f3e6ef13e2The interrupt handler distinguishes the rail that reported the fault, but
the body ignores it. Every SW interrupt walks the regulator array looking
for the name "SW3" and every LDO interrupt looks for "LDO3", so an
over-current on SW1 is reported to the consumers of SW3 while the
consumers of SW1 hear nothing.
The lookup itself is unreliable as well. rdev_get_name() returns the
device tree regulator-name property whenever the board supplies one, and
only falls back to the name in the driver descriptor when it does not.
The binding example for this device sets regulator-name to "sw3" and
"ldo3", which strcmp() does not match against the upper case literals
used here, so a board that follows the documentation gets no over-current
notification at all. A board that names its rails after the schematic
does not match either. No other driver in the tree selects a notification
target this way.
Replace the name lookup with rdev_get_id(), which returns the descriptor
id set by the driver and cannot be overridden from the device tree, and
take both the id and the event from a table indexed by the interrupt.
The die temperature interrupts keep notifying every regulator since they
report a chip wide condition.
