From 8da4d8840cff1bcae4accc492fbf05eae4ae591c Mon Sep 17 00:00:00 2001 From: David Wu Date: Fri, 7 Jun 2024 16:10:32 +0800 Subject: mb/google/nissa/var/riven: Add GPIO table Refer to the reference board of nivviks, and update GPIO settings based on latest schematic (Riven(ZDK)_MB_Proto_0601.pdf). BUG=b:337169542 TEST=Local build successfully.
