Instead make the interrupt controller implementation internal and pass interrupts to the subdrivers using MFD cell resources. Note that subdrivers may either get their resources, like register block offsets, from the parent MFD or this can be included in the subdrivers directly. In the current implementation, the temperature alarm driver is generic enough to just get its base address and alarm interrupt from the parent driver, which already uses this information to implement the interrupt controller. The regulator driver, however, needs additional information like parent supplies and regulator characteristics so in that case it is easier to just augment its table with the regulator register base addresses. Similarly, the current GPIO driver already holds the number of pins and that lookup table can therefore also be extended with register offsets. Note that subdrivers can now access the two regmaps by name, even if the primary regmap is registered last so that it is returned by default when no name is provided in lookups. Finally, note that the temperature alarm and GPIO subdrivers need some minor rework before they can be used with non-SPMI devices like the PM8008. The temperature alarm MFD cell name specifically uses a "qpnp" rather than "spmi" prefix to prevent binding until the driver has been updated.

The driver is based on a driver submitted by Satya Priya, but it has been cleaned up and reworked to match the new devicetree binding which no longer describes each regulator as a separate device. This avoids describing internal details like register offsets in the devicetree and allows for extending the implementation with features like over-current protection without having to update the binding. Specifically note that the regulator interrupts are shared between all regulators. Note that the secondary regmap is looked up by name and that if the driver ever needs to be generalised to support regulators provided by the primary regmap (I2C address) such information could be added to the device-id table. This also fixes the original implementation, which looked up regulators by 'regulator-name' property rather than devicetree node name and which prevented the regulators from being named to match board schematics.
