mfd: lpc_ich: Add support for iTCO v3

2014-03-19T09:00:02Z

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

2014-03-19T09:00:01Z

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. Signed-off-by: Peter Tyser Tested-by: Rajat Jain Reviewed-by: Guenter Roeck Signed-off-by: Lee Jones

mfd: lpc_ich: Only configure watchdog or GPIO when present

2014-03-19T09:00:00Z

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

2014-03-19T09:00:00Z

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. Signed-off-by: Peter Tyser Tested-by: Rajat Jain Reviewed-by: Guenter Roeck Signed-off-by: Lee Jones
