[PATCH 2/6] dt-bindings: eeprom: at25: explicitly list SPI CPHA and CPOL
From: Krzysztof Kozlowski <hidden>
Date: 2022-07-21 15:32:36

Subsystem:
open firmware and flattened device tree bindings, the rest · Maintainers:
Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
The spi-cpha and spi-cpol properties are device specific and should be accepted only if device really needs them. Explicitly list them in device bindings in preparation of their removal from generic spi-peripheral-props.yaml schema.
