTC(time_set) test case was used for testing.
From the analysis done, it was concluded that ideally we need a
pull-up of 1.6k Ohm(recomended) or atleast 470 Ohm or greater for
assured performance in HS mode.

The TWL4030_BCI_BATTERY config option originates from a patch to the
omap git tree. However inclusion in linux was seemingly rejected and
the functionality nears inclusion under a different name so this
removes the bits of the old version that made it into the mainline
kernel again.

In order to have TWL6030 CODEC driver as a platform driver, codec data
should be passed through twl_platform_data structure.
For twl6030 audio codec, the following data may be passed:
- audpwron_gpio: gpio line used to power-up/down the codec. A low-to-high
transition powers codec up. Setting audpwron_gpio to a negative value
means that codec will use manual power sequence instead of automatic
sequence
- naudint_irq: irq line for audio interrupt. twl6030 drives NAUDINT line
to low when an interrupt (codec ready, plug insertion/removal, etc) is
detected
However, codec driver can operate if any or none of them are passed.

This patch adds initial support for creating twl6030 PMIC
specific voltage regulators in the twl mfd driver.
Board specific regulator configurations will have to be passed from
respective board files.

This patch updates the regulator driver to add support
for TWL6030 PMIC specific LDO regulators.
SMPS resources are not yet supported for TWL6030 and
also .set_mode and .get_status for LDO's are yet to
be implemented for TWL6030.

This patch adds support for phoenix interrupt framework. New iInterrupt
status register A, B, C are introduced in Phoenix and are cleared on write.
Due to the differences in interrupt handling with respect to TWL4030,
twl6030-irq.c is created for TWL6030 PMIC

The upcoming TWL6030 is companion chip for OMAP4 like the current TWL4030
for OMAP3. The common modules like RTC, Regulator creates opportunity
to re-use the most of the code from twl4030.
This patch renames few common drivers twl4030* files to twl* to enable
the code re-use.
