Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.
Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.
Fix the build by:
1) Renaming Marvell's defined value to a more scoped name,
in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
2) Adding the missing enum, which was going to be added anyway as part
of [1].

Sure, I'll include this in my tree.

This is my mistake, I forgot to tell Jens about this dependency,
I am very sorry about that. As reported by John, this patch depends on
the addition of PHY_MODE_SATA in the PHY type enumeration. This series
([1]) has been delayed and I should have warned Jens about it. I'm fine
with the above fix though.
Kishon, will you be able to base phy-next on top of this fix? It will
be needed for the addition of the COMPHY driver.
Thanks and again, sorry for the troubles.

I'm OK with this, but it does beg the question how the patch was
tested before submitting, if it didn't build.
Is there functional breakage behind it? I currently lack online
hardware to test myself, unfortunately.

Linus, this is probably a better option in terms of what should go in to
fix that commit.

[PATCH 1/1] phy: fix build breakage: add PHY_MODE_SATA
From: John Hubbard
Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.
Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.
Fix the build by:
1) Renaming Marvell's defined value to a more scoped name,
in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.
2) Adding the missing enum, which was going to be added anyway as part
of [1].
