2022-09-19drm/amd/display: rework recent update PHY state commitWenjing Liu1-0/+8
[why] Original change 594b237b9a07 ("drm/amd/display: Add interface to track PHY state") was implemented by assuming stream's dpms off is equivalent to PHY power off. This assumption doesn't hold in following situations: 1. MST multiple stream scenario, where multiple streams are sharing the same PHY output. Toggle dpms off for one of the stream doesn't power off the PHY due to the presence of other streams. 2. enable stream failure scenario, where enable stream fails due to failure of link training. This will cause DPMS off is set to false, while the actual PHY power state is off in certain cases. Due to the problematic assumption, the logic will skip disabling other streams for MST multiple stream scenario, therefore PHY is not actually powered off. [how] 1. Rework this refactor by moving PHY state update down to hardware level, where we update PHY state in place when hardware sequencer is actually changing the power state of the PHY hardware. 2. Reimplement symclk on TX off workaround in place when we are actually calling transmitter control to power off PHY in dcn32. Note the workaround is added due to the lack of proper software interface to set TX while keeping symclk on. We plan to address this interface problem so we can set TX off only without affecting symclk in future dcn versions.

2019-11-13drm/amd/display: set MSA MISC1 bit 6 while sending colorimetry in VSC SDPAnthony Koo1-0/+1
[Why] It is confusing to sinks if we send VSC SDP only on some format. Today we signal colorimetry format using MSA while in formats like sRGB. But when we switch to BT2020 we set the bit to ignore MSA colorimetry and instead use the colorimetry information in the VSC SDP. But if sink supports signaling of colorimetry via VSC SDP we should always set the MSA MISC1 bit 6, instead of doing so selectively. [How] If sink supports signaling of colorimetry via VSC SDP, and we are sending the colorimetry info via VSC SDP with packet revision 05h, then always set MSA MISC1 bit 6.

2017-10-21drm/amd/display: Move power control from link encoder to hwsequencerAndrew Jiang1-5/+0
A recent commit moved the backlight control code along with the register defines, but did not move the power control code. This along with remnant fields in the dce110_link_enc_registers struct made it so that the code still compiled, but any attempts to access the LVTMA_PWRSEQ_STATE register led to reading from an address of 0. This patch corrects that. Also, rename blacklight_control to edp_backlight_control (Typo fix).
