drm/i915: Add correct hw/sw config check for DSI encoder
Check in vlv_crtc_clock_get if DPLL is enabled before calling dpio read. It will not be enabled for DSI and avoid dpio read WARN dumps. Absence of ->get_config was causing other WARN dumps as well. Update dpll_hw_state as well correctly v2: Address review comments by Daniel - Check if DPLL is enabled rather than checking pipe output type - set adjusted_mode->flags to 0 in compute_config rather than using pipe_config->quirks - Add helper function in intel_dsi_pll.c and use that in intel_dsi.c - updated dpll_hw_state correctly - Updated commit message and title v3: Address review comments by Imre - Proper masking of P1, M1 fields while computing divisors - assert in case of bpp mismatch - guard for divide by 0 while computing pclk - Use ARRAY_SIZE instead of direct calculation Signed-off-by: Shobhit Kumar <shobhit.kumar@intel.com> Reviewed-by: Imre Deak <imre.deak@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
