From 74da272400b46f2e898f115d1b1cd60828766919 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Fri, 6 May 2022 09:47:05 +0100 Subject: soundwire: qcom: adjust autoenumeration timeout Currently timeout for autoenumeration during probe and bus reset is set to 2 secs which is really a big value. This can have an adverse effect on boot time if the slave device is not ready/reset. This was the case with wcd938x which was not reset yet but we spent 2 secs waiting in the soundwire controller probe. Reduce this time to 1/10 of Hz which should be good enough time to finish autoenumeration if any slaves are available on the bus.
