From fd14786071021bb63b0ab32b95257a594e46f8d4 Mon Sep 17 00:00:00 2001 From: Pratap Nirujogi Date: Thu, 29 May 2025 15:21:48 -0400 Subject: drm/amd/amdgpu: Add ISP Generic PM Domain (genpd) support AMDISP I2C device requires to power on ISP HW to probe the sensor device. Instead of using the exported symbols from ISP driver to control the power and clocks remotely,added Generic PM Domain (genpd) support in amdgpu_isp device for its child devices (amd_isp_capture, amd_isp_i2c_designware) to set power and clocks using PM methods.
