2012-02-18MFD: ucb1x00-core: add wakeup supportRussell King1-0/+4
Add genirq wakeup support for the ucb1x00 device. This allows an attached gpio_keys driver to wakeup the system. Touchscreen is also possible. When there are no wakeup sources, ask the platform to assert the reset signal to avoid any unexpected behaviour; this also puts the reset signal at the right level when power is removed from the device.

2012-02-18MFD: ucb1x00: convert to use genirqRussell King1-18/+4
Convert the ucb1x00 driver to use genirq's interrupt services, rather than its own private implementation. This allows a wider range of drivers to use the GPIO interrupts (such as the gpio_keys driver) without being aware of the UCB1x00's private IRQ system. This prevents the UCB1x00 core driver from being built as a module, so adjust the configuration to add that restriction.

2012-02-18MFD: ucb1x00-core: convert to use dev_pm_opsRussell King1-1/+1
Convert the ucb1x00-core driver to use dev_pm_ops rather than the legacy members in the mcp driver. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-18MFD: ucb1x00-core: use mutexes instead of semaphoresRussell King1-2/+2
Convert the ucb1x00 driver to use mutexes rather than the depreciated semaphores for exclusive access to the ADC. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

Provide a way to handle the software controlled ucb1x00 reset signal from the ucb1x00-core driver without having to code platform specifics into these drivers. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-18MFD: mcp/ucb1x00: separate ucb1x00 driver data from the MCP dataRussell King1-0/+3
Patch taken from 5dd7bf59e0 (ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp bus.) by Jochen Friedrich <jochen@scram.de>. This adds just the codec data part of the patch. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-01-20Revert "ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp bus."Russell King1-4/+1
This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7. Conflicts: scripts/mod/file2alias.c This change is wrong on many levels. First and foremost, it causes a regression. On boot on Assabet, which this patch gives a codec id of 'ucb1x00', it gives: ucb1x00 ID not found: 1005 0x1005 is a valid ID for the UCB1300 device. Secondly, this patch is way over the top in terms of complexity. The only device which has been seen to be connected with this MCP code is the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same driver. Adding a match table, requiring the codec string to match the hardware ID read out of the ID register, etc is completely over the top when we can just read the hardware ID register.

2009-11-27add gpiolib support to ucb1x00Thomas Kunze1-0/+3
The old access methods to the gpios will be removed when all users has been converted. (mainly ucb1x00-ts)
2009-11-27move drivers/mfd/*.h to include/linux/mfdThomas Kunze1-0/+255
So drivers like collie_battery driver can use those files easier.
