	help
	  Allows the configuration of the timer frequency. It is customary
	  to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
	  case of low timer frequencies other values may be more suitable.
	  SH-Mobile systems using a 32768 Hz RCLK for clock events may want
	  to select a HZ value such as 128 that can evenly divide RCLK.
	  A HZ value that does not divide evenly may cause timer drift.

config SH_TIMER_CMT
	bool "CMT timer driver"
	default y
	help
	  This enables build of the CMT timer driver.
