Subject: [PATCH] pcf506xx.patch
|
|
Moved shared PMU code from pcf50606.h and pcf50633.h (which prevented inclusion
|
|
of both at the same time) to pcf506xx.h
|
|
|
|
- include/linux/pcf50606.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
|
|
moved to pcf506xx.h
|
|
- include/linux/pcf50633.h (struct pmu_voltage_rail, enum pmu_event, pmu_cb):
|
|
moved to pcf506xx.h
|
|
|
|
