2012-05-12	SPEAr: clk: Add Auxiliary Synthesizer clock	Viresh Kumar	3	-1/+242
	All SPEAr SoC's contain Auxiliary Synthesizers. Their Fout is derived based on values of eq, x and y. Fout from synthesizer can be given from two equations: Fout1 = (Fin * X/Y)/2 EQ1 Fout2 = Fin * X/Y EQ2 This patch adds in support for this type of clock.

2012-05-12	SPEAr: clk: Add VCO-PLL Synthesizer clock	Viresh Kumar	4	-0/+462
	All SPEAr SoC's contain PLLs. Their Fout is derived based on following equations - In normal mode vco = (2 * M[15:8] * Fin)/N - In Dithered mode vco = (2 * M[15:0] * Fin)/(256 * N) pll_rate = vco/2^p vco and pll are very closely bound to each other, "vco needs to program: mode, m & n" and "pll needs to program p", both share common enable/disable logic and registers. This patch adds in support for this type of clock. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Reviewed-by: Mike Turquette <mturquette@linaro.org>
