109 int "Kernel HZ (jiffies per second)"
112 default "128" if SOC_AT91RM9200
115 On AT91rm9200 chips where you're using a system clock derived
116 from the 32768 Hz hardware clock, this tick rate should divide
117 it exactly: use a power-of-two value, such as 128 or 256, to
118 reduce timing errors caused by rounding.
120 On AT91sam926x chips, or otherwise when using a higher precision
121 system clock (of at least several MHz), rounding is less of a
122 problem so it can be safer to use a decimal values like 100.
