From e0ea98258a81e09542cdbe239e839e9698e582dd Mon Sep 17 00:00:00 2001 From: Daniel Kurtz Date: Thu, 1 Feb 2018 15:18:38 -0700 Subject: soc/amd/stoneyridge: Add API to initialize non-early_init i2c buses Provide a method for initializing i2c buses that are not marked as early_init in the device tree. These i2c buses can be enabled in a mainboard's ramstage, for example.
