From 5e1c23cd392f17be9d135e504d48925a1cd92aa2 Mon Sep 17 00:00:00 2001 From: Kevin Liu Date: Mon, 23 Mar 2015 17:57:00 -0500 Subject: [PATCH] mmc: sdhci: add timeout setting for response busy command Timeout interrupt also work for response busy command(R1b) like cmd38/cmd6. So need to set it accordingly. Current code only set timeout for data command.
