2010-03-07gpio: Fix sch_gpio warningSamuel Ortiz
We need to check for gpiochip_remove() errors. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2010-03-07mfd: Use completion interrupt for WM831x AUXADCMark Brown
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.

2010-03-07mfd: Use completion interrupt for WM835x AUXADCMark Brown
Use the completion interrupt generated by the device rather than polling for conversions to complete. As a backup we still check the state of the AUXADC if we don't get a completion, mostly for systems that don't have the WM8350 interrupt infrastructure hooked up.

2010-03-07mfd: Introduce remove_script function for twl4030Mike Turquette
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.

2010-03-07mfd/mmc: SDHI Kconfig updateMagnus Damm

2010-03-07gpiolib: Force wm831x GPIOs into GPIO mode when requestedMark Brown
This is the chip default but it's possible the bootloader or OTP will have been configured to a different mode (eg, to provide feedback during startup). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-03-07mfd: Add WM831x revision B supportMark Brown
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.

2010-03-07tmio_mmc: Balance cell enable()/disable() callsMagnus Damm
This patch adds cell->disable() calls to the tmio-mmc probe() error handling and the remove() function. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-03-07tmio_mmc: Remove const from platform data V3Magnus Damm
Remove const from the tmio-mmc platform data hclk V3. This change makes it possible to remove the type cast from the sh_mobile_sdhi driver which is using the clock framework to get the clock rate. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2010-03-07tmio_mmc: Use 100ms mmc_detect_change() delayMagnus Damm
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.

2010-03-07tmio_mmc: Keep card-detect interrupts enabledGuennadi Liakhovetski
On SuperH platforms the SDHI controller does not produce any command IRQs after a completed IO. This leads to card-detect interrupts staying disabled.

2010-03-07mfd: Disable TWL4030/5030 I2C1/I2C4 internal pull-upsMoiz Sonasath
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.

2010-03-07mfd: Remove leftover from discontinued TWL4030 battery patchChristoph Egger
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.

2010-03-07mfd: Use AB3100 MFD core IRQ for interrupt randomnessLinus Walleij
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.

2010-03-07mfd: Add HTCPLD driverCory Maccarrone
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.
