| # This allows encoding the entire BFP block in devicetree to avoid |
| # reading at runtime, while still allowing the driver to pull out extra |
| # data of interest, such as erase sizes. |
| # |
| # Alternatively the BFP block can be absent, but critical fields like |
| # size can be provided directly along with the JEDEC ID of the expected |
| # device to verify its presence at runtime. |
| # |
| # Only properties supported by parameter tables documented in the |
| # JESD216 standards should be listed in this binding include file. |

| Use NONE if the device detects 1-1-4 and 1-4-4 modes by the |
| instruction. Use S1B6 if QE is bit 6 of the first status register |
| byte, and can be configured by reading then writing one byte with |
| RDSR and WRSR. For other fields see the specification. |
