/*
* The BD9576 has own IRQ ' blocks ' for :
* - I2C / thermal ,
* - Over voltage protection
* - Short - circuit protection
* - Over current protection
* - Over voltage detection
* - Under voltage detection
* - Under voltage protection
* - ' system interrupt ' .
*
* Each of the blocks have a status register giving more accurate IRQ source
* information - for example which of the regulators have over - voltage .
*
* On top of this , there is " main IRQ " status register where each bit indicates
* which of sub - blocks have active IRQs . Fine . That would fit regmap - irq main
* status handling . Except that :
* - Only some sub - IRQs can be masked .
* - The IRQ informs us about fault - condition , not when fault state changes .
* The IRQ line it is kept asserted until the detected condition is acked
* AND cleared in HW . This is annoying for IRQs like the one informing high
* temperature because if IRQ is not disabled it keeps the CPU in IRQ
* handling loop .
*
* For now we do just use the main - IRQ register as source for our IRQ
* information and bind the regmap - irq to this . We leave fine - grained sub - IRQ
* register handling to handlers in sub - devices . The regulator driver shall
* read which regulators are source for problem - or if the detected error is
* regulator temperature error . The sub - drivers do also handle masking of " sub -
* IRQs " if this is supported / needed .
*
* To overcome the problem with HW keeping IRQ asserted we do call
* disable_irq_nosync ( ) from sub - device handler and add a delayed work to
* re - enable IRQ roughly 1 second later . This should keep our CPU out of
* busy - loop .
