| * dt-bindings: i3c: drop "master" node name suffixKrzysztof Kozlowski2024-02-186-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drop the requirement of "-master" suffix in node names because: 1. "Master" word is discouraged and MIPI Alliance renamed it to "Controller". 2. Some devices can operate in Controller (Master) or Target mode, thus the name is not accurate in such cases. 3. Other buses, like I2C controllers, use simple "i2c".
