This patch set catches up with latest Berlin improvements provided by Antoine - in particular SATA PHY support and AHCI generic for Berlin BG2. Marvell BSP code for BG2 suggests more differences between the two PHY revisions found on BG2 and BG2Q, but the only important one seems to be the PHY_BASE used in AHCI vendor-specific registers. I also confirmed that power_off does indeed power off the PHY on BG2, too (It wasn't very clear in BSP code). Anyway, I have tested this on BG2-based Sony NSZ-GS7 and attached SATA HDD is successfully detected and partitions are displayed. The patches are currently based on next-20141009 and I plan to resend once v3.18-rc1 drops. A branch based on next-20141009 with this patches applied can be found on git://git.infradead.org/users/hesselba/linux-berlin.git devel/bg2-sata-v1 Patch 1 prepares phy-berlin-sata to support different PHY_BASE addresses by moving the constant to driver private data. Patches 2 and 3 add a new compatible to driver and DT documentation that reflects the differences between BG2Q and BG2 SATA PHY. Patches 4 and 5 finally add DT nodes to both Berlin2 SoC dtsi and Sony NSZ-GS7 board DT file. SATA plug on NSZ-GS7 is unpopulated but can be very easily equipped with SATA receptable and some 0402 caps. I decided to enable SATA by default although not all users may populate it.
