This patch implements SKL DPLL programming that includes: - DPLL allocation - wide range PLL calculation and programming - DP link rate programming - DDI to DPLL mapping v2: Incorporated following changes - Added vfunc for function required outside - Fixed multiple comments in WRPLL calculation v3: - Fix the DCO computation - Move the initialization up to not clobber the computed values - Use the correct macro for DP link rate programming. - Use wait_for() to wait for the PLL locked bit v4: Rebase on top of nigthly (Damien) v5: A few code cleanups in the WRPLL computation (Damien) - Use uint32_t when possible - Use abs_diff() in the WRPLL computation - Make the 64bits divisions use div64_u64() - Fix typo in dco_central_feq_deviation (freq) - Replace the chain of breaks with a goto v6: Port of the patch to work on top of the shared DPLLs (Damien) v7: Don't try to handle eDP in ddi_pll_select() (Damien) v8: Modified as per review comments from Paulo (Satheesh) v9: Rebase on top of Ander's clock computation staging work for atomic (Damien) Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Satheeshakrishna M <satheeshakrishna.m@intel.com> (v3) Signed-off-by: Damien Lespiau <damien.lespiau@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
