void ilk_pch_enable(struct intel_atomic_state *state,
struct intel_crtc *crtc);
drm/i915: Introduce ilk_pch_disable() and ilk_pch_post_disable() Hoover the remaining open coded PCH modeset sequence bits out from ilk_crtc_disable(). Somewhat annoyingly the enable vs. disable is a bit asymmetric so we need two functions for the disable case.

drm/i915: Extract ilk_pch_get_config() Pull the ilk+ PCH state readout into its own function and relocate to the appropriate file. The clock readout parts are perhaps a bit iffy since we depend on the gmch DPLL readout code. But we can think about the clock readout big picture later.

void lpt_pch_enable(struct intel_atomic_state *state,
struct intel_crtc *crtc);
drm/i915: Introduce lpt_pch_disable() Let's add lpt_pch_disable() as the counterpart to lpt_pch_enable(). Note that unlike the ilk+ code the fdi_link_train() and fdi_disable() calls are still left directly in intel_crt.c. If we wanted to move those we'd need to add lpt_pch_pre_enable(). But the two fdi direct fdi calls are pretry symmetric so it doesn't seem too bad to just keep them as is. v2: Make lpt_disable_pch_transcoder() static (lkp@intel.com) Cc: Dave Airlie <airlied@redhat.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211015071625.593-10-ville.syrjala@linux.intel.com Reviewed-by: Dave Airlie <airlied@redhat.com>

void lpt_pch_disable(struct intel_atomic_state *state,
struct intel_crtc *crtc);
drm/i915: Move LPT PCH readout code Nuke the hsw_get_ddi_port_state() eyesore by putting the readout code into intel_pch_display.c, and calling it directly from hsw_crt_get_config(). Note that the nuked TRANS_DDI_FUNC_CTL readout from hsw_get_ddi_port_state() is now etirely redundant since we get called from the encoder->get_config() so we already know we're dealing with the correct DDI port. Previously the code was called from a place where that wasn't known so it had to checked manually. v2: Clarify the TRANS_DDI_FUNC_CTL change (Dave) Nuke the now unused *TRANS_DDI_FUNC_CTL_VAL_TO_PORT() (Dave) Cc: Dave Airlie <airlied@redhat.com> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211018153525.21597-1-ville.syrjala@linux.intel.com Reviewed-by: Dave Airlie <airlied@redhat.com>
