Subject: sdhci-s3c suspends immediately
Date: Fri, 12 Apr 2013 16:20:45 +0400 [thread overview]

Hello. I'm trying to bring up sdhci-s3c driver on S3C2443 SOC.
It seems to initialize correctly, but immediately after that it get
suspended by some force. This turns off all interrupts, so SD controller
doesn't work. I don't know, where suspend command comes from, but whole
system stay in working state.
I've recorded some boot log with extended verbose for a driver. It is
attached.
I want to understand, why and where does this command come from. And how
to turn it off. Now there is no suspend support working on my board, but
i don't want to turn suspend (PM runtime) off at all, because it may be
need to set it up in future.
Please, help.
