2013-04-09mfd: ab8500: sysctrl: Initialize driver at arch_initcallUlf Hansson1-1/+1
The abx500-clk driver is initiated at arch_initcall level. Moreover it is relying on the ab8500-sysctrl API to be available. Therefore move ab8500-sysctrl to arch_initcall level as well. The device is already added before the abx500 clk device, thus it will be probed before as well, which is exactly what we want.

2013-04-09mfd: db8500-prcmu: Return early if the TCPM cannot be locatedLee Jones1-19/+21
Currently we check to see if we obtained the Tightly Coupled Program Memory (TCPM) base and only execute the code within the check if we have it. It's more traditional to return early if we don't have it. This way we can flatten most of the function's code down to a single tab spacing.

2013-04-09mfd: wm8994: Don't use system PM operationsMark Brown1-3/+4
For realistic systems the power management is controlled entirely via runtime PM - if the device is not runtime suspended then the suspend will abort without doing anything as functionality such as accessory detection or audio bypass will require the device to be enabled while if the device is runtime suspended it is already in the lowest power state. This means that system suspend is redundant and can be removed which avoids issues with attempting to double disable the regulators.

The Kconfig entry for DA9055 PMIC Support selects PMIC_DA9055. That was probably inspired by the similar select statement in the entry for DA9052/53 PMIC with I2C. But the DA9055 PMIC only comes in an I2C variant and its driver doesn't need a separate Kconfig symbol for shared code. In any case, this select can be dropped as PMIC_DA9055 doesn't exist.

2013-04-08mfd: palmas: Initialise client->of_node for dummy created clientLaxman Dewangan1-0/+1
Palmas device have three different i2c addresses. The device creates the two new dummy i2c clients for accessing the register by using primary client adapter. This new dummy i2c client have their of_node as NULL. The dummy i2c client is used for registering interrupt and on this, it creates irq domain handle. This created irq domain handle has their of_node as NULL. Now when any child of this device is registered through the DT as follows: palmas: tps65913@58 { :::::::::::::::::: #interrupt-cells = <2>; interrupt-controller; palmas_rtc { compatible = "ti,palmas-rtc"; interrupt-parent = <&palmas>; interrupts = <8 0>; }; ::::::::::;;; }; And child driver (palam-rtc in this case) get their irq number as irq = platform_get_irq(pdev, 0); The returned irq number is error in this case. The reason is that the created irq_domain handle for the palmas interrupt does not have valid node and so matching of node fails with palmas node. Hence initialising the newly dummy created client->of_node with the primary clients of_node so that irq_domain handle have proper of_node for matching.

2013-04-08mfd: twl4030-madc: Add support for raw value in twl4030_madc_conversionPali Rohár1-4/+10
Driver twl4030-madc has hardcoded channel types (10 - battery current, 1 - battery temperature) and also conversation data in variable twl4030_divider_ratios. These hardcoded channels are incorrect for Nokia RX-51 board (where is channel 0 - battery temperature). For Nokia RX-51 there is rx51_battery power_supply driver which reporting battery information via twl4030_madc_conversion. But this driver needs raw values (not converted via some hardcoded functions). So this patch adding new parameter "raw" to struct twl4030_madc_request which tell twl4030-madc driver to not convert values, but rather return raw.
