mfd: sta2x11-mfd: Add defines for some sta2x11 sctl registers

2012-11-20T11:21:16+00:00

These are required for the clock infrastructure code to properly configure
and control the sta2x11 PLLs.

mfd: sta2x11-mfd: Use defines for platform devices' names

2012-11-20T11:21:15+00:00

Since there are now many sta2x11-mfd platform devices, using defines
for their names looks like a better solution.

mfd: sta2x11-mfd: Add sta2x11_mfd_get_regs_data() function

2012-11-20T11:21:14+00:00

A couple of predefined clocks (mux and gated) need to be
initialized with the virtual address of the clock's controlling
register and the address of a spinlock used to protect against
races.

This function exports such data for all the mfd cells.

mfd: sta2x11-mfd: Add apb-soc regs driver and factor out common code

2012-11-20T11:21:14+00:00

A driver for the apb-soc registers is needed by the clock
infrastructure code to configure and control clocks on the sta2x11
chip.

Since some of the functions in sta2x11-mfd.c were almost identical
for the two existing platform devices, the following changes
have been performed to avoid further code duplication while
adding the apb-soc-regs driver:

* The sctl_regs and apbreg_regs fields in struct sta2x11_mfd
have been turned into just one array of pointers accessed by
device index.
* Platform probe methods have become one-liners invoking a
common probe with the device's index as second parameter.
* For loops have been inserted where the same operations
were performed for each of the two bars of a pci device.
* The apbreg_mask and sctl_mask functions were almost identical,
so they were turned into inline functions invoking a common
__sta2x11_mfd_mask() with the platform device's index as last
parameter. To do this, enum sta2x11_mfd_plat_dev has been declared in
sta2x11-mfd.h and more device types have been added to it.

mfd: Add driver for STA2X11 MFD block

This also introduces  to export a function that is in
the base sta2x11 support patches. The header will increase with other
prototypes and constants over time.
