| Description: This read-write attribute allows userspace to trigger a |
| Product Level Device Reset (PLDR) on Intel PCIe Bluetooth |
| controllers. Reading the attribute displays the supported |
| reset type. Writing integer 0 triggers PLDR. Any other |
| input is rejected with -EINVAL. |
| |
| PLDR resets the entire on-chip platform shared between |
| Bluetooth and WiFi. This means any driver attached to |
| the WiFi device that shares hardware with this Bluetooth |
| device will be released, the platform will be reset, and |
| both the Bluetooth and WiFi devices will be re-probed. |
