 542 * @AMD_RESET_METHOD_NONE: The device will not be reset.

 544 * @AMD_RESET_MODE0: Reset the entire ASIC. Not currently available for the
 545 *                   any device.
 546 * @AMD_RESET_MODE1: Resets all IP blocks on the ASIC (SDMA, GFX, VCN, etc.)
 547 *                   individually. Suitable only for some discrete GPU, not
 548 *                   available for all ASICs.
 549 * @AMD_RESET_MODE2: Resets a lesser level of IPs compared to MODE1. Which IPs
 550 *                   are reset depends on the ASIC. Notably doesn't reset IPs
 551 *                   shared with the CPU on APUs or the memory controllers (so
 552 *                   VRAM is not lost). Not available on all ASICs.
 553 * @AMD_RESET_BACO: BACO (Bus Alive, Chip Off) method powers off and on the card
 554 *                  but without powering off the PCI bus. Suitable only for
 555 *                  discrete GPUs.
 556 * @AMD_RESET_PCI: Does a full bus reset using core Linux subsystem PCI reset
 557 *                 and does a secondary bus reset or FLR, depending on what the
 558 *                 underlying hardware supports.
 559 *
