Subject: [Intel-gfx] [CI v4] drm/i915/dp: Disable Port sync mode correctly on teardown
Date: Thu, 19 Dec 2019 17:04:03 -0800 [thread overview]
Message-ID: <20191220010403.29111-1-manasi.d.navare@intel.com> (raw)
While clearing the Ports ync mode enable and master select bits
we need to clear the register completely instead of using disable masks
v3:
* Remove reg variable (Matt)
v2:
* Just write 0 to the reg (Ville)
* Rebase
