Subject: [PATCH v2 9/9] Soundwire: intel_init: save Slave(s) _ADR info in sdw_intel_ctx
Date: Thu, 16 Jul 2020 23:09:47 +0800	[thread overview]
Message-ID: <20200716150947.22119-10-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20200716150947.22119-1-yung-chuan.liao@linux.intel.com>

Save ACPI information in context so that we can match machine driver
with sdw _ADR matching tables.
