2009-09-17mfd: use a dedicated workqueue for pcf50633 irq processingPaul Fertser
Using the default kernel "events" workqueue causes problems with synchronous adc readings if initiated from some task on the same workqueue. I had a deadlock trying to use pcf50633_adc_sync_read from a power_supply class driver because the reading was initiated from the workqueue and it waited for the irq processing to complete (to get the result) and that was put on the same workqueue.

For MFDs running regulator cores, we really want them to be brought up early during boot. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Mike Rapoport <mike@compulab.co.il>
2009-06-15mfd: remove driver_data direct access of struct deviceGreg Kroah-Hartman
In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used. These functions have been around since the beginning, so are backwards compatible with all older kernel versions.

2009-01-11mfd: PCF50633 core driverBalaji Rao
This patch implements the core of the PCF50633 driver. This core driver has generic register read/write functions and does interrupt management for its sub devices.
