From: Rodrigo Vivi Date: Mon, 29 Jan 2018 23:22:20 +0000 (-0800) Subject: drm/i915: For HPD connected port use hpd_pin instead of port. X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7533eb4f89f70f9efb81171bcfa528f51d3d2618;p=openwrt%2Fstaging%2Fblogic.git drm/i915: For HPD connected port use hpd_pin instead of port. Let's try to simplify this mapping to hpd_pin -> bit instead using port. So for CNL with port F where we have this port using hdp_pin and bits of other ports we don't need to duplicated the mapping. But for now this is only a re-org with no functional change expected. v2: Add missing lines and nuke @port reference from code documentation.
