From 49c13b4d2dd4a831225746e758893673f6ae961c Mon Sep 17 00:00:00 2001 From: Erico Nunes Date: Fri, 5 Apr 2024 17:29:49 +0200 Subject: drm/lima: add mask irq callback to gp and pp This is needed because we want to reset those devices in device-agnostic code such as lima_sched. In particular, masking irqs will be useful before a hard reset to prevent race conditions.
