[PATCH v5 2/6] DONOTMERGE: arm64: dts: ti: Add pinmux and irq mapping for TPS65219 external interrupts

Jerome Neanne jneanne at baylibre.com
Tue Sep 13 05:14:15 PDT 2022


Interrupt occurring on PMIC TPS65219 is propagated to SOC
through EXTINTn pin connected to gic500 interrupt controller

Needed for driver testing but official board support pending.
TI commitment is required before board upstream kick-off.
