Subject: [PATCH 017/174] sdhci-bcm2708: raise DMA sync timeout
|
||
|
|
|
||
|
|
Commit d64b84c by accident reduced the maximum overall DMA sync
|
||
|
|
timeout. The maximum overall timeout was reduced from 100ms to 30ms,
|
||
|
|
which isn't enough for many cards. Increase it to 150ms, just to be
|
||
|
|
extra safe. According to commit 872a8ff in the MMC subsystem, some
|
||
|
|
cards require crazy long timeouts (3s), but as we're busy-waiting,
|
||
|
|
and shouldn't delay for such a long time, let's hope 150ms will be
|
||
|
|
enough for most cards.
