 - And then the series that I hinted at from last week, which removes
   the sqe from the io_kiocb and keeps all sqe handling on the prep
   side. This guarantees that an opcode can't do the wrong thing and
   read the sqe more than once. This is unchanged from last week, no
   issues have been observed with this in testing. Hence I really think
   we should fold this into 5.5.

      ata: ahci_brcm: Add missing clock management during recovery · bf0e5013
      Florian Fainelli authored 
      The downstream implementation of ahci_brcm.c did contain clock
management recovery, but until recently, did that outside of the
libahci_platform helpers and this was unintentionally stripped out while
forward porting the patch upstream.

Add the missing clock management during recovery and sleep for 10
milliseconds per the design team recommendations to ensure the SATA PHY
controller and AFE have been fully quiesced.

      ata: ahci_brcm: BCM7425 AHCI requires AHCI_HFLAG_DELAY_ENGINE · 1a3d78cb
      Florian Fainelli authored 
      Set AHCI_HFLAG_DELAY_ENGINE for the BCM7425 AHCI controller thus making
it conforming to the 'strict' AHCI implementation which this controller
is based on.

This solves long link establishment with specific hard drives (e.g.:
Seagate ST1000VM002-9ZL1 SC12) that would otherwise have to complete the
error recovery handling before finally establishing a succesful SATA
link at the desired speed.

We re-order the hpriv->flags assignment to also remove the NONCQ quirk
since we can set the flag directly.

      ata: ahci_brcm: Fix AHCI resources management · c0cdf2ac
      Florian Fainelli authored 
      The AHCI resources management within ahci_brcm.c is a little
convoluted, largely because it historically had a dedicated clock that
was managed within this file in the downstream tree. Once brough
upstream though, the clock was left to be managed by libahci_platform.c
which is entirely appropriate.

This patch series ensures that the AHCI resources are fetched and
enabled before any register access is done, thus avoiding bus errors on
platforms which clock gate the controller by default.

As a result we need to re-arrange the suspend() and resume() functions
in order to avoid accessing registers after the clocks have been turned
off respectively before the clocks have been turned on. Finally, we can
refactor brcm_ahci_get_portmask() in order to fetch the number of ports
from hpriv->mmio which is now accessible without jumping through hoops
like we used to do.

The commit pointed in the Fixes tag is both old and new enough not to
require major headaches for backporting of this patch.

("libahci_platform: Staticize ahci_platform_<en/dis>able_phys()") we are

commit for ahci_brcm.c in order to properly control the PHY
initialization order.

Also make sure the function prototypes are declared in
include/linux/ahci_platform.h as a result.

      libata: Fix retrieving of active qcs · 8385d756
      Sascha Hauer authored 
      ata_qc_complete_multiple() is called with a mask of the still active
tags.

mv_sata doesn't have this information directly and instead calculates
the still active tags from the started tags (ap->qc_active) and the
finished tags as (ap->qc_active ^ done_mask)

Since 28361c40 the hw_tag and tag are no longer the same and the
equation is no longer valid. In ata_exec_internal_sg() ap->qc_active is
initialized as 1ULL << ATA_TAG_INTERNAL, but in hardware tag 0 is
started and this will be in done_mask on completion. ap->qc_active ^
done_mask becomes 0x100000000 ^ 0x1 = 0x100000001 and thus tag 0 used as
the internal tag will never be reported as completed.

This is fixed by introducing ata_qc_get_active() which returns the
active hardware tags and calling it where appropriate.

This is tested on mv_sata, but sata_fsl and sata_nv suffer from the same
problem. There is another case in sata_nv that most likely needs fixing
as well, but this looks a little different, so I wasn't confident enough
to change that.
