Find that ring sdma0 test failed if turn on SDMA powergating after do mode2 reset. Perhaps the mode2 reset does not reset the SDMA PG state, SDMA is already powered up so there is no need to ask the SMU to power it up again. So I skip this function for a moment. Signed-off-by:

Polaris and vegam use count for the value rather than level. This looks like a copy paste typo from when the code was adapted from previous asics. I'm not sure that the SMU actually uses this value, so I don't know that it actually is a bug per se. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=108609 Reported-by:

[Why] HDMI 2.0 requires scrambling under specific conditions. We refer to stream property LTE_340MCSC_SCRAMBLE to determine whether en/dis scrambling. While creating stream for sink, we setup LTE_340MCSC_SCRAMBLE by referring to edid_caps. However, dm_helpers_parse_edid_caps() doesn't construct HDMI Forum block data for edid_caps. Moreover, fill_stream_properties_from_drm_display_mode() aslo unconsciously clear the LTE_340MCSC_SCRAMBLE flag. [How] Drm already provides drm_display_info to refer HDMI Forum vsdb info.

Otherwise, it is not cleared, and stale information remains. During mode validation: function: dp_active_dongle_validate_timing reads link->dpcd_caps.dongle_caps->dongle_type to determine the maximum pixel clock to support. This information is now stale and no longer valid. [HOW] dp_active_dongle_validate_timing should be using link->dpcd_caps->dongle_type instead. Signed-off-by:
