2009-12-13mfd: Cleanup pcf50633_probe error handlingLars-Peter Clausen1-17/+26
Currently the child devices were not freed if the irq could not be requested. This patch restructures the function, that in case of an error all previously allocated resources are freed.

2009-12-13mfd: Fix pcf50633-regulator drvdata usageLars-Peter Clausen1-1/+0
Currently the pcf50633-regulator driver data is set to the pcf50633 core structure, but the pcf50633-regulator remove handler assumes that it is set to the regulator device. This patch fixes the issue by accessing the pcf506533 core structure through its parent device and setting the driver data to the regulator device.

2009-12-13mfd: Use platform_device_add_data to set pcf50633 regulator platform dataLars-Peter Clausen1-1/+2
Platform devices allocated with platform_device_alloc should use platform_device_add_data to set the platform data, because kfree will be called on the platform_data when the device is released.

2009-12-13mfd: Fix memleak in pcf50633_client_dev_registerLars-Peter Clausen1-10/+0
Since platform_device_add_data copies the passed data, the allocated subdev_pdata is never freed. A simple fix would be to either free subdev_pdata or put it onto the stack. But since the pcf50633 child devices can rely on beeing children of the pcf50633 core device it's much more elegant to get access to pcf50633 core structure through that link. This allows to get completly rid of pcf5033_subdev_pdata.

2009-12-13mfd: Disable unnecessary pcf50633 shutdown on lowsysPaul Fertser1-0/+3
On gta02 hardware revision A5 it can actually bring the system down during normal operating conditions so we disable it. Signed-off-by: Paul Fertser <fercerpav@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2009-09-17mfd: use a dedicated workqueue for pcf50633 irq processingPaul Fertser1-1/+4
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.

2009-06-15mfd: remove driver_data direct access of struct deviceGreg Kroah-Hartman1-1/+1
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.
