Subject: [PATCH] libata: add waits for GoVault
|
|
References: 246451

Patch-mainline: not yet
|
|
|
|
Iomega GoVault drives need specific waits here and there. Upstream
|
|
approach hasn't been determined yet. This is temp solution from Gary
|
|
Hade. Read the following thread for details.

|
|
|
|
With recent changes in the reset sequence (ATA_TMOUT_FF_WAIT and
|
|
prefer-hardreset), the only thing which needs adjustment is
|
|
ATA_TMOUT_FF_WAIT (the prereset wait part is unnecessary as the wait
|
|
is necessary only for softreset when SCR registers are accessible and
|
|
in those cases libata now always uses hardreset which doesn't require
|
|
such wait).
