| * NOTE: |
| * 1. The DTS file only support i.MX8MQ EVK RevB1/B2 board PCIe M.2 Murata |
| * 1CQ (Qca6174) WIFI & BT. |
| * EVK RevB1 rework: |
| * WIFI rework: fly line from R1436 (near to M.2) to R1459 |
| * BT rework: ensure R1446,R1447,R1448,R1449 installed on board |
| * EVK RevB2 rework: no rework |
| * |
| * 2. If need to support i.MX8MQ EVK RevA0/A1 board PCIe M.2 Murata 1CQ |
| * (Qca6174) WIFI & BT, some board rework requirement: |
| * EVK RevA0 rework: |
| * WIFI rework: install R1436 for wlreg_on |
| * EVK RevA0 rework: |
| * WIFI rework: install R1436 for wlreg_on |
| * BT rework: fly line from M.2 pin54 to R1437 |
