mfd: lpc_ich: Add support for iTCO v3

2014-03-19T09:00:02+00:00

Some newer Atom CPUs, eg Avoton and Bay Trail, use slightly different
register layouts for the iTCO than the current v1 and v2 iTCO.
Differences from previous iTCO versions include:
- The ACPI space is enabled in the "ACPI base address" register instead
  of the "ACPI control register"

- The "no reboot" functionality is set in the "Power Management
  Configuration" register instead of the "General Control and Status"
  (GCS) register or PCI configuration space.

- The "ACPI Control Register" is not present on v3.  The "Power
  Management Configuration Base Address" register resides at the same
  address is Avoton/Bay Trail.

To differentiate these newer chipsets create a new v3 iTCO version and
update the MFD driver to support them.

mfd: lpc_ich: Remove lpc_ich_cfg struct use

2014-03-19T09:00:01+00:00

Future chipsets will use different register layouts that don't map
cleanly to the lpc_ich_cfg fields.  Remove the lpc_ich_cfg struct and
add explicit fields to the higher level lpc_ich_priv structure.

This change should have no functional impact.

mfd: lpc_ich: Only configure watchdog or GPIO when present

2014-03-19T09:00:00+00:00

Some chipsets don't currently have GPIO support enabled.  For these
chipsets don't go through the process of initializing the GPIO region.

Make the same change for the watchdog initialization for chipsets which
may not enable the WDT in the future.

mfd: lpc_ich: Fix ACPI enable bitmask

2014-03-19T09:00:00+00:00

The original bitmask of 0x10 was incorrect and would result in a write
to a reserved read-only bit instead of enabling the ACPI I/O
region.  Update it to the proper value of 0x80.

mfd: Delete non-required instances of include

2014-03-19T08:58:07+00:00

None of these files are actually using any __init type directives
and hence don't need to include .  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
