TI keystone display subsystem present in AM65 and other SoCs such as AM62 support two separate register spaces namely "common" and "common1" which can be used by two separate hosts to program the display controller as described in respective Technical Reference Manuals [1]. The common1 register space has similar set of configuration registers as supported in common register space except the global configuration registers which are exclusive to common region. This adds binding for "common1" register region too as supported by the hardware.
