* MFD: ucb1x00-ts: fix resume failureRussell King2012-01-221-27/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the ucb1x00 touchscreen is resumed while the touchscreen is being touched, the main thread stops responding. This occurs because two things happen: 1. When we suspended, we were woken up, and executed the loop. Finding that the touchscreen was not pressed, we prepare to schedule for a maximum timeout, before being stopped in try_to_freeze(). 2. an irq occurs, we disable the irq, and mark it as disabled, and wake the thread. This wake occurs while the thread is still within __refrigerator() 3. The thread is unfrozen, and __refrigerator() sets the threads state back to INTERRUPTIBLE. We then drop into schedule_timeout() with an infinite timeout and the IRQ disabled. This prevents any further screen touches activating the thread. Fix this by using kthread_freezable_should_stop() which handles the freezing issues for us outside of the hotspot where the task state matters. Include a flag to ignore the touchscreen until it is released to avoid sending unintended data to the application. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* MFD: ucb1x00-core: fix gpiolib direction_output handlingRussell King2012-01-211-6/+12
| | | | | | | | | | gpiolib drivers should first set the output data before setting the direction to avoid putting glitches on an output signal. As an additional bonus, we tweak the code to avoid unnecessary register writes to the output and direction registers if they have no need to be updated.

* MFD: ucb1x00-core: fix missing restore of io output data on resumeRussell King2012-01-211-0/+1
| | | | | | | | We were not restoring the UCB1x00 gpio output data on resume, resulting in incorrect GPIO output data after a resume. Add the missing register write. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* MFD: mcp-core: fix complaints from the genirq layerRussell King2012-01-201-6/+11
| | | | | | | | | | The genirq layer complains if an interrupt handler returns with interrupts enabled. The UCB1x00 handler does just this, because ucb1x00_enable() calls mcp_enable(), which uses spin_lock_irq() rather than spin_lock_irqsave(). Convert this, and the divisor setting functions to use spin_lock_irqsave(). Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* Revert "ARM: sa11x0: Implement autoloading of codec and codec pdata for mcp ↵Russell King2012-01-204-85/+16Star
| | | | | | | | | | | | | | | | | | | | | | | | | bus." 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.

| * mfd: Set twl4030-irq tertiary interrupts to be nested/threaded.NeilBrown2012-01-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | As tertiary interrupts are handled by handle_twl4030_sih calling handle_nested_irq, they do not need their own separate irq thread. So mark them as 'nested_thread' interrupts to avoid the extra thread creation. Tested on GTA04 Pheonux.

| * mfd: Fixed unconditional reset of the mc13xxx ADC reading enable bitsRobin van der Gracht2012-01-091-2/+2
| | | | | | | | | | | | | | | | | | | | When the ADC is being prepared for a single or multiple channel reading, the adc0 register is reconfigured without taking the lithium cell, charge current and battery current reading enable bits into account. Which results in clearing the bits. Signed-off-by: Robin van der Gracht <robin@protonic.nl> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| | | | | | | | | | | | | | | | This will allow us to move to a more idiomatic MFD model as drivers will be able to get the struct by looking at their parent device. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
