From 945b47441d83d2392ac9f984e0267ad521f24268 Mon Sep 17 00:00:00 2001 From: Lior Amsalem Date: Tue, 30 Jun 2015 16:09:49 +0200 Subject: ata: pmp: add quirk for Marvell 4140 SATA PMP This commit adds the necessary quirk to make the Marvell 4140 SATA PMP work properly. This PMP doesn't like SRST on port number 4 (the host port) so this commit marks this port as not supporting SRST.

If Linux is booted while the disk is spun down, the command that sets transfer mode causes the disk to spin up. The spin-up takes longer than the default 5s timeout, so the command fails and timeout is reported. Fix this by increasing the timeout to 15s, which is enough for the disk to spin up.
