Subject: [PATCH 076/174] sdhci-bcm2807: Increase sync_after_dma timeout
|
||
|
|
|
||
|
|
The current timeout is being hit with some cards that complete successfully with a longer timeout.
|
||
|
|
The timeout is not handled well, and is believed to be a code path that causes corruption.
|
||
|
|
872a8ff suggests that crappy cards can take up to 3 seconds to respond
