+ * Flags used across common struct clk. These flags should only affect the

*
- * Please update clk_flags[] in drivers/clk/clk.c when making changes here!
+ * * CLK_SET_RATE_GATE - must be gated across rate change
+ * * CLK_SET_PARENT_GATE - must be gated across re-parent
+ * * CLK_SET_RATE_PARENT - propagate rate change up one level
+ * * CLK_IGNORE_UNUSED - do not gate even if unused
+ * * CLK_GET_RATE_NOCACHE - do not use the cached clk rate
+ * * CLK_SET_RATE_NO_REPARENT - don't re-parent on rate change
+ * * CLK_GET_ACCURACY_NOCACHE - do not use the cached clk accuracy
+ * * CLK_RECALC_NEW_RATES - recalc rates after notifications
+ * * CLK_SET_RATE_UNGATE - clock needs to run to set rate
+ * * CLK_IS_CRITICAL - do not gate, ever
+ * * CLK_OPS_PARENT_ENABLE - parents need enable during gate/ungate, set rate and re-parent
+ * * CLK_DUTY_CYCLE_PARENT - duty cycle call may be forwarded to the parent clock
