drm/i915/icl: Add register definition for DFLEXDPMLE

Manasi Navare · pzanoni-intel · commit a2bc69a1a9d6 · 2018-06-01T16:06:16.000-07:00
DFLEXDPMLE register is required to tell the FIA hardware which main links of DP are enabled on TCC Connectors. FIA uses this information to program PHY to Controller signal mapping. This register is applicable in both TC connector's Alternate mode as well as DP connector mode. v2: * Remove _ICL prefix since the reg is first introduced in ICL (Paulo) * s/ICL/icl in commit message (Lucas) Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Animesh Manna <animesh.manna@intel.com> Cc: Madhav Chauhan <madhav.chauhan@intel.com> Cc: Anusha Srivatsa <anusha.srivatsa@intel.com> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1527275032-4555-1-git-send-email-manasi.d.navare@intel.com
