Re: [PATCH] sh-sci: fix SCBRR value calculation

Please don't omit that term, that is for "round to near" operation.

round_to_near(clk/(32*bps)) -1
--> round_to_zero(clk/(32*bps) + 0.5) -1
--> (int)((clk+16*bps)/(32*bps)) -1

> -		return (clk+16*bps)/(32*bps)-1;

Former one is correct.

> -		return ((clk*2)+16*bps)/(16*bps)-1;
> +		return ((clk*2)/(16*bps)) - 1;
Both incorrect? Perhaps,
		return ((clk*2)+8*bps)/(16*bps) - 1;

I don't have read 7723 HW manual, though.
