3080de4ef6 mfd: arizona: Suppress needless calls to the primary IRQ
We can read back if the primary IRQ is asserted from the register map,
meaning that we can suppress polling of the interrupt status registers
when only the AoD IRQ domain is asserting.

92d801390c mfd: arizona: Disable control interface error reporting for early devices
Early revisions of the initial Arizona-based devices can generate spurious
control interface errors in certain circumstances. Avoid causing confusion
by disabling the control interface error reporting on these devices.

e102befe7a mfd: Initial support for the WM5110
The WM5110 is a highly-integrated low-power audio system for smartphones,
tablets and other portable audio devices. It combines an advanced DSP
feature set with a flexible, high-performance audio hub CODEC.

The support is based on the Arizona core driver.

966cdc96e1 mfd: arizona: Interrupt support
Several forthcoming Wolfson devices are based on a common platform
known as Arizona allowing a great deal of reuse of driver code. This
patch adds support for the interrupt controller on Arizona class devices.
Since there are two interrupt domains in the device which share a single
/IRQ pin by default we use two regmap IRQ domains with a trivial demux
interrupt domain used to distribute the interrupts to the two devices.
The devices do support multiple interrupt signals, future work will enable
support for using this feature to avoid the demux.
