- Update maintainer; Nicolas hasn't been active and it makes more sense to have a Broadcom maintainer - Add a driver compatible string for the new STB SOC 7712 - Add two new resets for the 7712: "bridge", for the the bridge between the PCIe core and the memory bus; "swinit", the PCIe core reset. - Order the compatible strings alphabetically - Restructure the reset controllers so that the definitions appear first before any rules that govern them.
