Return clock rate for specified PLL settings. | |
PLL configuration | |
static void | pll_config_init (struct pll_config *cfg, enum pll_source src, unsigned int div, unsigned int mul) |
Initialize PLL configuration from standard parameters. | |
static void | pll_config_read (struct pll_config *cfg, unsigned int pll_id) |
Read the currently active configuration of pll_id. | |
static void | pll_config_write (const struct pll_config *cfg, unsigned int pll_id) |
Activate the configuration cfg on pll_id. | |
Interaction with the PLL hardware | |
static void | pll_disable (unsigned int pll_id) |
Disable the PLL identified by pll_id. | |
static void | pll_enable (const struct pll_config *cfg, unsigned int pll_id) |
Activate the configuration cfg and enable PLL pll_id. | |
static bool | pll_is_locked (unsigned int pll_id) |
Determine whether the PLL is locked or not. |
