Here we provide a means to probe and extract vital information
from Device Tree when booting with it enabled. Without this
patch sub-devices wouldn't be able to reference the tc3589x
from Device Tree.Signed-off-by: Lee Jones

In preparation for Device Tree enablement all IRQ controllers
should control their own IRQ domain. This patch provides just
that.Signed-off-by: Lee Jones

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

Guard PM methods with CONFIG_PM_SLEEP and get rid of some unneeded #ifdefs.
This fixes below build warnings:CC drivers/mfd/tc3589x.o
drivers/mfd/tc3589x.c:361:12: warning: 'tc3589x_suspend' defined but not used [-Wunused-function]
drivers/mfd/tc3589x.c:375:12: warning: 'tc3589x_resume' defined but not used [-Wunused-function]SIMPLE_DEV_PM_OPS already defines constant dev_pm_ops, thus also fix
'duplicate const' sparse warning.Signed-off-by: Axel Lin

The CONFIG_PM code was unconditionally compiled in despite
the dev_pm_ops only being included into the driver struct
if used. Fix this by adding the missing #ifdef.Signed-off-by: Linus Walleij

On the TC35892, a random delayed interrupt clear (GPIO IC) write locks up the
child interrupts. In such a case, the original interrupt is active and not yet
acknowledged. Re-check the IRQST bit for any pending interrupts and handle
those.Acked-by: Samuel Ortiz
