* mfd: asic3: remove SD/SDIO controller register definitionsPhilipp Zabel2009-06-171-216/+3
| | | | | | | | Only the base addresses remain, as they are needed to set up the IOMEM resources. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: add ASIC3 IRQ numbersPhilipp Zabel2009-06-171-0/+7
| | | | | | | IRQ number definitions for PWM, LED, SPI and OWM (ds1wm). Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: asic3: add asic3_set_register common operationPhilipp Zabel2009-06-171-5/+5
| | | | | | | | Used to configure single bits of the SDHWCTRL_SDCONF and EXTCF_RESET/SELECT registers needed for DS1WM, MMC/SDIO and PCMCIA functionality. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
* mfd: let asic3 use mem resource instead of bus_shiftPhilipp Zabel2008-07-201-3/+2
| | | | | | | | | | | | | The bus_shift parameter in platform_data is not needed as we can tell the driver with the IOMEM_RESOURCE whether the ASIC is located on a 16bit or 32bit memory bus. The htc-egpio driver uses a more descriptive bus_width parameter, but for drivers where the register map size fixed, we don't even need this.

* mfd: remove DS1WM register definitions from asic3.hPhilipp Zabel2008-07-201-35/+3
| | | | | | | | There is a dedicated ds1wm driver, no need to duplicate this information here. Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
* mfd: add ASIC3_CONFIG_GPIO templatesPhilipp Zabel2008-07-201-0/+29
| | | | | | | | | | As ASIC3 GPIO alternate function configuration is expected to be similar for several devices, it is convenient to define descriptive macros. This patch is inspired by the PXA MFP configuration, the alternate functions were observed on hx4700 and blueangel.

* mfd: Use uppercase only for asic3 macros and definesSamuel Ortiz2008-07-201-28/+28
| | | | | | | Let's be consistent and use uppercase only, for both macro and defines. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
* mfd: New asic3 gpio configuration codeSamuel Ortiz2008-07-201-10/+24
| | | | | | | | | The ASIC3 GPIO configuration code is a bit obscure and hardly readable. This patch changes it so that it is now more readable and understandable, by being more explicit. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
* mfd: asic3 children platform data removalSamuel Ortiz2008-07-201-3/+0
| | | | | | | | | Platform devices should be dynamically allocated, and each supported device should have its own platform data. For now we just remove this buggy code. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
* mfd: asic3 gpiolib supportSamuel Ortiz2008-07-201-13/+11
| | | | | | | | ASIC3 is, among other things, a GPIO extender. We should thus have it supporting the current gpiolib API. Signed-off-by: Samuel Ortiz <sameo@openedhand.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org>
* ASIC3 driverSamuel Ortiz2008-02-071-0/+497
This is a patch for the Compaq ASIC3 multi function chip, found in many PDAs (iPAQs, HTCs...). It is a simplified version of Paul Sokolovsky's first proposal [1]. With this code, it is basically a GPIO and IRQ expander. My plan is to add more features once this patch gets reviewed and accepted.
