clk: st: Support for A9 MUX clocks
The patch supports the A9-mux clocks used by ClockGenA9 A9-mux clock : Multiplexer inside ClockGenA9. A9 clock can be driven by either PLL or External clock (with an optional divide-by-2). This is implemented as 3-parent clock : PLL, Ext-clk OR Ext-clk/2 Signed-off-by: Pankaj Dev <pankaj.dev@st.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
