All Aspeed SoC clocks are driven by an input source clock which can have different frequencies : 24MHz or 25MHz, and also, on the Aspeed AST2400 SoC, 48MHz. The H-PLL (CPU) clock is defined from a calculation using parameters in the H-PLL Parameter register or from a predefined set of frequencies if the setting is strapped by hardware (Aspeed AST2400 SoC). The other clocks of the SoC are then defined from the H-PLL using dividers. We introduce first the APB clock because it should be used to drive the Aspeed timer model.
