The A20 has 2 clock outputs, CLK_OUT_A and CLK_OUT_B. The outputs are muxed on PI13 and PI14. The clocks have configurable dividers, and can be sourced from osc24M or osc32k. See page 92 of the A20's user manual. There's already a clk driver for them in mainline. And they are defined in the DTSI as well. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
