[PATCH qemu.git v3 4/8] hw/timer/imx_epit: update interrupt state on CR


From: ~axelheider
Subject: [PATCH qemu.git v3 4/8] hw/timer/imx_epit: update interrupt state on CR write access
Date: Thu, 01 Dec 2022 15:42:04 -0000

From: Axel Heider <axel.heider@hensoldt.net>

The interrupt state can change due to:
- reset clears both SR.OCIF and CR.OCIE
- write to CR.EN or CR.OCIE
