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
