mfd: let asic3 use mem resource instead of bus_shift

2008-07-20T17:56:44+00:00

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.h

2008-07-20T17:56:24+00:00

There is a dedicated ds1wm driver, no need to duplicate this
information here.

mfd: add ASIC3_CONFIG_GPIO templates

2008-07-20T17:56:19+00:00

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 defines

2008-07-20T17:55:14+00:00

Let's be consistent and use uppercase only, for both macro and defines.

mfd: New asic3 gpio configuration code

2008-07-20T17:55:00+00:00

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.

mfd: asic3 children platform data removal

2008-07-20T17:54:51+00:00

Platform devices should be dynamically allocated, and each supported
device should have its own platform data.
For now we just remove this buggy code.

mfd: asic3 gpiolib support

2008-07-20T17:52:38+00:00

ASIC3 is, among other things, a GPIO extender. We should thus have it
supporting the current gpiolib API.

ASIC3 driver

2008-02-07T16:42:23+00:00

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.
