* mfd: twl6040: Optional clk32k clock handlingPeter Ujfalusi2014-06-03
| | | | | | | | | | | In certain boards the source for the clk32k clock can be gated. In these boards the clk32k clock can be provided to the driver and it is going to be enabled/disabled when it is needed. If the clk32k clock is not provided the driver will assume that it is always running. Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: twl6040: Select i2c fast mode as default with regmap patchPeter Ujfalusi2014-06-03
| | | | | | | | | All boards using twl6040 configures the i2c bus to 400KHz. While twl6040's defaults to normal mode (100KHz). So far twl6040 has no problem with i2c communication in this configuration it is safer to select fast i2c mode.

* mfd: twl6040: Clear the interrupt ID register before requesting IRQPeter Ujfalusi2014-06-03
| | | | | | | | | | | If for some reason the boot loader enabled the audpwron GPIO we will have pending IRQs to be handled. This seams to break twl6040 for some reason leading to non working i2c communication (i2c timeouts). Clearing the INTID register after we requested the audpwron GPIO (and set it to low) will ensure that the chip will operate normally in this case as well.

* mfd: core: Don't use devres functions before device is addedCharles Keepax2014-06-03
| | | | | | | | | | | | | | | | The supply aliases for the MFD devices were being added using devres but the device hasn't been added at this point and as such we can't use devres. The MFD already has a function that removes devices this patch uses the non-devres versions of the supply alias functions and adds an unregister in mfd_remove_devices_fn.

* mfd/rtc: s5m: Do not allocate RTC I2C dummy and regmap for unsupported chipsetsKrzysztof Kozlowski2014-06-03
| | | | | | | | | | | | | | | | | | The rtc-s5m driver does not support all of S2M and S5M chipsets supported by main MFD sec-core driver. For such chipsets unsupported by rtc-s5m, the MFD sec-core driver initialized regmap with default config. This config in such cases wouldn't work at all. The main MFD sec-core driver shouldn't initialize regmap for child drivers which is not used by them and even not valid. Move the allocation of RTC I2C dummy device and initialization of RTC regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m driver will use proper regmap config for supported devices.

This means voltage scaling does not do anything when booted with device tree. Turns out the reason is we fail to initialize the SmartReflex enable bit in twl4030 with the following error: twl: not initialized And that happens because we are wrongly tinkering with the twl4030 registers in arch/arm/mach-omap2/omap_twl.c before the driver is initialized. Looking at the the SmartReflex bit enable code in omap_twl.c, we need to always set it. So let's fix the issue by always enabling the twl4030 SmartReflex bit in the drivers/mfd/twl-core.c probe, and drop the related code in omap_twl.c. Note that we still have some twl4030 tinkering left in omap_twl.c for the twl6030 case, but that's a different patch.

The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the PMIC block. The PMIC block has different I2C slave address and uses own regmap so another regmap_irq_chip is needed. Since we have two regmap_irq_chip, use shared interrupts on MAX77836. This patch adds additional defines and functions to the max14577 MFD core driver so the driver will handle both chipsets.

This patch introduces two macros which can be used for iteration over cpufreq_frequency_table keeping a common coding style across drivers: - cpufreq_for_each_entry: iterate over each entry of the table - cpufreq_for_each_valid_entry: iterate over each entry that contains a valid frequency.
