2012-02-19ARM: sa11x0: add assabet ucb1x00 platform dataRussell King1-0/+6
Add ucb1x00 platform data to enable GPIO support on the UCB1300 device. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-19MFD: ucb1x00-core: add wakeup supportRussell King2-0/+63
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.

2012-02-19MFD: ucb1x00: convert to use genirqRussell King4-179/+132
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.

2012-02-19MFD: mcp-sa11x0: complain if mcp clock is left enabledRussell King1-0/+7
Issue a warning if the mcp clock was left enabled by some driver when we're suspending or tearing down the core driver for the device. This is an aid for debugging missing disable calls. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-19MFD: ucb1x00-core: disable mcp clock when bus is not requiredRussell King1-4/+5
The ucb1x00-core was leaving the mcp clock enabled indefinitely after probe. This needlessly wastes power. Add the necessary disables to ensure that the clock remains off when we don't need it. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-19MFD: ucb1x00-core: add missing ucb1x00_enable()/ucb1x00_disable()Russell King1-1/+15
ucb1x00_enable() and ucb1x00_disable() are used for power saving on the SIB interface, allowing the host supplied clock to be disabled when not required. We require drivers which access the ucb1x00 to ensure that they have enabled the clock prior to accessing the device, and they should disable it once they're done. As we don't expect gpiolib users to be aware of this detail, we must make these calls in the gpiolib interfaces. Add them. Also add them to the resume method, which needs to re-establish the GPIO pin settings. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-19MFD: ucb1x00-core: scan drivers in same order they're registeredRussell King1-4/+4
Cosmetic patch to scan the list of drivers in the order that the drivers are registered, rather than the reverse order. This avoids surprises when drivers get probed in the reverse order, and input devices get registered in a different order due to bind/unbind than from boot.

2012-02-03MFD: mcp-sa11x0: use _noirq resume methodsRussell King1-1/+8

2012-02-03MFD: mcp-sa11x0: convert mcp-sa11x0 to use platform resourcesRussell King2-42/+104
Patch taken from af9081ae64 (ARM: sa1100: Refactor mcp-sa11x0 to use platform resources.) by Jochen Friedrich <jochen@scram.de>, and fixes applied. We can safely do this now that we have sanitized host removal; the original patch had use-after-free bugs in the removal code. Not only that, but there was no checking of the ioremap() return. The final change over Jochen's patch is that we wrap the base pointer selection inside the various register indexes, which reduces the possibility of the wrong register index being used.

2012-02-03MFD: mcp-sa11x0: add .owner initializerRussell King1-6/+4

2012-02-03MFD: mcp-sa11x0: move setup of PPC unit out of mcp-sa11x0.cRussell King9-9/+19
Patch taken from af9081ae64 (ARM: sa1100: Refactor mcp-sa11x0 to use platform resources.) by Jochen Friedrich <jochen@scram.de>, and consolidated to use a common function. Move the setup of the PPC unit out of mcp-sa11x0 into the core SA11x0 code, and call it from each platforms initialization file. This centralizes the setup of the PPC unit while not polluting the mcp-sa11x0 driver with these details.

2012-02-03MFD: mcp-sa11x0: remove DMA initializers and variablesRussell King6-17/+0
The dma_device_t variables are only ever written to by mcp-sa11x0 and never read. As the old SA11x0 DMA support will be removed, remove these so that it no longer depends on the old SA11x0 DMA definitions. Acked-by: Jochen Friedrich <jochen@scram.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-02-03MFD: mcp-core: sanitize host creation/removalRussell King3-10/+20
host_unregister() gives us no chance between removing the device and the mcp data structure being freed to access the data inbetween, which drivers may need to do if they need to iounmap() pointers in their private data structures. Therefore, re-jig the interfaces, which are now, on creation: mcp = mcp_host_alloc() if (mcp) { ret = mcp_host_add(mcp, data); if (!ret) mcp_host_free(mcp); } and on removal: mcp_host_del(mcp); ... access mcp ... mcp_host_free(mcp); The free does the final put_device() on the struct device as one would expect.

2012-01-23MFD: ucb1x00-ts: fix resume failureRussell King1-27/+5
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>
2012-01-21MFD: ucb1x00-core: fix gpiolib direction_output handlingRussell King1-6/+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. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-01-21MFD: ucb1x00-core: fix missing restore of io output data on resumeRussell King1-0/+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>
2012-01-21MFD: mcp-core: fix mcp_priv() to be more type safeRussell King1-1/+4
mcp_priv() does unexpected things when passed a void pointer. Make it a typed inline function, which ensures that it works correctly in these cases. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2012-01-20MFD: mcp-core: fix complaints from the genirq layerRussell King1-6/+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>

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.

2012-01-19tpm: fix (ACPI S3) suspend regressionStefan Berger2-0/+12
This patch fixes an (ACPI S3) suspend regression introduced in commit 68d6e6713fcb ("tpm: Introduce function to poll for result of self test") and occurring with an Infineon TPM and tpm_tis and tpm_infineon drivers active. The suspend problem occurred if the TPM was disabled and/or deactivated and therefore the TPM_PCRRead checking the result of the (asynchronous) self test returned an error code which then caused the tpm_tis driver to become inactive and this then seemed to have negatively influenced the suspend support by the tpm_infineon driver... Besides that the tpm_tis drive may stay active even if the TPM is disabled and/or deactivated. Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Tested-by: Rafael J.
