From fe8637f7708c16765ecf4035813efbfdd2c9be10 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Wed, 24 May 2023 13:36:19 -0700 Subject: scsi: ufs: core: Increase the START STOP UNIT timeout from one to ten seconds One UFS vendor asked to increase the UFS timeout from 1 s to 3 s. Another UFS vendor asked to increase the UFS timeout from 1 s to 10 s. Hence this patch that increases the UFS timeout to 10 s. This patch can cause the total timeout to exceed 20 s, the Android shutdown timeout. This is fine since the loop around ufshcd_execute_start_stop() exists to deal with unit attentions and because unit attentions are reported quickly. Fixes: dcd5b7637c6d ("scsi: ufs: Reduce the START STOP UNIT timeout") Fixes: 8f2c96420c6e ("scsi: ufs: core: Reduce the power mode change timeout") Acked-by: Adrian Hunter Reviewed-by: Stanley Chu Reviewed-by: Bean Huo Signed-off-by: Bart Van Assche Link: https://lore.kernel.org/r/20230524203659.1394307-2-bvanassche@acm.org Signed-off-by: Martin K.
