From 0cff991179918f5618fdac7d65b7149bff6b3747 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Fri, 15 Jan 2021 14:16:51 +0800 Subject: [PATCH] soundwire: cadence: reduce timeout on transactions Currently the timeout for SoundWire individual transactions is 2s. This is too large in comparison with the enumeration and completion timeouts used in codec drivers. A command will typically be handled in less than 100us, so 500ms for the command completion is more than generous.
