Clock framework on SuperH architecture



The framework on SH extends existing API by the function clk_set_rate_ex,

which prototype is as follows:



    clk_set_rate_ex (struct clk *clk, unsigned long rate, int algo_id)



The algo_id parameter is used to specify algorithm used to recalculate clocks,

adjanced to clock, specified as first argument. It is assumed that algo_id==0

means no changes to adjanced clock



Internally, the clk_set_rate_ex forwards request to clk->ops->set_rate method,

if it is present in ops structure. The method should set the clock rate and adjust

all needed clocks according to the passed algo_id.

Exact values for algo_id are machine-dependend. For the sh7722, the following

values are defined:



	NO_CHANGE	= 0,

	IUS_N1_N1,	/* I:U = N:1, U:Sh = N:1 */

	IUS_322,	/* I:U:Sh = 3:2:2	 */

	IUS_522,	/* I:U:Sh = 5:2:2 	 */

	IUS_N11,	/* I:U:Sh = N:1:1	 */

	SB_N1,		/* Sh:B = N:1		 */

	SB3_N1,		/* Sh:B3 = N:1		 */

	SB3_32,		/* Sh:B3 = 3:2		 */

	SB3_43,		/* Sh:B3 = 4:3		 */

	SB3_54,		/* Sh:B3 = 5:4		 */

	BP_N1,		/* B:P	 = N:1		 */

	IP_N1		/* I:P	 = N:1		 */



Each of these constants means relation between clocks that can be set via the FRQCR

register
