Override enable bits may not be restored when going to low power mode (e.g. when in DWC2_POWER_DOWN_PARAM_NONE). These bits are set when probing/initializing drd (role switch). Restore them upon resume from low power mode (in case these have been lost). To achieve this, the last known role is restored upon resume. And the override enable bits are always set when configuring aval, bval and vbval. When resuming, forcing the role should be done only once, or this can cause port changes in HOST mode for instance. So, only restore FORCEDEVMODE/FORCEHOSTMODE when role_sw is unused Acked-by: Minas Harutyunyan <Minas.Harutyunyan@synopsys.com> Signed-off-by: Fabrice Gasnier <fabrice.gasnier@foss.st.com> Link: https://lore.kernel.org/r/1638806203-6624-4-git-send-email-fabrice.gasnier@foss.st.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

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.
