Subject: [PATCH v11 09/10] ACPI/IORT: Enable stall support for platform devices
Date: Mon, 25 Jan 2021 12:06:50 +0100	[thread overview]
Message-ID: <20210125110650.3232195-10-jean-philippe@linaro.org> (raw)
In-Reply-To: <20210125110650.3232195-1-jean-philippe@linaro.org>

Copy the "Stall supported" bit, that tells whether a named component
supports stall, into the dma-can-stall device property.
