   1 Binding for Texas Instruments interface clock.
   2
   3 This binding uses the common clock binding[1]. This clock is
   4 quite much similar to the basic gate-clock [2], however,
   5 it supports a number of additional features, including
   6 companion clock finding (match corresponding functional gate
   7 clock) and hardware autoidle enable / disable.
