IRQ numbers in axp20x devices are defined with high-order bit first
in each IRQ enable/status registers. On Intel platforms it is more
common to number IRQs with least significant bit first. Therefore,
sharing IRQ# between the two is very difficult. Since AXP288 is a
customized PMIC for Intel platform and the amount of shared IRQs are
very small, we use separate IRQ numbering. This also fixes collision
and a duplicate in WBTO interrupt.

e.g. For the 16 interrupts controlled in IRQ enabled registers 1 & 2,
on axp20x for ARM, the PMIC local IRQ numbers and register bits are
mapped as:
IRQ#:  0  1  2  3  4  5  6  7      8  9 10 11 12 13 14 15
---------------------------------------------------------
ARM:   7  6  5  4  3  2  1  0      7  6  5  4  3  2  1  0
Intel: 0  1  2  3  4  5  6  7      0  1  2  3  4  5  6  7

X-Powers AXP288 is a customized PMIC for Intel Baytrail-CR platforms. Similar
to AXP202/209, AXP288 comes with USB charger, more LDO and BUCK channels, and
AD converters. It also provides extended status and interrupt reporting
capabilities than the devices currently supported in axp20x.c.

In addition to feature extension, this patch also adds ACPI binding for
enumeration.

This consolidated driver should support more X-Powers' PMICs in both device
tree and ACPI enumerated platforms.

Commit 43fef47f (mfd: twl4030-power: Add a configuration to turn
off oscillator during off-idle) added support for configuring the PMIC
to cut off resources during deeper idle states to save power.

This however caused regression for n900 display power that needed the
PMIC configuration to be disabled with commit d937678a (ARM: dts:
Revert enabling of twl configuration for n900).

Turns out the root cause of the problem is that we must use
TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling
regulators that may have been enabled before the init function
for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the
regulator framework control the regulators like it should. Here we
need to only configure the sys_clken and sys_off_mode triggers for
the regulators that cannot be done by the regulator framework as
it's not running at that point.

This allows us to enable the PMIC configuration for n900.

The flag when set, can excite code that improperly uses the

Instead it clears all of the other bits disabling all of the ports in

We only request the control interface error IRQ if we set ctrlif_error,
as such we should only free it in that situation. Otherwise we will
attempt to free an IRQ we never requested and get a warning from the IRQ
core.

This patch moves the ctrlif_error variable into the arizona structure
and checks it in all cases we free the control interface error IRQ.
