* mfd: twl6040: Remove duplicate register writeFlorian Vaussard2014-03-191-1/+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.

* gpio: ich: Add output levels cache supportVincent Donnefort2014-03-191-2/+19
| | | | | | | | | | | | 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.

* mfd: da9063: Add support for production silicon variant codeOpensource [Steve Twiss]2014-03-192-12/+19
| | | | | | | | | | | | | | | | 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.

* mfd: 88pm800: Fix I2C device resource leak if probe failsKrzysztof Kozlowski2014-03-191-2/+1
| | | | | | | | | | | | | | 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.
