From 50d10d9271f6c6542196c54275091c7b2c6edf97 Mon Sep 17 00:00:00 2001 From: Sunil Khatri Date: Wed, 24 Jul 2024 22:35:56 +0530 Subject: [PATCH] drm/amdgpu: add macro to calculate offset with instance Add macro definition which calculate offset of the register with index override. This is useful in case when there is an array of registers which is common for all instances. To read registers in that case it is easy to define registers once and the index value is manually passed to calculate proper offset of register for each instance.
