- For CPG core clocks, the two clock specifier cells must be "CPG_CORE"
and a core clock reference, as defined in
- <dt-bindings/clock/renesas,r9a09g057-cpg.h>,
+ <dt-bindings/clock/renesas,r9a09g0*-cpg.h>,
- For module clocks, the two clock specifier cells must be "CPG_MOD" and
a module number. The module number is calculated as the CLKON register
offset index multiplied by 16, plus the actual bit in the register
