From 152dca4ea77e575b21c5ee96c582fc1083a25f8a Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Tue, 14 Oct 2025 14:30:35 -0500 Subject: drm/amd: Add a helper to tell whether an IP block HW is enabled There is already a helper for telling if a block is valid, but if IP handling wants to check if it's HW is enabled no such helper exists.
