From 6e929acb73fd861c45f2b013a0d64f77b247b124 Mon Sep 17 00:00:00 2001 From: Jes Klinke Date: Tue, 1 Dec 2020 15:21:38 -0800 Subject: mb/google/volteer: ACPI nodes for volteer2_ti50 Unique among the Volteer devices, the volteer2_ti50 variant connects to the TPM via I2C. This CL introduces the proper devicestree declarations for the Linux kernel to recognize that. overridetree.cb is shared between "sub"-variants volteer2 and volteer2_ti50, so both will have two TPM nodes, the I2C being disabled by default. The odd _ti50 variant then has code in variant.c to enable the I2C node and disable the SPI node.
