* drm/amd/display: Connect dig_fe to otg directly instead of calling bioshersen wu2019-01-251-116/+0
| | | | | | | | | | | | | [Why] After call bios table crtc_source_select, dal will program fmt again. The bios table program dig_source_select and other fmt register for bios usage which is redundancy and uncessary. [How] Program dig_soruce_select register directly Signed-off-by: hersen wu <hersenxs.wu@amd.com> Reviewed-by: Charlene Liu <Charlene.Liu@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* drm/amd/display: Use 100 Hz precision for pipe pixel clocksKen Chalmers2019-01-141-10/+9
| | | | | | | | | | | | | | | [Why] Users would like more accurate pixel clocks, especially for fractional "TV" frame rates like 59.94 Hz. [How] Store and communicate pixel clocks with 100 Hz accuracy from dc_crtc_timing through to BIOS command table setpixelclock call.

* drm/amd/display: Set DFS bypass flags for dce110Nicholas Kazlauskas2018-08-271-0/+3
| | | | | | | | | | | | | | | | | | | [Why] While there is support for using and quering DFS bypass clocks the hardware is never notified to enter DFS bypass mode for dce110. [How] Add a flag that can be set when programming the display engine PLL to enable DFS bypass mode. If this flag is set then the hardware is notified to enter DFS bypass mode and the correct display engine clock frequency can be acquired.

* drm/amd/display: update clk for various HDMI color depthsMikita Lipski2018-08-061-0/+18
| | | | | | | | | | | | | | | | | | [why] When programming tonga's connector's backend we didn't take in account that HDMI's colour depth might be more than 8bpc therefore we need to add a switch statement that would adjust the pixel clock accordingly. [how] Add a switch statement updating clock by its appropriate coefficient.

| | | | | | | | | | I assumed wrongfully that all relevant functions should be implemented. Apparently this isn't the case. Demote the print to debug level for now.

* drm/amd/display: Error print when ATOM BIOS implementation is missingHarry Wentland2017-12-201-0/+21
| | | | | | | | | | | | | | | | We fail apply_ctx_to_hw when crtc_source_select is missing. This isn't really helpful at this point. It would aid ASIC bringup if we log an error when we can't find the implementation for the ATOM version. Do the same for all other function points in the command table that do a NULL check before being called.
