Function Documentation

void __init s3c64xx_register_clocks	(	unsigned long	xtal,
		unsigned	armclk_divlimit
	)

s3c64xx_register_clocks - register clocks for s3c6400 and s3c6410 : The rate for the clock crystal feeding the PLLs. : Divisor mask for ARMCLK.

Register the clocks for the S3C6400 and S3C6410 SoC range, such as ARMCLK as well as the necessary parent clocks.

This call does not setup the clocks, which is left to the s3c64xx_setup_clocks() call which may be needed by the cpufreq or resume code to re-set the clocks if the bootloader has changed them.
