[PATCH v12 2/4] irqchip/loongarch-avec: Prepare for interrupt redirection support
From: Tianyang Zhang
Date: Tue May 12 2026 - 21:31:16 EST
Interrupt redirection support requires a new interrupt chip, which needs
to share data structures, constants and functions with the AVECINTC code.
So move them to the header file and make the required functions public.
