Cleanup GPIO IRQ enable/disable handling by removing SoC-specific
Also split enable/disable IRQ into separate functions for better
readability and also facilitate potentially moving to generic irq_chip
in the future.

Add register offset fields to GPIO platform_data for registers.
This patch adds registers that control direction, input and output
data. Using these register offsets in the common driver allows
removal of #ifdefs and greatly improves readability.
Also create dedicated data out functions: one for banks with dedicated
set/clear registers, and another for banks with a single mask
register.

Basically, other S3C SoCs and S5PC100 use 'S3C_VA_USB_HSPHY'
commonly. It should be changed to 'S3C_VA_USB_HSPHY' for common
usage and others. Now happens build error on S5PC100.

Speaker amplifier is accidentally powered up in early TWL gpio setup. This
causes a few mA of needless battery current consumption. Without this patch
the amplifier can be shutdown only by having one active audio playback and
shutdown cycle to speaker output.

The V28_A domain in Nokia N900 that supplies VDD voltages to TLV320AIC34 and
TPA6130A2 should not be shutdown. This is because otherwise there will be
leak from VIO to VDD in TLV320AIC34 and this leak consumes more battery
current that is saved from keeping V28_A off. With this patch the battery
current consumption is approximately 1.5 mA lower.

introduced by: 96974a24
(omap: consolidate touch screen initialization among different boards)
ads7846 driver can use either gpio_pendown or get_pendown_state()
callback. In case of gpio_pendown, it requests the provided gpio_pendown
thus resulting in double requesting that gpio:
ads7846 spi1.0: failed to request pendown GPIO57
ads7846: probe of spi1.0 failed with error -16
Fix this by restricting the gpio request to the case of
get_pendown_state() callback is used.

changes iovmm to receive flags specified by user, however

This fixes IOVMF_DA_FIXED flags from being lost, and lets the user

platform_device_del
Platform_device_del should be called before platform_device_put, as
platform_device_put can delete the structure.
Additionally, improve the error handling code for the call to ioremap, so
that it calls platform_device_put.

Currently, both the WM8903 and TPS6586x chips attempt to register with
gpiolib using the same GPIO numbers. This causes the audio driver to
fail to initialize.
To solve this, add a define to board-harmony.h for the TPS6586x, and make
board-harmony-power.c use this define, instead of directly referencing
TEGRA_NR_GPIOS.
This fixes a regression introduced by commit
6f168f2fa60f87e85e0df25e87e2372f22f5eb7c.

These definitions are needed to let the runtime PM subsystem turn off
DMAC clocks, when it is suspended by the driver.

On sh7372 the card-detection pin of SDHI0 can also produce interrupts,
when configured as GPIO. Use this feature to power down SDHI0, when no
card is plugged in.
