mfd: lpc_sch: Enable WDT for Intel Quark X1000

2015-01-22T15:55:56+00:00

Quark X1000 uses ie6xx_wdt driver for WDT. To enable WDT, we declare WDT IO
resource size for Quark X1000.

mfd: lpc_sch: Don't call mfd_remove_devices()

2014-11-25T16:18:52+00:00

MFD core already cares about failing registration. It will remove successfully
registered devices in case of error. Thus, no need to repeatedly call
mfd_remove_devices().

mfd: lpc_sch: Remove FSF address

2014-09-26T07:15:59+00:00

This patch removes FSF address because it can be changed. While here, update
the copyright lines by adding Intel Corp. to them.

There is no functional change.

mfd: lpc_sch: Add support for Intel Quark X1000

2014-09-26T07:15:58+00:00

Intel Quark X1000 SoC supports IRQ based GPIO. This patch will
enable MFD support for Quark X1000 and provide IRQ resources
to Quark X1000 GPIO device driver.

mfd: lpc_sch: Reduce duplicate code and improve manageability

2014-09-26T07:15:57+00:00

This patch refactors the driver to use helper functions instead of
copy'n'pasted pieces of code.

It also introduces an additional struct to hold a chipset info. The chipset
info will be used to store features that are supported by specific processor or
chipset. LPC_SCH supports SMBUS, GPIO and WDT features. As this code base might
expand further to support more processors, this implementation will help to
keep code base clean and manageable.

The patch is partially based on the work done by Chang Rebecca Swee Fun.

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.

mfd: Remove DEFINE_PCI_DEVICE_TABLE macro

2014-01-21T08:27:45+00:00

Don't use DEFINE_PCI_DEVICE_TABLE macro, because this macro
is not preferred.

mfd: lpc_sch: Ignore resource conflicts when adding mfd cells

2013-10-23T15:22:40+00:00

Currently probe of lpc_sch fails on Intel Poulsbo because of ACPI resource
conflicts. A solution is to  set the ignore_resource_conflicts flag in the mfd cells.

mfd: lpc_sch: Accomodate partial population of the MFD devices

2013-02-13T23:26:45+00:00

The current probe aborts if any of the 3 base address registers are
disabled. On a TunnelCreek system I am working on, this resulted in the
SMBIOS and GPIO devices being removed when it couldn't read the base
address for the watchdog timer.

This patch accommodates partial population of the lpc_sch_cells array and
only aborts if all the base address registers are disabled. A max size
array is allocated and the individual device cells are added to it after
their base addresses are successfully determined. This simplifies the
code a bit by removing the need for the separate tunnelcreek cells array
and combining some of the add/remove logic.

mfd: remove use of __devexit

CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.
