From 5f86b0b7e3153240cfee3dbaade0428c8055ba5b Mon Sep 17 00:00:00 2001 From: Eric Lai Date: Mon, 1 Jun 2020 14:37:47 +0800 Subject: [PATCH] mb/google/deltaur: Change H1 I2C speed to FAST H1 is stable after HW rework. Connect +3.3V_ALW_PCH with +3.3V_PRIM. Therefore change I2C speed back to FAST. BUG=b:154885320 TEST=Check H1 I2C speed is 375kHz by scope. And no error message in cbmem and kernel log.
