[v2] arm64: dts: ti: k3-am62: Add wakeup-sources for low power modes

[PATCH v2 1/7] arm64: dts: ti: k3-pinctrl: Add WKUP_EN flag

Posted by Markus Schneider-Pargmann 1 month, 3 weeks ago

WKUP_EN is a flag to enable pin wakeup. Any activity will wakeup the SoC
in that case.

FYI: A series by Akash [1] has been picked in linux-next. It includes 
the WKUP_EN macro but defined differently as PIN_WKUP_EN. The series 
needs to be rebased to account for that macro.
