Subject: [PATCH v9 12/15] msi: platform: make platform_msi_create_device_domain() ACPI aware
Date: Tue, 7 Mar 2017 20:40:07 +0800 [thread overview]
Message-ID: <1488890410-15503-13-git-send-email-guohanjun@huawei.com> (raw)
In-Reply-To: <1488890410-15503-1-git-send-email-guohanjun@huawei.com>
From: Hanjun Guo <hanjun.guo@linaro.org>
The irqdomain creation that is carried out in:
platform_msi_create_device_domain()
relies on the fwnode_handle interrupt controller token to associate the
interrupt controller with a specific irqdomain. Current code relies on
the OF layer to retrieve a fwnode_handle for the device representing the
interrupt controller from its device->of_node pointer. This makes
platform_msi_create_device_domain() DT specific whilst it really is not
because after the merge of commit f94277af03ea ("of/platform: Initialise
dev->fwnode appropriately") the fwnode_handle can easily be retrieved
from the dev->fwnode pointer in a firmware agnostic way.
Update platform_msi_create_device_domain() to retrieve the interrupt
controller fwnode_handle from the dev->fwnode pointer so that it can
be used seamlessly in ACPI and DT systems.
