RK3399 (RockPro64) can't setup upstream opp tables

Recently I find that no matter what opp tables I'm using (default and
op1), the RockPro64 board always failed to add the opp table with the
following error messages:
[ 2.443667] rk3399-dmc-freq ffa80000.dmc: supply center not found,
using dummy regulator
[ 2.444366] dwmmc_rockchip fe310000.mmc: IDMAC supports 32-bit
[ 2.444527] rk3399-dmc-freq ffa80000.dmc: Invalid operating-points in
[ 2.445037] dwmmc_rockchip fe310000.mmc: Using internal DMA controller.
[ 2.445661] rk3399-dmc-freq: probe of ffa80000.dmc failed with error -22
I tried the default opp table (rk3399-opp.dts) and the op1, they both
failed with the same messages.
Upstream kernel v5.14.2 (With one commit reverted to address the
ethernet regression) and upstream v5.15-rc1 kernels both tested, no good
Is there some regression in rockchip related code that prevents the
default/op1 opp tables from getting applied properly?
