Subject: [RFC PATCH 11/15] cxl/acpi: Use common IW/IG decoding
Date: Wed, 13 Apr 2022 11:37:16 -0700	[thread overview]
Message-ID: <20220413183720.2444089-12-ben.widawsky@intel.com> (raw)
In-Reply-To: <20220413183720.2444089-1-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.
