Subject: [PATCH 4/4] cxl/acpi: Use common IW/IG decoding
Date: Thu, 27 Jan 2022 13:29:11 -0800	[thread overview]
Message-ID: <20220127212911.127741-5-ben.widawsky@intel.com> (raw)
In-Reply-To: <20220127212911.127741-1-ben.widawsky@intel.com>

Now that functionality to decode interleave ways and granularity is in
a common place, use that functionality in the cxl_acpi driver.
