From 5b574e1c859a095ecdf2728a1a6db2d854bbb668 Mon Sep 17 00:00:00 2001 From: Eric Lai Date: Thu, 23 Apr 2020 13:52:54 +0800 Subject: mb/google/deltaur: Change H1 I2C speed to STANDARD MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, Deltaur’s I2C speed has not been tuned yet, so slow down the H1 I2C to avoid I2C error for short term. Error logs: Reading cr50 TPM mode I2C receive timeout I2C read failed: bus 3 addr 0x50 BUG=b:154310066 TEST=Check H1 has no I2C error occurring and can be updated by gsctool.
