2014-03-19mfd: twl6040: Check for error when reading revision registerFlorian Vaussard1-0/+5
We may have an error when reading the revision register, so check for the returned value. Acked-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch> Signed-off-by: Lee Jones <lee.jones@linaro.org>
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.

2014-01-21mfd: twl6040: Fix sparse non static symbol warningWei Yongjun1-1/+1
Fixes the following sparse warning: drivers/mfd/twl6040.c:89:20: warning: symbol 'twl6040_patch' was not declared. Should it be static? Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2013-12-19mfd: twl6040: reg_defaults support for regmapPeter Ujfalusi1-3/+89
Add reg_defaults to regmap and at the same time implement proper power state handling with using regcache_cache_only(), regcache_sync() and regcache_mark_dirty(). This will make sure that we do not need to do restore operations in child drivers anymore.

mfd-lee-3.13-1 MFD patches due for v3.13.
2013-10-24mfd: twl6040: Remove obsolete cleanup for i2c clientdataWolfram Sang1-6/+2
A few new i2c-drivers came into the kernel which clear the clientdata-pointer on exit or error. This is obsolete meanwhile, the core will do it. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2013-10-23mfd: twl6040: Drop devm_free_irq of devm_ allocated irqWei Yongjun1-8/+2
The devm_request_irq function allocates irq that is released when a driver detaches. Thus, there is no reason to explicitly call devm_free_irq in probe or remove functions. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2013-09-02mfd: twl6040: Use regmap for register cacheMark Brown1-13/+30
Rather then open coding a cache of the vibra control registers use the regmap cache code. Also cache the interrupt mask register, providing a small performance improvement for the interrupt code.

2013-07-31mfd: twl6040: Remove support for legacy (pdata) modePeter Ujfalusi1-42/+13
TWL6040 is used only with OMAP4/5 SoCs and they can only boot in in DT mode. The support for pdata/legacy boot can be removed. Add TODO comment to the header file that all pdata struct can be removed in the next merge window (after the sub driver updates are in).

2013-01-03Drivers: mfd: remove __dev* attributes.Greg Kroah-Hartman1-4/+4
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-11-13mfd: twl6040: Rename the core driverPeter Ujfalusi1-0/+749
After the regmap_irq conversion there is no need to call the driver as twl6040-core.c since there is only one c file remained. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
