Date: Tue, 11 Feb 2014 11:50:00 -0800 From: David Daney <ddaney.cavm@...il.com> To: Grant Likely <grant.likely@...aro.org>, Rob Herring <robh+dt@...nel.org>, devicetree@...r.kernel.org, Linus Walleij <linus.walleij@...aro.org>, Alexandre Courbot <gnurou@...il.com>, linux-gpio@...r.kernel.org Cc: linux-kernel@...r.kernel.org, David Daney <david.daney@...ium.com> Subject: [PATCH v2 2/2] of/gpio: Automatically decode OF_GPIO_OPEN_DRAIN and OF_GPIO_OPEN_SOURCE flags in gpiolib. From: David Daney <david.daney@...ium.com> Just as gpiod_get() automatically interprets the OF_GPIO_ACTIVE_LOW flag from the device tree, add handling for OF_GPIO_OPEN_DRAIN and OF_GPIO_OPEN_SOURCE. This keeps the details of handling open-drain GPIOs in the core GPIO code, and out of the individual drivers.
