Hi all,
This is the VERSION 3 of the series. Sorry for the confusion, I messed
up while preparing the patches.

This series adds support for SATA using the driver model on omap platforms.
It is based on the work of Mugunthan V N <mugunthan...@ti.com> in Feb 2016
The first 2 patches are preparatory work.
The 3rd patch adds a new framework to handle PHYs in a generic manner. The idea
is to move the phy initialization out of the board-specific code into a proper
driver. The link between the phy device and the controller device is done in
by device-tree as it's done in linux. The API to control a phy has been copied
from linux, excpet that the functions are prefixed by 'generic_phy_' instead of
just 'phy_' because phy_reset() is already used to handle the Ethernet phys.
The 5th patch adds a phy driver for the pipe3 sata phy found in the
omaps/am5x/dra7x SOCs.
The 6th patch allows the device under the node ocp2scp@4a090000 to be probed.
The 7th patch implements a driver for the SATA controller found in the
omaps/am5x/dra7x SOCs.
The 8th patch is cosmetic and changes the interface of scsi_detect_dev()
The 9th patch moves the call to part_init() out of scsi_detect_dev(). This is
a preparatory work path #10.
The 10th patches fix a divide-by-0 error that happens in scsi_scan()
when DM is used and split scsi_scan() in 2 functions for clarity.
The last patch enables the DM sata by default for the dra7 platforms.
changes since v2:
* Added unit tests for generic PHY uclass.
* Changed the generic phy API to use a 'struct udevice*' to reference the phy
device.
* Don't modify anymore the root Makefile.
* Updated the Kconfig with more details on the PHY framework.
* Use a Unique Lincense Identifier (SPDX)
* Use omap5-u-boot.dtsi to mark the ocp2scp bus as compatible with "simple-bus"
* Split scsi_scan() in 2 for clarity. The function was becoming too long.
changes since v1:
* changed the way the 'old' sata code is compiled out when DM_SCSI is enabled.
* added a new framework for PHY management.
* added a new driver for the PIPE3 phy and use it in the dwc_ahci driver.
* changed the interface of scsi_detect_dev() and moved the call part_init() out
of it.
* modified the fix to scsi_scan() in order to call scsi_detect_dev() only once.
* the max_lun and max_id parameters are now taken from the device-tree.
* Updated the defconfig changes to include the PHY driver and its dependencies.
