From ce8f7d95899c2869b47ea6ce0b3e5bf304b2fff4 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 1 May 2025 13:00:16 -0400 Subject: Revert "drm/amd: Stop evicting resources on APUs in suspend" This reverts commit 3a9626c816db901def438dc2513622e281186d39. This breaks S4 because we end up setting the s3/s0ix flags even when we are entering s4 since prepare is used by both flows. The causes both the S3/s0ix and s4 flags to be set which breaks several checks in the driver which assume they are mutually exclusive.

Adding the 2 GPIO resources required for ISP_v4_1_1 in amdgpu_isp driver. - GPIO 0 to allow sensor driver to enable and disable sensor module. - GPIO 85 to allow ISP driver to enable and disable ISP RGB streaming mode.
