LPC_SCH is selected by GPI_SCH and I2C_ISCH, even when PCI is not
enabled, but LPC_SCH depends on PCI, so make GPI_SCH and I2C_ISCH
also depend on PCI.
Those 2 selects also need to select what LPC_SCH selects,
since kconfig does not follow selects.

Use the completion interrupt generated by the device rather than
polling for conversions to complete. As a backup we still check
the status of the AUXADC if we don't get a completion, mostly for
systems that don't have the WM831x interrupt infrastructure hooked
up.
Also reduce the timeout for completion of conversions to 5ms from
the previous 10ms, the lower timeout should be sufficient.

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.

Revision B of the WM831x devices changes the sense of the tristate
bit for GPIO configuration, inverting it to become an enable instead.
Take account of this in the gpiolib driver.
A current sink regulation status bit has also been added in revision B,
add a flag indicating if it's present but don't use it yet.
This revision also adds an interrupt on key up for the ON pin event
which the existing code is able to take advantage of.

This patch changes the tmio_mmc driver to wait 100ms
before checking the card detect status. This type of
delay is quite common among mmc drivers, it seems that
most hardware platforms need to give the hardware some
time to settle before checking card availabilty.
Hotplug is half-broken without this patch on the sh7724
Ecovec board. Hot insertion seems ok but eject is never
detected without this patch.

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.

This reintroduces the entropy sampling of the AB3100 IRQ as the
IRQF_SAMPLE_RANDOM is going out according to the feature removal
schedule. I'm trying to do this the right way then, so CC:ing some
random people for a quick review. We add entropy for interrupt
events in the AB3100 which are truly random in nature, like
external cables being connected, voltages on batteries dropping
below certain ranges, ADC triggers or overheating.

This change introduces a driver for the HTC PLD chip found
on some smartphones, such as the HTC Wizard and HTC Herald.
It works through the I2C bus and acts as a GPIO extender.
Specifically:
* it can have several sub-devices, each with its own I2C
address
* Each sub-device provides 8 output and 8 input pins
* The chip attaches to one GPIO to signal when any of the
input GPIOs change -- at which point all chips must be
scanned for changes
This driver implements the GPIOs throught the kernel's
GPIO and IRQ framework. This allows any GPIO-servicing
drivers to operate on htcpld pins, such as the gpio-keys
and gpio-leds drivers.
