System Firmware

Cortex-M3 (CM3) firmware for power management The IP does not require this clock, it can be disabled, regardless of the state of the device

TISCI_MSG_VALUE_CLOCK_SW_STATE_AUTO

#define TISCI_MSG_VALUE_CLOCK_SW_STATE_AUTO   1

Allow the system controller to automatically manage the state of this clock. If the device is enabled, then the clock is enabled. If the device is set to off or retention, then the clock is internally set as not being required by the device. This is the default state.

TISCI_MSG_VALUE_CLOCK_SW_STATE_REQ

#define TISCI_MSG_VALUE_CLOCK_SW_STATE_REQ   2

Configure the clock to be enabled, regardless of the state of the device.

TISCI_MSG_VALUE_CLOCK_HW_STATE_NOT_READY

#define TISCI_MSG_VALUE_CLOCK_HW_STATE_NOT_READY   0

Indicate hardware state of the clock is that it is not running.

TISCI_MSG_VALUE_CLOCK_HW_STATE_READY

#define TISCI_MSG_VALUE_CLOCK_HW_STATE_READY   1

Indicate hardware state of the clock is that it is running.

TISCI_MSG_FLAG_CLOCK_ALLOW_SSC

#define TISCI_MSG_FLAG_CLOCK_ALLOW_SSC   TISCI_BIT(8)

Allow this clock to be modified via spread spectrum clocking.

Note

: The SSC feature is currently not supported in System Firmware.

TISCI_MSG_FLAG_CLOCK_ALLOW_FREQ_CHANGE

#define TISCI_MSG_FLAG_CLOCK_ALLOW_FREQ_CHANGE   TISCI_BIT(9)

Allow this clock's frequency to be changed while it is running so long as it is within the min/max limits.

TISCI_MSG_FLAG_CLOCK_INPUT_TERM

#define TISCI_MSG_FLAG_CLOCK_INPUT_TERM   TISCI_BIT(10)

Enable input termination, this is only applicable to clock inputs on the SoC pseudo-device, TISCI_BOARD0.

TISCI_MSG_FLAG_CLOCK_SSC_ACTIVE

#define TISCI_MSG_FLAG_CLOCK_SSC_ACTIVE   TISCI_BIT(11)

Indicate that SSC is active for this clock.

Note

: The SSC feature is currently not supported in System Firmware.
