If anyone has any objections, please let me know. ------------------ From: Val Packett [ Upstream commit 4b15b03166cc5d28e9912287b1f9b6607c8710ec ] i2c20 is used by the battmgr service on the ADSP to communicate with the SBS interface of the battery. Initializing it from Linux would break the battmgr functionality when booted in EL2. Mark those pins as reserved.
