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