Device Tables (DT) for IP pwm and top earlgrey.
This file contains the type definitions and global functions of the pwm.

| #define OPENTITAN_PWM_HAS_DUTYCYCLE 1 |
| typedef enum dt_pwm_alert dt_pwm_alert_t |
List of Alerts.
Alerts are guaranteed to be numbered consecutively from 0.
| typedef enum dt_pwm_clock dt_pwm_clock_t |
List of clock ports.
Clock ports are guaranteed to be numbered consecutively from 0.
| typedef enum dt_pwm_periph_io dt_pwm_periph_io_t |
List of peripheral I/O.
Peripheral I/O are guaranteed to be numbered consecutively from 0.
| typedef enum dt_pwm_reg_block dt_pwm_reg_block_t |
List of register blocks.
Register blocks are guaranteed to start at 0 and to be consecutively numbered.
| typedef enum dt_pwm_reset dt_pwm_reset_t |
List of reset ports.
Reset ports are guaranteed to be numbered consecutively from 0.

| enum dt_pwm_reset |
| dt_pwm_alert_t dt_pwm_alert_from_alert_id | ( | dt_pwm_t | dt, |
| dt_alert_id_t | alert ) |
Convert a global alert ID to a local pwm alert type.
| dt | Instance of pwm. |
| alert | A global alert ID that belongs to this instance. |
kDtPwmAlertCount.Note: This function assumes that the global alert ID belongs to the instance of pwm passed in parameter. In other words, it must be the case that dt_pwm_instance_id(dt) == dt_alert_id_to_instance_id(alert). Otherwise, this function will return kDtPwmAlertCount.
| dt_alert_id_t dt_pwm_alert_to_alert_id | ( | dt_pwm_t | dt, |
| dt_pwm_alert_t | alert ) |
Get the alert ID of a pwm alert for a given instance.
Note: This function only makes sense if the instance is connected to the Alert Handler. For any instances where the instance is not connected, the return value is unspecified.
| dt | Instance of pwm. |
| alert | A pwm alert. |
| dt_clock_t dt_pwm_clock | ( | dt_pwm_t | dt, |
| dt_pwm_clock_t | clk ) |
| dt_pwm_t dt_pwm_from_instance_id | ( | dt_instance_id_t | inst_id | ) |
Get the pwm instance from an instance ID.
For example, dt_uart_from_instance_id(kDtInstanceIdUart3) == kDtUart3.
| inst_id | Instance ID. |
Note: This function only makes sense if the instance ID has device type pwm, otherwise the returned value is unspecified.
