mfd: Fix NULL pointer due to non-initialized ucb1x00-ts absinfo

2011-03-31T18:58:15+00:00

commit 9063f1f15eec35e5fd608879cef8be5728f2d12a upstream. Call input_set_abs_params instead of manually setting absbit only.

mfd: Supply IRQ base for WM832x devices

2011-02-06T19:03:49+00:00

commit bd7c72ed18d719c1fb0fdf6ff9042d8ab78fdf71 upstream. Without this the IRQ base will not be correctly configured for the subdevices. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz Signed-off-by: Greg Kroah-Hartman Signed-off-by: Andi Kleen

mfd: Support additional parent IDs for wm831x

2011-02-06T19:03:49+00:00

commit b93cef556162b0f33399bfe5f307c54f51554e09 upstream. Some newer device revisions add a second parent ID. Support this in the device validity checks done at startup. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz Signed-off-by: Greg Kroah-Hartman Signed-off-by: Andi Kleen

mfd: Ignore non-GPIO IRQs when setting wm831x IRQ types

2010-10-29T04:51:26+00:00

commit c9d66d3515bbb0ad8062721487de7ade02d2b936 upstream. The driver was originally tested with an additional patch which made this unneeded but that patch had issuges and got lost on the way to mainline, causing problems when the errors are reported.

i2c: Remove all i2c_set_clientdata(client, NULL) in drivers

2010-06-03T09:33:58+00:00

I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

mfd: Storage class for timberdale should be before const qualifier

2010-05-27T23:38:01+00:00

The C99 specification states in section 6.11.5: The placement of a storage-class specifier other than at the beginning of the declaration specifiers in a declaration is an obsolescent feature. Signed-off-by: Tobias Klauser Signed-off-by: Samuel Ortiz

mfd: Remove unneeded and dangerous clearing of clientdata

2010-05-27T23:38:01+00:00

Unlike real i2c-devices which get detached from the driver, dummy-devices get truly unregistered. So, there has never been a need to clear the clientdata because the device will go away anyhow. For the occasions fixed here, clearing clientdata was even dangerous as the structure was freed already. Signed-off-by: Wolfram Sang Acked-by: Jean Delvare Signed-off-by: Samuel Ortiz

mfd: New AB8500 driver

2010-05-27T23:38:00+00:00

Add a new driver to support the AB8500 Power Management chip, replacing the current AB4500. The new driver replaces the old one, instead of an incremental modification, because this is a substantial overhaul including: - Split of the driver into -core and -spi portions, to allow another interface layer to be added - Addition of interrupt support - Switch to MFD core API for handling subdevices - Simplification of the APIs to remove a redundant block parameter - Rename of the APIs and macros from ab4500_* to ab8500_* - Rename of the files from ab4500* to ab8500* - Change of the driver name from ab4500 to ab8500 Acked-by: Linus Walleij Acked-by: Srinidhi Kasagar Signed-off-by: Rabin Vincent Signed-off-by: Samuel Ortiz
