* drm/i915: Move intel_ddi_fdi_post_disable() to fdi codeVille Syrjälä2021-10-191-0/+1
| | | | | | | | | | | | | | | | | | | Reanme intel_ddi_fdi_post_disable() to hsw_fdi_disable() and relocate it next to all the other code dealing with FDI_RX. intel_ddi.c has now been cleansed of FDI_RX. In order to avoid exposing intel_disable_ddi_buf() outside intel_ddi.c we can just open code the DDI_BUF_CTL write. The enable side already has all that stuff open coded so this actually is more symmetric. But we do need to remeber to bring the intel_wait_ddi_buf_idle() call over from inside intel_disable_ddi_buf().

* drm/i915: Move PCH refclock stuff into its own fileVille Syrjälä2021-10-191-1/+0
| | | | | | | | | | | | | | Move the PCH refclk stuff (including all the LPT/WPT iCLKIP/CLKOUT_DP things) to its own file. We also suck in the mPHY programming from intel_fdi.c since we're the only caller.

| | | | | | | | | This fairly detailed stuff that really has no place in intel_display.c. Combine the calls into one to avoid exposing both.

| | | | | | | | | | Accept slight duplication in the fdi link train hooks in exchange for simplification in ilk_pch_enable(). This lets us make ivb_update_fdi_bc_bifurcation() static again, now in intel_fdi.c.
