Subject: [PATCH v1] dt-bindings: spi: rockchip: add power-domains property
Date: Sat, 10 Sep 2022 20:56:28 +0200 [thread overview]
Message-ID: <64d03f6e-c578-3155-e3fb-53dbe53573eb@gmail.com> (raw)
The Rockchip rk3399 TRM mentions that pd_sdioaudio includes
sdio, spi, i2s and spdif. Add a power-domains property to
reduce notifications with spi-rockchip.yaml.
