| * mfd: wm8994: Don't use system PM operationsMark Brown2013-04-09
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mfd: ab8500-core: Ignore masked out interruptsFabio Baltieri2013-04-09
| | | | | | | | | | | | | | | | | | | | | | AB8500 asserts LATCH bits for masked out interrupts. This patch explicitly masks those out using the cached mask value to prevent handle_nested_irq() being called for masked IRQ on the same register as unmasked ones.

| | | | | | | | | | | | | | | | | | | | | | | | Twelve Kconfig symbols, all related to WM8350, WM8351, and WM8352, are unused. Commit 19d57ed5a308472a02e773f33c03ad4cb2ec6a9 ("mfd: Remove custom wm8350 cache implementation") removed all their (actual) users. Remove these symbols too.

| * mfd: da9055: Change irq state to defaultAshish Jangam2013-04-09
| | | | | | | | | | | | | | | | | | | | | | | | This patch changes the irq state from high to the now default low. Because the default PMIC irq state of DA9055 got changed from high to low. This change should not affect any of the existing users since all of them use active low state. This patch has been tested on smdkv6410.

| | | | | | | | | | | | | | | | | | | | | | | | This is because we want to get rid of platform_data usage from probe(). The only information we need is PORT_MODE, and this can be supplied to us by the user (i.e. omap-usb-host.c). We also move channel clock management from runtime PM handlers into omap_tll_enable/disable(). Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| * mfd: da9055: Drop "select PMIC_DA9055"Paul Bolle2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mfd: palmas: Initialise client->of_node for dummy created clientLaxman Dewangan2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | mfd: twl4030-madc: Add support for raw value in twl4030_madc_conversionPali Rohár2013-04-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
