commit 33c7dca3f212ef8dff75312e1e4044fb1bcae898
Author: James Simmons <jsimmons@infradead.org>
Date:   Sat Jun 8 09:24:11 2013 -0400

    via: Display register tables and engine register definitions
    
    The via_disp_reg.h contains tables that define the registers
    and their bit fields we need for various resolution settings
    or property handing (i.e scaling). The second header via_regs.h
    contains convient names for registers relating to the graphic
    engines. We also update the command verifier to handle these
    changes. More 3D register definitions are added to via_3d_reg.h.
