From 6871d51125dcf7c091c9c461c3e9b8bfa681217d Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Wed, 12 Aug 2020 20:55:41 +0800 Subject: [PATCH] mb/google/asurada: fix EC commands timeout The Asurada EC is using the large packet (256B) mode, and we were seeing lots of timeout errors on various commands. The AcceptTimeoutUs in EC SPI driver is hard-coded at 5000, and that is too small for large packet running in 1M so we should change EC SPI to the same value that kernel is using (3M).
