Commit2a26d31b1b("ARM: OMAP2+: Remove unused legacy code for PRM") removed PRM platform init code that I thought is unused. Turns out omap4 still needs this code, so let's do a partial revert to add it back. I probably missed this earlier as the comments used to say "OMAP4+ is DT only now" for !of_have_populated_dt() to exit early and missed the negative test. Let's not add those lines back as they are confusing and no longer needed as we only boot in device tree mode. Without things things can mysterious fail for i2c, for example LM75 I2C temperature sensor can stop working as the PRM interrupts won't work.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
