Subject: drm/i915: Unify ICP and MCC hotplug pin tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: d09ad3e7af3ab230323c2c00e190f801feb3a343
Patch-mainline: v5.5-rc1
References: bsc#1152489
The MCC hpd table is just a subset of the ICP table; we can eliminate it
and use the ICP table everywhere. The extra pins in the table won't be
a problem for MCC since we still supply an appropriate hotplug trigger
mask anywhere the pin table is used.
