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.Signed-off-by: Lee Jones

syscon.h header uses struct device_node in functions' declarations
without declaring it. This causes compilation warnings like:include/linux/mfd/syscon.h:20: warning: ‘struct device_node’
declared inside parameter list
include/linux/mfd/syscon.h:20: warning: its scope is only this
definition or declaration, which is probably not what you wantFix it by adding a forward declaration of struct device_node.

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.Signed-off-by: Mark Brown

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.Acked-by: Linus Walleij

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.

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

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.Signed-off-by: Paul Bolle

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 = ;
interrupt-controller;palmas_rtc {
compatible = "ti,palmas-rtc";
interrupt-parent = ;
interrupts = ;
};
::::::::::;;;
};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.Signed-off-by: Laxman Dewangan

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.Signed-off-by: Pali Rohár
