I noticed that musb is blocking core retention for omap4 unlike for omap3. This is because for omap3 we have phy-twl4030-usb implement it's own PM runtime to handle errata "VUSB3V1 VBUS overvoltage debouncer not working when the PHY is powered down". That is done in order to keep the USB PHY powered when phy-twl4030-usb is loaded. For the other USB PHYs, we need to enable and disable the PHY based on musb PM runtime. With the session bit based PM runtime for musb core, we can now idle the USB PHY always when musb is idle. Note that adding these calls will not affect the twl4030 driver as it's phy functions will just query the PHY state without powering the PHY on or off.

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.
