Philipp Zabel 1b89040c3a mfd: asic3: remove SD/SDIO controller register definitions
Only the base addresses remain, as they are needed to set up
the IOMEM resources.

Philipp Zabel 6483c1b5e1 mfd: asic3: add asic3_set_register common operation
Used to configure single bits of the SDHWCTRL_SDCONF and EXTCF_RESET/SELECT
registers needed for DS1WM, MMC/SDIO and PCMCIA functionality.

Philipp Zabel 99cdb0c8c5 mfd: let asic3 use mem resource instead of bus_shift
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.

Philipp Zabel 279cac484e mfd: remove DS1WM register definitions from asic3.h
There is a dedicated ds1wm driver, no need to duplicate this
information here.

Philipp Zabel 4a67b528e0 mfd: add ASIC3_CONFIG_GPIO templates
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.

Samuel Ortiz 3b8139f8b1 mfd: Use uppercase only for asic3 macros and defines
Let's be consistent and use uppercase only, for both macro and defines.

Samuel Ortiz 3b26bf1722 mfd: New asic3 gpio configuration code
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.

Samuel Ortiz 1effe5bc6c mfd: asic3 children platform data removal
Platform devices should be dynamically allocated, and each supported
device should have its own platform data.
For now we just remove this buggy code.

Samuel Ortiz 6f2384c4bd mfd: asic3 gpiolib support
ASIC3 is, among other things, a GPIO extender. We should thus have it
supporting the current gpiolib API.

Samuel Ortiz fa9ff4b185 ASIC3 driver
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.
