From ad473db4ec8d5502e35d78a034a92a520afb9964 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Tue, 17 Mar 2020 11:33:26 -0500 Subject: [PATCH] soundwire: cadence: remove automatic command retries This is a good idea on paper, but it's not recommended at all when operating in multi-master mode. It's also not recommended when doing bank switches, since the retransmission would happen at the next SSP, and the command protocol is stuck in the mean time.
