2014-03-19mfd: mc13xxx: Add missing spi_setup()Alexander Shiyan
The probe routine should call spi_setup() to configure the SPI bus so it can properly communicate with the device. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2014-03-19mfd: mc13xxx: Limit maximum SPI speedAlexander Shiyan
The patch adds the maximum speed limit in accordance with the PMIC datasheet if other value is not given in the devicetree description or board data. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2014-03-19mfd: timberdale: Use pci_enable_msix_exact() instead of pci_enable_msix()Alexander Gordeev
As result of deprecation of MSI-X/MSI enablement functions pci_enable_msix() and pci_enable_msi_block() all drivers using these two interfaces need to be updated to use the new pci_enable_msi_range() or pci_enable_msi_exact() and pci_enable_msix_range() or pci_enable_msix_exact() interfaces.

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 Boyd
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 Boyd
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 Vaussard
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.

2014-03-19gpio: ich: Add output levels cache supportVincent Donnefort
This patch allows GPIO driver to cache GPIO_LVL output registers. The aim is to support chipsets on which GPIO_LVL value can't be read for output pins. Caching output levels implies the first output values reading as 0. The driver so can't be aware of set values GPIOs by bootloader or BIOS.

2014-03-19mfd: da9063: Add support for production silicon variant codeOpensource [Steve Twiss]
Add the correct silicon variant code ID (0x5) to the driver. This new code is the 'production' variant code ID for DA9063. This patch will remove the older variant code ID which matches the pre-production silicon ID (0x3) for the DA9063 chip. There is also some small amount of correction done in this patch: it splits the revision code and correctly names it according to the hardware specification and moves the dev_info() call before the variant ID test.

2014-03-19mfd: 88pm800: Fix I2C device resource leak if probe failsKrzysztof Kozlowski
During probe the driver allocates two dummy I2C devices for subchips in function pm800_pages_init(). Additionally this function allocates regmaps for these subchips. If any of these steps fail then these dummy I2C devices are not freed and resources leak. On pm800_pages_init() fail the driver must call pm800_pages_exit() to unregister dummy I2C devices.

Three of the PMIC registers have some bits that are changed autonomously by the PMIC itself (some time) after being set by some component driver of the DA9052 PMIC and hence they need to be marked as volatile so that the regmap API will not cache their values.
