2009-12-06backlight/mfd: Add pcf50633 backlight driverLars-Peter Clausen
This patch adds a backlight driver controling the pcf50633 led converter. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06MFD: pcf50633: Fix bitfield logic in interrupt handlerLars-Peter Clausen
As those constans are alread bitfields it's wrong Those constants are already bitfields.
2009-12-06mfd: pcf50633: Fix pcf50633-regulator drvdata usageLars-Peter Clausen
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. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06mfd: pcf50633: Use platform_device_add_data to set regulator platform dataLars-Peter Clausen
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. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06mfd: pcf50633: Cleanup pcf50633_probe error handlingLars-Peter Clausen
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. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>
2009-12-06mfd: pcf50633: Fix memleak in pcf50633_client_dev_registerLars-Peter Clausen
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. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de>

2009-12-06mfd: pcf50633 disable unnecessary shutdown on lowsysPaul Fertser
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>

2009-10-12mfd: Fix twl4030 boot with twl4030 usb transceiver enabledRoger Quadros
The usb regulator supplies (usb1v5, usb1v8 & usb3v1) must be available before adding the twl4030_usb child, else twl4030_usb_ldo_init() will always fail thus causing boot lock-up. This patch fixes boot on OMAP systems using the twl4030 usb transceiver.

2009-10-04mfd: AB3100 drop unused module parametersJean Delvare
The I2C_CLIENT_INSMOD_1 macro is only useful for i2c drivers which implement device detection. The ab3100 driver doesn't, so there is no point in calling it.

This makes it consistent with other buses (platform, i2c, vio, ...). I'm not sure why we use the prefixes, but there must be a reason. This was easy enough to do it, and I did it.

This adds support for the regulators found in the AB3100 Mixed-Signal IC. It further also defines platform data for the ST-Ericsson U300 platform and extends the AB3100 MFD driver so that platform/board data with regulation constraints and an init function can be passed down all the way from the board to the regulators.
