This series adds support for SATA using the driver model on omap platforms. It is based on the work of Mugunthan V N mugunthanvnm@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.
