Sorry, I was misled by the dtsi of rk3568. Put it in reserved-memory works on rk3528: ~# dmesg | grep scmi [ 0.061452] scmi_core: SCMI protocol bus registered [ 0.125903] scmi_protocol scmi_dev.1: Enabled polling mode TX channel - prot_id:16 [ 0.126763] arm-scmi firmware:scmi: SCMI Notifications - Core Enabled. [ 0.127368] arm-scmi firmware:scmi: SCMI Protocol v2.0 'rockchip:' Firmware version 0x0 Should we change this for rk3568 as well? Thanks, Chukun -- 2.25.1
