clk: basic clock hardware types Many platforms support simple gateable clocks, fixed-rate clocks, adjustable divider clocks and multi-parent multiplexer clocks. This patch introduces basic clock types for the above-mentioned hardware which share some common characteristics. Based on original work by Jeremy Kerr and contribution by Jamie Iles. Dividers and multiplexor clocks originally contributed by Richard Zhao & Sascha Hauer.

clk: add a fixed factor clock Having fixed factors/dividers in hardware is a common pattern, so add a basic clock type doing this. It basically describes a fixed factor clock using a nominator and a denominator.

SPEAr: clk: Add VCO-PLL Synthesizer clock 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.
