Subject: [PATCH v8 5/9] ACPI/IORT: Enable stall support for platform devices
Date: Thu, 12 Nov 2020 13:55:17 +0100 [thread overview]
Message-ID: <20201112125519.3987595-6-jean-philippe@linaro.org> (raw)
In-Reply-To: <20201112125519.3987595-1-jean-philippe@linaro.org>
Copy the "Stall supported" bit, that tells whether a platform device
supports stall, into the fwspec struct.
