Wysocki" Cc: Darren Hart , Alexandre Courbot , Linus Walleij , Arnd Bergmann , Mika Westerberg , linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org Subject: [PATCH] ACPI / GPIO: Pass index to acpi_get_gpiod_by_index() when using properties Date: Tue, 28 Oct 2014 13:15:27 +0200 Message-Id: <1414494927-204923-1-git-send-email-mika.westerberg@linux.intel.com> X-Mailer: git-send-email 2.1.1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org acpi_dev_add_driver_gpios() makes it possible to set up mapping between properties and ACPI GpioIo resources in a driver, so we can take index parameter in acpi_find_gpio() into use with _DSD device properties now. This index can be used to select a GPIO from a property with multiple GPIOs: Package () { "data-gpios", Package () { \_SB.GPIO, 0, 0, 0, \_SB.GPIO, 1, 0, 0, \_SB.GPIO, 2, 0, 1, } } In order to retrieve the last GPIO from a driver we can simply do: desc = devm_gpiod_get_index(dev, "data", 2); and so on.
