After debugging, the reason is -found that the value of Port-x FIS-based Switching Control -(PxFBS@0x40) became wrong. -According to design, the bits[11:8, 0] of register PxFBS -are cleared when Port Command and Status (0x18) bit[0] -changes its value from 1 to 0, i.e. falling edge of Port -Command and Status bit[0] sends PULSE that resets PxFBS -bits[11:8; 0]. -So it needs save the port PxFBS register before PxCMD -ST write and restore the port PxFBS register afterwards -in ahci_stop_engine(). - -This commit allows drivers to override ahci_stop_engine -behavior for use by the Marvell AHCI driver(and potentially -other drivers in the future). - -Signed-off-by: Evan Wang -Cc: Ofer Heifetz -Cc: Tejun Heo -Cc: Thomas Petazzoni -Signed-off-by: Tejun Heo ---- - drivers/ata/ahci.c | 6 +++--- - drivers/ata/ahci.h | 7 +++++++ - drivers/ata/ahci_qoriq.c | 2 +- - drivers/ata/ahci_xgene.c | 4 ++-- - drivers/ata/libahci.c | 20 ++++++++++++-------- - drivers/ata/sata_highbank.c | 2 +- - 6 files changed, 26 insertions(+), 15 deletions(-) - -diff --git a/drivers/ata/ahci.c b/drivers/ata/ahci.c -index 1ff17799769d0..6389c88b3500a 100644 ---- a/drivers/ata/ahci.c -+++ b/drivers/ata/ahci.c -@@ -698,7 +698,7 @@ static int ahci_vt8251_hardreset(struct ata_link *link, unsigned int *class, - - DPRINTK("ENTER\n");
