From 6a4a745c42a23c5ffca0f0c76ca2ed2593b9389b Mon Sep 17 00:00:00 2001 From: Luben Tuikov <luben.tuikov@amd.com> Date: Mon, 14 Nov 2022 20:48:40 -0500 Subject: drm/amdgpu: Allow non-standard EEPROM I2C address Allow non-standard EEPROM I2C address of 0x58, where the Device Type Identifier is 1011b, where we form 1011000b = 0x58 I2C address, as on some ASICs the FRU data lives there.
