Those CMU units are modeled as separate device + tree nodes, and might depend on each other. Root clocks in that clock tree are + two external clocks:: OSCCLK/XTCXO (38.4 MHz) and RTCCLK/XrtcXTI (32768 Hz). + The external OSCCLK must be defined as fixed-rate clock in dts. + + CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and + dividers; all other clocks of function blocks (other CMUs) are usually + derived from CMU_TOP. + + Each clock is assigned an identifier and client nodes can use this identifier + to specify the clock which they consume. All clocks available for usage + in clock consumer nodes are defined as preprocessor macros in + 'include/dt-bindings/clock/samsung,exynosautov920.h' header. + +properties: + compatible: + enum: + -
