Messages in this thread Patch in this message | | | From | Dan Murphy <> | Subject | [PATCH net-next v3 1/2] dt-bindings: dp83867: Convert fifo-depth to common fifo-depth and make optional | Date | Mon, 9 Dec 2019 14:10:24 -0600 |
| |
Convert the ti,fifo-depth from a TI specific property to the common tx-fifo-depth property. Also add support for the rx-fifo-depth.
These are optional properties for this device and if these are not available then the fifo depths are set to device default values.

v3 - No changes v2 - Rebase on linux-net next as the patch would not apply
