From 44577683008010b4470c42bf7c10ba9d92780f30 Mon Sep 17 00:00:00 2001 From: Mark Hsieh Date: Tue, 23 Nov 2021 22:54:01 +0800 Subject: mb/google/brya/var/gimble: Swap TPM I2C with touchscreen I2C DVT schematic will exchange TPM_I2C3 to TPM_I2C1, that may need swap TPM I2C with touchscreen I2C to avoid TPM I2C fall on muxed ISH I2C, need change I2C map, sch amd GPIO map. b/196293623 BUG=b:207613972 TEST=USE="project_gimble emerge-brya coreboot" and verify it builds without error.
