Function Documentation

◆ sunxi_clk_dump()

void sunxi_clk_dump ( void )

Dump all clock-related register values.

This function prints out all clock-related register values for debugging and observation.

◆ sunxi_clk_init()

void sunxi_clk_init ( void )

Initialize the global clocks.

This function initializes the global clocks, including PLLs and clock dividers.

Initialize the global clocks.

This function configures various clock sources for the CPU, AXI, APB, NSI, and MBUS based on the Sunxi platform's requirements. The function also prints debug messages to track the initialization process.

It performs the following tasks:

Configures the CPU and AXI clock using the set_pll_cpux_axi() function.
Configures the APB clock using the set_apb() function.
Configures the NSI clock using the set_pll_nsi() function.
Configures the MBUS clock using the set_pll_mbus() function.

Note: This function should be called during the system initialization process to ensure the correct operation of the platform's clock system.

Warning: Ensure that all the clock configuration functions are correctly implemented and tested to avoid system instability.
