drm/i915/tgl: Add hpd interrupt handling
Add hotdplug detection for all ports on TGP. icp_hpd_detection_setup() is refactored to be shared with TGP. While we increase the number of pins, add a BUILD_BUG_ON() to avoid going over the number of bits allowed. v2: use BITS_PER_TYPE and correct type for BUILD_BUG_ON() check (requested by Ville) Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Jose Souza <jose.souza@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190725234813.27179-2-lucas.demarchi@intel.com
