* mfd: Rename twl4030* driver files to enable re-useSantosh Shilimkar2009-12-1322-21/+21
| | | | | | | | | | | | | | | 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.

* mfd: Don't set mc13783 ADREFMODE for touch conversionsUwe Kleine-König2009-12-131-2/+2
| | | | | | | | | | | Setting ADREFMODE is utter nonsense, but that's hard to read out of the spec. Strange enough it's possible to read x and y values even when it's set. When unset you can get values not only for the axes, but also for contact resistance which allows the touch driver to report pressure values.

* mfd: Remove ezx-pcap defines for custom led gpio encodingAntonio Ospite2009-12-131-3/+0
| | | | | | | | | | | We used these, in a first version of leds-pcap driver, in order to encode gpio enabling and gpio inversion for a led inside the variable used for the gpio number. In the new leds-pcap driver we rely on gpio_is_valid() to derive if a led is gpio enabled and we have a dedicated flag to tell if the gpio value has to be inverted.

* mfd: Near complete mc13783 rewriteUwe Kleine-König2009-12-133-466/+617
| | | | | | | | | | | | | | | | | | | | | | | This fixes several things while still providing the old API: - simplify and fix locking - better error handling - don't ack all irqs making it impossible to detect a reset of the rtc - use a timeout variant to wait for completion of ADC conversion - provide platform-data to regulator subdevice (This allows making struct mc13783 opaque for other drivers after the regulator driver is updated to use its platform_data.) - expose all interrupts - use threaded irq After all users in mainline are converted to the new API, some things (e.g. mc13783-private.h) can go away.

* mfd: Remove build time warning for WM835x register default tablesMark Brown2009-12-131-8/+0
| | | | | | | | | | | | | | Systems using the WM835x need to choose which of the default register settings are required on the system. Currently there is a compile time warning as well as a runtime error intended to flag up to users that this is required but this also triggers for people building the driver in order to obtain build coverage. Remove the build warning, leaving only the runtime error, in order to reduce noise for people doing generic kernel work.

| | | | | | | | | | This works around issues with allmodconfig where it won't propagate the dependency from the WM831x core back to the I2C and MFD cores. When doing allmodconfig this causes WM831x to be omitted and ensures that in normal builds the dependencies get shaken out.

* mfd: Move WM831x to generic IRQMark Brown2009-12-134-137/+122
| | | | | | | | | | | Replace the wm831x-local IRQ infrastructure with genirq, allowing access to the diagnostic infrastructure of genirq and allowing us to implement interrupt support for the GPIOs. The switchover is done within the wm831x specific IRQ API, further patches will convert the individual drivers to use genirq directly.

* mfd: Mask and unmask wm8350 IRQs on request and freeMark Brown2009-12-135-41/+9
| | | | | | | | | | | | | | | | | | | | Bring the WM8350 IRQ API more in line with the generic IRQ API by masking and unmasking interrupts as they are requested and freed. This is mostly just a case of deleting the mask and unmask calls from the individual drivers. The RTC driver is changed to mask the periodic IRQ after requesting it rather than only unmasking the alarm IRQ. If the periodic IRQ fires in the period where it is reqested then there will be a spurious notification but there should be no serious consequences from this. The CODEC drive is changed to explicitly disable headphone jack detection prior to requesting the IRQs. This will avoid the IRQ firing with no jack set up.
