     title: Clock bindings for Freescale i.MX7ULP System Clock Generation (SCG) modules

      i.MX7ULP Clock functions are under joint control of the System
      Clock Generation (SCG) modules, Peripheral Clock Control (PCC)
      modules, and Core Mode Controller (CMC)1 blocks
    
      The clocking scheme provides clear separation between M4 domain
      and A7 domain. Except for a few clock sources shared between two
      domains, such as the System Oscillator clock, the Slow IRC (SIRC),
      and and the Fast IRC clock (FIRCLK), clock sources and clock
      management are separated and contained within each domain.
    
      M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.
      A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.
    
      Note: this binding doc is only for A7 clock domain.
    
      The System Clock Generation (SCG) is responsible for clock generation
      and distribution across this device. Functions performed by the SCG
      include: clock reference selection, generation of clock used to derive
      processor, system, peripheral bus and external memory interface clocks,
      source selection for peripheral clocks and control of power saving
      clock gating mode.
    
      The clock consumer should specify the desired clock by having the clock
      ID in its "clocks" phandle cell.
      See include/dt-bindings/clock/imx7ulp-clock.h for the full list of
      i.MX7ULP clock IDs of each module.
