Subject: [PATCH 08/17] coresight: acpi: Static funnel support
Date: Thu, 29 Aug 2019 14:28:33 -0600	[thread overview]
Message-ID: <20190829202842.580-9-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <20190829202842.580-1-mathieu.poirier@linaro.org>

From: Suzuki K Poulose <suzuki.poulose@arm.com>

The ACPI bindings for CoreSight has been updated to add the device
id for non-programmable CoreSight funnels (aka static funnels) as of
v1.1 [0]. Add the ACPI id for static funnels in the driver.
