In order to remove intel_atomic_crtc_state_for_each_plane_state() from skl_crtc_can_enable_sagv() we can simply precompute whether each wm level can tolerate the SAGV block time latency or not. This has the nice side benefit that we remove the duplicated wm level latency calculation. In fact the copy of that code we had in skl_crtc_can_enable_sagv() didn't even handle WaIncreaseLatencyIPCEnabled/Display WA #1141 whereas the copy in skl_compute_plane_wm() did. So now we just have the one copy which handles all the w/as. Signed-off-by:

intel_atomic_crtc_state_for_each_plane_state() peeks at the plane's current state without holding the plane's mutex, trusting that the crtc's mutex will protect it. In practice that does work since our planes can't move between pipes, but it sets a bad example. intel_atomic_crtc_state_for_each_plane_state() also relies on crtc_state.uapi.plane_mask which may be full of lies when it comes to the bigjoiner stuff, so soon we can't use it as is anyway. So best to just get rid of it entirely. Which we can easily do by switching to the g4x/vlv "raw" watermark approach. Later on we should even be able to move the "raw" watermark computation into the normal .plane_check() code, leaving only the merging/clamping of the final watermarks to the later stages. But that will require adjusting the ilk+ wm code similarly as well. Signed-off-by:

No reason to make the callers of intel_crtc_get_pipe_config() populate hw.active. Let's do it in intel_crtc_get_pipe_config() itself. hw.enable we leave up to the callers since it's slightly different for readout vs. state check. Signed-off-by:

DG1 uses 2 registers for the ddi clock mapping, with PHY A and B using DPCLKA_CFGCR0 and PHY C and D using DPCLKA1_CFGCR0. Hide this behind a single macro that chooses the correct register according to the phy being accessed, use the correct bitfields for each pll/phy and implement separate functions for DG1 since it doesn't share much with ICL/TGL anymore. The previous values were correct for PHY A and B since they were using the same register as before and the bitfields were matching. v2: Add comment and try to simplify DG1_DPCLKA* macros by reusing previous ones v3: - Fix DG1_DPCLKA_CFGCR0_DDI_CLK_SEL_MASK() after wrong macro reuse - Move phy -> id map to a separate macro (Aditya) - Remove DG1_DPCLKA_CFGCR0_DDI_CLK_SEL_MASK where not required (Aditya) - Use drm_WARN_ON Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Clinton Taylor <Clinton.A.Taylor@intel.com> Cc: Matt Roper <matthew.d.roper@intel.com> Cc: Aditya Swarup <aditya.swarup@intel.com> Signed-off-by:
