17  * The BD9576 has own IRQ 'blocks' for:
18  *  - I2C/thermal,
19  *  - Over voltage protection
20  *  - Short-circuit protection
21  *  - Over current protection
22  *  - Over voltage detection
23  *  - Under voltage detection
24  *  - Under voltage protection
25  *  - 'system interrupt'.
27  * Each of the blocks have a status register giving more accurate IRQ source
28  * information - for example which of the regulators have over-voltage.
31  * which of sub-blocks have active IRQs. Fine. That would fit regmap-irq main
33  *  - Only some sub-IRQs can be masked.
34  *  - The IRQ informs us about fault-condition, not when fault state changes.
40  * For now we do just use the main-IRQ register as source for our IRQ
41  * information and bind the regmap-irq to this. We leave fine-grained sub-IRQ
42  * register handling to handlers in sub-devices. The regulator driver shall
43  * read which regulators are source for problem - or if the detected error is
44  * regulator temperature error. The sub-drivers do also handle masking of "sub-
48  * disable_irq_nosync() from sub-device handler and add a delayed work to
49  * re-enable IRQ roughly 1 second later. This should keep our CPU out of
50  * busy-loop.
