[v1] Misc fixups and changes for Kontron i.MX8M and i.MX93 DTs

[PATCH 10/12] arm64: dts: imx93-kontron: Add RTC interrupt signal

Posted by Frieder Schrempf 2 months, 3 weeks ago

From: Frieder Schrempf <frieder.schrempf@kontron.de>

The RTC EVI ouptut is connected to a GPIO. Add the interrupt
so it can be used by the RTC driver.

AFAIK, RV3028's EVI is an input pin (EVent Input).

Please check.

BR,

Thanks for noticing! It seems like the commit message is wrong here. The
patch is about the INT signal which is an output on the RTC. I will fix
the description in v2.

Thanks
