419 * CpuCP Primary Queue Packets
420 *
421 * During normal operation, the host's kernel driver needs to send various
422 * messages to CpuCP, usually either to SET some value into a H/W periphery or
423 * to GET the current value of some H/W periphery. For example, SET the
424 * frequency of MME/TPC and GET the value of the thermal sensor.
425 *
426 * These messages can be initiated either by the User application or by the
427 * host's driver itself, e.g. power management code. In either case, the
428 * communication from the host's driver to CpuCP will *always* be in
429 * synchronous mode, meaning that the host will send a single message and poll
430 * until the message was acknowledged and the results are ready (if results are
431 * needed).
432 *
433 * This means that only a single message can be sent at a time and the host's
434 * driver must wait for its result before sending the next message. Having said
435 * that, because these are control messages which are sent in a relatively low
436 * frequency, this limitation seems acceptable. It's important to note that
437 * in case of multiple devices, messages to different devices *can* be sent
438 * at the same time.
439 *
440 * The message, inputs/outputs (if relevant) and fence object will be located
441 * on the device DDR at an address that will be determined by the host's driver.
442 * During device initialization phase, the host will pass to CpuCP that address.
443 * Most of the message types will contain inputs/outputs inside the message
444 * itself. The common part of each message will contain the opcode of the
445 * message (its type) and a field representing a fence object.
446 *
447 * When the host's driver wishes to send a message to CPU CP, it will write the
448 * message contents to the device DDR, clear the fence object and then write to
449 * the PSOC_ARC1_AUX_SW_INTR, to issue interrupt 121 to ARC Management CPU.
450 *
451 * Upon receiving the interrupt (#121), CpuCP will read the message from the
452 * DDR. In case the message is a SET operation, CpuCP will first perform the
453 * operation and then write to the fence object on the device DDR. In case the
454 * message is a GET operation, CpuCP will first fill the results section on the
455 * device DDR and then write to the fence object. If an error occurred, CpuCP
456 * will fill the rc field with the right error code.
457 *
458 * In the meantime, the host's driver will poll on the fence object. Once the
459 * host sees that the fence object is signaled, it will read the results from
460 * the device DDR (if relevant) and resume the code execution in the host's
461 * driver.
462 *
463 * To use QMAN packets, the opcode must be the QMAN opcode, shifted by 8
464 * so the value being put by the host's driver matches the value read by CpuCP
465 *
466 * Non-QMAN packets should be limited to values 1 through (2^8 - 1)
467 *
468 * Detailed description:
469 *
470 * CPUCP_PACKET_DISABLE_PCI_ACCESS -
471 * After receiving this packet the embedded CPU must NOT issue PCI
472 * transactions (read/write) towards the Host CPU. This also include
473 * sending MSI-X interrupts.
474 * This packet is usually sent before the device is moved to D3Hot state.
475 *
476 * CPUCP_PACKET_ENABLE_PCI_ACCESS -
477 * After receiving this packet the embedded CPU is allowed to issue PCI
478 * transactions towards the Host CPU, including sending MSI-X interrupts.
479 * This packet is usually send after the device is moved to D0 state.
480 *
481 * CPUCP_PACKET_TEMPERATURE_GET -
482 * Fetch the current temperature / Max / Max Hyst / Critical /
483 * Critical Hyst of a specified thermal sensor. The packet's
484 * arguments specify the desired sensor and the field to get.
485 *
486 * CPUCP_PACKET_VOLTAGE_GET -
487 * Fetch the voltage / Max / Min of a specified sensor. The packet's
488 * arguments specify the sensor and type.
489 *
490 * CPUCP_PACKET_CURRENT_GET -
491 * Fetch the current / Max / Min of a specified sensor. The packet's
492 * arguments specify the sensor and type.
493 *
494 * CPUCP_PACKET_FAN_SPEED_GET -
495 * Fetch the speed / Max / Min of a specified fan. The packet's
496 * arguments specify the sensor and type.
497 *
498 * CPUCP_PACKET_PWM_GET -
499 * Fetch the pwm value / mode of a specified pwm. The packet's
500 * arguments specify the sensor and type.
501 *
502 * CPUCP_PACKET_PWM_SET -
503 * Set the pwm value / mode of a specified pwm. The packet's
504 * arguments specify the sensor, type and value.
505 *
506 * CPUCP_PACKET_FREQUENCY_SET -
507 * Set the frequency of a specified PLL. The packet's arguments specify
508 * the PLL and the desired frequency. The actual frequency in the device
509 * might differ from the requested frequency.
510 *
511 * CPUCP_PACKET_FREQUENCY_GET -
512 * Fetch the frequency of a specified PLL. The packet's arguments specify
513 * the PLL.
