First of all the DW uMCTL2 DDRC IP-core supports the individual IRQ lines for each standard event: ECC Corrected Error, ECC Uncorrected Error, ECC Address Protection, Scrubber-Done signal, DFI Parity/CRC Error. It's possible that the platform engineers merge them up in the IRQ controller level. So let's add both configuration support to the DT-schema. Secondly the DW uMCTL2 DDRC IP-core can have clock sources like APB reference clock, AXI-ports clock, main DDRC core reference clock and Scrubber low-power clock. In addition to that each clock domain can have a dedicated reset signal. Let's add the properties for at least the denoted clock sources and the corresponding reset controls. Note the IRQs and the phandles order is deliberately not fixed since some of the sources may be absent depending on the IP-core synthesize parameters and the particular platform setups.

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.
