NXP SoCs like the iMX8QM, iMX8QXP or iMX8DXP use power domains for resource management. Allow specifying them for such SoCs. Signed-off-by: John Ernberg <redacted> --- v3: - Fix warnings discovered by Rob Herring's bot - Declare the compatibles correctly (Krzysztof Kozlowski) v2: - Adjust commit message (Frank Li) - Only allow power-domains when compatible with imx8qm (Frank Li) --- .../bindings/crypto/fsl,sec-v4.0.yaml | 45 ++++++++++++++++++- 1 file changed, 44 insertions(+), 1 deletion(-)
