Current implementation of the libahci does not take into account the new PHY framework. Correct the situation by adding a call to phy_set_mode() before phy_power_on(). PHYs should also be handled at suspend/resume time. For this, call ahci_platform_enable/disable_phys() at suspend/resume_host() time. These calls are guarded by a HFLAG (AHCI_HFLAG_SUSPEND_PHYS) that the user of the libahci driver must set manually in hpriv->flags at probe time. This is to avoid breaking users that have not been tested with this change.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
