The LTC3676_IRQSTAT_* bit definitions do not match the IRQSTAT
(Interrupt Request Status) register layout documented in Table 15
of the LTC3676/LTC3676-1 datasheet:
bit 0 - Pushbutton Status Active
bit 1 - Hard Reset Occurred
bit 2 - PGOOD Timeout Occurred
bit 3 - Undervoltage Warning
bit 4 - Undervoltage Standby (Fault) Occurred
bit 5 - Overtemperature Warning
bit 6 - Overtemperature Standby (Fault) Occurred
bit 7 - Reserved
The driver instead defines these starting at bit 3, one bit higher
than the datasheet specifies, which causes ltc3676_regulator_isr()
to check the wrong status bits and misreport (or miss) PGOOD
timeout, undervoltage and thermal warning/fault conditions.
Fix the bit offsets to match the datasheet.

Thanks!
[1/1] regulator: ltc3676: Fix incorrect IRQSTAT bit offsets
https://git.kernel.org/broonie/regulator/c/50dce2e2f84b
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
