2014-05-08mmc: rtsx: Revert "mmc: rtsx: add support for pre_req and post_req"Micky Ching1-91/+41
This reverts commit c42deffd5b53c9e583d83c7964854ede2f12410d. commit <mmc: rtsx: add support for pre_req and post_req> did use mutex_unlock() in tasklet, but mutex_unlock() can't be used in tasklet(atomic context). The driver needs to use mutex to avoid concurrency, so we can't use tasklet here, the patch need to be removed. The spinlock host->lock and pcr->lock may deadlock, one way to solve the deadlock is remove host->lock in sd_isr_done_transfer(), but if using workqueue the we can avoid using the spinlock and also avoid the problem.

The plan is still to move the devicetree files out of the kernel tree and reduce the amount of churn going on here, but we keep finding reasons to delay doing that. Changes are really all over the place, with little sticking out particularly. We have contributions from a total of 116 people in this branch. Unfortunately, the size of this branch also causes a significant number of conflicts at the moment, typically when subsystem maintainers merge patches that change the driver at the same time as the dts files.

2014-03-20mfd: kempld-core: Fix potential hang-up during bootGuenter Roeck1-2/+5
On PXT and COMe-cPC2 boards it is observed that the hardware mutex is acquired but not being released during initialization. This can result in a hang-up during boot if the driver is built into the kernel. Releasing the mutex twice if it was acquired fixes the problem. Subsequent request/release cycles work as expected, so the fix is only needed during initialization.

regmap_add_irq_chip fail Fixes: 4aab3fadad32 ("mfd: tps65910: Move interrupt implementation code to mfd file") tps65910_irq_init() sets 'tps65910->chip_irq' before calling regmap_add_irq_chip(). If the regmap_add_irq_chip() call fails in memory allocation of regmap_irq_chip_data members then: 1. The 'tps65910->chip_irq' will still hold some value 2. 'tps65910->irq_data' will be pointing to already freed memory (because regmap_add_irq_chip() will free it on error) This results in invalid memory access during driver remove because the tps65910_irq_exit() tests whether 'tps65910->chip_irq' is not zero.

2014-03-19mfd: lpc_ich: Add support for iTCO v3Peter Tyser1-14/+67
Some newer Atom CPUs, eg Avoton and Bay Trail, use slightly different register layouts for the iTCO than the current v1 and v2 iTCO. Differences from previous iTCO versions include: - The ACPI space is enabled in the "ACPI base address" register instead of the "ACPI control register" - The "no reboot" functionality is set in the "Power Management Configuration" register instead of the "General Control and Status" (GCS) register or PCI configuration space. - The "ACPI Control Register" is not present on v3. The "Power Management Configuration Base Address" register resides at the same address is Avoton/Bay Trail.

Use a regmap so that the pm8xxx read/write APIs can be removed once all consumer drivers are converted. Reviewed-by: Mark Brown <broonie@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

Convert this driver to use irqdomains so that the PMIC's child devices can be converted to devicetree. Acked-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2014-03-19mfd: pm8921: Update for genirq changesStephen Boyd2-3/+5
Since this code has been marked broken for some time a few genirq tree wide changes weren't made. set_irq_wake() was renamed to irq_set_irq_wake() in commit a0cd9ca2b (genirq: Namespace cleanup, 2011-02-10) and commit 10a8c383 (irq: introduce entry and exit functions for chained handlers) introduced the chained irq functions but this driver wasn't updated to use them. Fix these problems and remove the BROKEN marking on this driver. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2014-03-19mfd: pm8xxx: Move pm8xxx-irq.c contents into only driver that uses itStephen Boyd4-382/+348
The pm8xxx-irq.c code is practically mandatory given that the pm8921-core driver will WARN about it missing and the Kconfig marks it as default y when a PM8xxx chips is enabled. The only reason the file was split out was because we planned to support other pm8xxx chips with different pm8xxx-core.c files. Now that we have DT on ARM this isn't necessary because we should be able to support all the ssbi based PM8xxx chips in one driver and one file with no data bloat. Let's move this code into the only driver that uses it right now (pm8921) so that it's always compiled when needed. In the future we can rename pm8921-core.c to something more generic.

2014-03-19mfd: twl6040: Remove duplicate register writeFlorian Vaussard1-1/+0
When probing, regmap_register_patch() will bypass the cache and perform i2c writes for the given patches. It is thus unnecessary to manually set the TWL6040_REG_ACCCTL register just before, as it will be done when registering the twl6040_patch.
