Subject: [PATCH] drm/i915/dp: Expose force_dsc_enable through debugfs
Date: Fri,  5 Apr 2019 15:48:21 -0700	[thread overview]
Message-ID: <20190405224821.32435-1-manasi.d.navare@intel.com> (raw)

Currently we use force_dsc_enable to force DSC from IGT, but
we dont expose this value to userspace through debugfs.
This patch exposes this through the same dsc_fec_support
debugfs node per connector so that we can restore its value
back after the tests are completed.
