[U-Boot] [PATCH v2 00/10] OMAP: Move SATA to use block driver model

[Jean-Jacques Hiblot]

This series adds support for SATA using the driver model on omap platforms.
It is based on the work of Mugunthan V N <mugunthanvnm at 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 4th patch adds a phy driver for the pipe3 sata phy found in the
omaps/am5x/dra7x SOCs.
The 5th patch allows the device under the node ocp2scp at 4a090000 to be probed.
The 6th patch implements a driver for the SATA controller found in the
omaps/am5x/dra7x SOCs.
The 7th patch is cosmetic and changes the interface of scsi_detect_dev()
The 8th patch moves the call to part_init() out of scsi_detect_dev(). This is
a preparatory work path #9.
The 9th patches fix a divide-by-0 error that happens in scsi_scan()
when DM is used.
The last patch enables the DM sata by default for the dra7 platforms.


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.


Jean-Jacques Hiblot (8):
  arm: omap: sata: compile out board-level sata code when CONFIG_DM_SCSI
    is defined
  drivers: phy: add generic PHY framework
  drivers: phy: add PIPE3 phy driver
  dra7: dtsi: mark ocp2scp bus compatible with "simple-bus"
  scsi: make the LUN a parameter of scsi_detect_dev()
  scsi: move the partition initialization out of the scsi detection
  dm: scsi: fix divide-by-0 error in scsi_scan()
  defconfig: dra7xx_evm: enable CONFIG_BLK and disk driver model for
    SCSI

Mugunthan V N (2):
  arm: omap: sata: move enable sata clocks to enable_basic_clocks()
  drivers: block: dwc_ahci: Implement a driver for Synopsys DWC sata
    device
