Hi All,
On my rock960 I want to add power domain feature for pcie node using
following patch. [0] https://patchwork.kernel.org/patch/9322549/
I also tried to add some more cru to see below
but the power domain summary shows unsupported
# cat /sys/kernel/debug/pm_genpd/pm_genpd_summary
...
pd_sdioaudio off-0
/devices/platform/fe310000.dwmmc suspended
/devices/platform/ff8a0000.i2s suspended
pd_perihp on
/devices/platform/fe380000.usb unsupported
/devices/platform/fe3c0000.usb unsupported
/devices/platform/fe3a0000.usb suspended
/devices/platform/fe3e0000.usb suspended
/devices/platform/f8000000.pcie unsupported
pd_sd on
/devices/platform/fe320000.dwmmc active
pd_gmac off-0
...
can any one share more inputs.
