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. Signed-off-by: Ong Boon Leong Signed-off-by: Lee Jones

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. Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

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. Signed-off-by: Chang Rebecca Swee Fun Tested-by: Chang Rebecca Swee Fun Signed-off-by: Andy Shevchenko Signed-off-by: Lee Jones

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. Signed-off-by: Andy Shevchenko Tested-by: Chang Rebecca Swee Fun Signed-off-by: Lee Jones

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. Signed-off-by: Paul Gortmaker Signed-off-by: Lee Jones

mfd: Remove DEFINE_PCI_DEVICE_TABLE macro

Don't use DEFINE_PCI_DEVICE_TABLE macro, because this macro is not preferred. Signed-off-by: Jingoo Han Signed-off-by: Lee Jones

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. Tested-by: Andreas Werner Signed-off-by: Johannes Thumshirn Signed-off-by: Lee Jones

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.
