Palmas device supports multiple i2c device address and the client
for these addressed are created in the driver as i2c_new_dummy().The new devices are not getting released in error or removal path and
so it is causing resource leak.Add the unregister of these newly created dummy devices to avoid resource
leaks.Signed-off-by: Laxman Dewangan

The Patch adds TPS659038 PMIC support in the palmas mfd driver.
The TPS659038 has almost the same registers as of the earlier
supported variants of PALMAS family such as the TWL6035.The critical differences between TPS659038 and TWL6035 being:
1) TPS659038 has nothing related to battery charging and back up battery stuff.
2) TPS659038 does not have does not have SMPS10(Boost) step up convertor.
3) TPS659038 does not have Battery detection and anything related to battery.
4) SD card detection, Battery presence detection, Vibrator, USB OTG are missing
when compared to TWL6035.Signed-off-by: J Keerthy

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

Currently driver sets the irq type to IRQF_TRIGGER_LOW which is
causing interrupt registration failure in ARM based SoCs as:
[ 0.208479] genirq: Setting trigger mode 8 for irq 118 failed (gic_set_type+0x0/0xf0)
[ 0.208513] dummy 0-0059: Failed to request IRQ 118: -22Provide the irq flags through platform data if device is registered
through board file or get the irq type from DT node property in place
of hardcoding the irq flag in driver to support multiple platforms.Also configure the device to generate the interrupt signal according to
flag type.Signed-off-by: Laxman Dewangan

Palma RTC is capable of generating alarm interrupt. Pass the alarm interrupt
as IRQ_RESOURCE for palmas-rtc sub device driver so that rtc driver can get
irq as platform_get_irq().Also pass the irq domain in mfd_add_devices() to properly offset the irqs for
sub devices. This is needed when adding device through DT.Signed-off-by: Laxman Dewangan

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.Signed-off-by: Mark Brown
