From 4d58e10e3e4900dbad3f44e65769092c631101cb Mon Sep 17 00:00:00 2001 From: =?utf8?q?=C5=81ukasz=20Majewski?= Date: Fri, 25 Sep 2015 18:25:25 +0200 Subject: [PATCH] mmc: dw_mmc: Increase timeout to 4 minutes (as in Linux kernel) The commit: d9dbb97be0e4a550457aec5f11afefb446169c90 "mmc: dw_mmc: Zap endless timeout" removed endless loop waiting for end of dw mmc transfer. For some workloads - dfu test @ Odroid XU3 (sending 8MiB file) - and SD cards (e.g. MicroSD Kingston 4GiB, Adata 4GiB) the default timeout is to short. The new value - 4 minutes (240 seconds) - is the same as the one used in Linux kernel driver. Such fix should be good enough until we come up with better fix for this issue.
