Hi,

Now that miphy28lp phy is present upstream we can add sata DT nodes for
stih407 family silicon. As part of testing this I found a hang
with the current driver implmentation which does some register writes
before enabling the IP clock. Presumably on stih416 devices the sata
clock must have already been enabled by the targetpack/bootloader.

This series also tidys up some inaccuracies in the DT documentation
where the doc hasn't kept aligned with the driver. In addtion to these
fixes I've also added an example for stih407 silicon.

Changes in RESEND:
- Rebased on v4.0-rc6 (Pete)
- Applied Acks (Pete)

Peter Griffin (3):
  ahci: st: Update the ahci_st DT documentation
  ARM: DT: STi: STiH407: Add sata DT nodes.
  ahci: st: st_configure_oob must be called after IP is clocked.

As part of testing ahci_st driver working on stih407 I noticed
several things wrong in the DT documentation: -

1) Compatible string doesn't match the driver code
2) pwr-rst reset isn't documented (but exists in the driver)
3) some whitespace issues (spaces not tabs)

Also add in a stih407 family example into the doc.

Now that the miphy28lp is upstream, we can add the sata dt nodes
for stih407 family silicon. This has been tested on b2120 board
J4 (sata0 channel). These nodes are disabled by default as a
special mini pci-e to sata daughter board is required which
isn't shipped with the board.

Currently the ahci_st driver will hang the system on probe, as the
st_configure_oob function does some register writes before the IP
is clocked. This patch moves the function call to after
ahci_platform_enable_resources (which enables the IP clock), and
resolves the hang.

Addtionally st_ahci_configure_oob should be called in the st_ahci_resume
function, so we also rectify that ensuring it is also called after
the IP clock has been enabled.

How should this patch be routed?  Should I pick this up and apply to
libata/for-4.1 or should it go together with the other patches?  If
the latter, please feel free to add my acked-by.

I think you can pick patches 1 & 3.
I will apply patch 2 to STi DT branch.

This patch (and also the DT documentation change) can go via your tree. Maxime
will take the stih407 DT patch.

Hmmm... The first patch doesn't apply to libata/for-4.1?

I was just investigating this, and you don't have the patch I sent on 25th February
entitled "ahci: st: Update the DT example for how to obtain the PHY."

I also did a re-send yesterday with ack's collected here https://lkml.org/lkml/2015/3/30/404.

However both times it seems I didn't add you to the email :-( which certainly explains
why you don't have it.

If I re-send that patch with you on CC can you take and apply it as well? That would
preserve the ack's.

regards,

Peter.
