8a745f1f39 libata: Power off empty ports
Give users the option of completely powering off unoccupied
SATA ports using the existing min_power link_power_management_policy
option.  When the use selects this option on an empty port, we
will power the port off by setting DET to off.  For occupied ports,
behavior is unchanged.

0afc6f5ba9 libata-pmp: add support for Thermaltake BlackX Duet esata drive dock
Some errors still show up, but the dock works, both drives can be
accessed at the same time

The chip maker and designation is unknown - possibly jmicron JMB350?

bfeec8ca15 ATA: Don't powerdown Compaq Triflex IDE device on suspend
Don't powerdown Compaq Triflex IDE device on suspend

This fixes APM suspend on Compaq Armada 7400.
APM BIOS doesn't suspend if IDE is powered down when suspending.
The Triflex controller is found only on old Compaq boards,
so this patch will hopefully have no side effects.

5f4e206666 libata: Use Maximum Write Same Length to report discard size limit
Previously we used Maximum Unmap LBA Count in the Block Limits VPD to
signal the maximum number of sectors we could handle in a single Write
Same command.

Starting with SBC3r26 the Block Limits VPD has an explicit limit on the
number of blocks in a Write Same. This means we can stop abusing a field
related to the Unmap command and let our SAT use the proper value in the
VPD (Maximum Write Same Length).

9281b16caa pata_cm64x: fix boot crash on parisc
The old IDE cmd64x checks the status of the CNTRL register to see if
the ports are enabled before probing them.  pata_cmd64x doesn't do
this, which causes a HPMC on parisc when it tries to poke at the
secondary port because apparently the BAR isn't wired up (and a
non-responding piece of memory causes a HPMC).

Fix this by porting the CNTRL register port detection logic from IDE
cmd64x.  In addition, following converns from Alan Cox, add a check to
see if a mobility electronics bridge is the immediate parent and forgo
the check if it is (prevents problems on hotplug controllers).

ae01b2493c (libata: Implement ATA_FLAG_NO_DIPM and apply it to mcp65)
added ATA_FLAG_NO_DIPM and made ata_eh_set_lpm() check the flag.
However, @ap is NULL if @link points to a PMP link and thus the

This reverts commit 270dac35c2.

The commits causes command timeouts on AC plug/unplug.  It isn't yet
clear why.  As the commit was for a single rather obscure controller,
revert the change for now.

The problem was reported and bisected by Gu Rui in bug#34692.

270dac35c2 libata: ahci_start_engine compliant to AHCI spec
At the end of section 10.1 of AHCI spec (rev 1.3), it states

Software shall not set PxCMD.ST to 1 until it is determined that
a functoinal device is present on the port as determined by
PxTFD.STS.BSY=0, PxTFD.STS.DRQ=0 and PxSSTS.DET=3h

Even though most AHCI host controller works without this check,
specific controller will fail under this condition.

7b3a24c57d ahci: don't enable port irq before handler is registered
The ahci_pmp_attach() & ahci_pmp_detach() unmask port irqs, but they
are also called during port initialization, before ahci host irq
handler is registered. On ce4100 platform, this sometimes triggers
"irq 4: nobody cared" message when loading driver.

Fixed this by not touching the register if the port is in frozen
state, and mark all uninitialized port as frozen.

4ac7534a7f sata_fsl: Fix wrong Device Error Register usage
When a single device error is detected, the device under the error
is indicated by the error bit set in the DER. There is a one to one
mapping between register bit and devices on Port multiplier(PMP)
i.e. bit 0 represents PMP device 0 and bit 1 represents PMP device
1 etc.

Current implementation treats Device error register value as device
number not set of bits representing multiple device on PMP. It is
changed to consider bit level.

No need to check for each set bit as all command is going to be
aborted.

60a230e4a6 ata/pata_arasan_cf: fill dma chan->private from pdata->dma_priv
Some DMA controllers (eg: drivers/dma/dw_dmac*) allow platform specific
configuration for dma transfers. User drivers need to set chan->private field
of channel with pointer to configuration data. This patch takes dma_priv data
from platform data and passes it to chan->private_data, in order to pass
platform specific configuration to DMAC controller.
