Subject: [Intel-gfx] [PATCH v2 5/8] drm/i915/tc: Skip ref held check for TC legacy aux power wells
Date: Mon,  6 Apr 2020 18:11:54 -0700	[thread overview]
Message-ID: <20200407011157.362092-5-jose.souza@intel.com> (raw)
In-Reply-To: <20200407011157.362092-1-jose.souza@intel.com>

As part of ICL TC cold exit sequences we need to request aux power
well before lock the access to TC ports, so skiping the
intel_tc_port_ref_held() check for TC legacy ports.
