7 title: ROHM BD96801 Scalable Power Management Integrated Circuit
10 - Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>
13 BD96801 is an automotive grade single-chip power management IC.
15 over-/under voltage and over current detection and a watchdog.
19 const: rohm,bd96801
26 The PMIC provides intb and errb IRQ lines. The errb IRQ line is used
27 for fatal IRQs which will cause the PMIC to shut down power outputs.
28 In many systems this will shut down the SoC controlling the PMIC and
30 where the SoC is not powered by the PMIC or has a short time backup
