Date: Thu, 15 Mar 2012 16:32:06 -0500 From: Seth Forshee <seth.forshee@...onical.com> To: Matthew Garrett <mjg@...hat.com>, platform-driver-x86@...r.kernel.org Cc: Richard Purdie <rpurdie@...ys.net>, linux-kernel@...r.kernel.org, Seth Forshee <seth.forshee@...onical.com> Subject: [PATCH v3 0/2] Add driver for Apple gmux device Apple laptops with hybrid graphics have a device named gmux that is used for switching between GPUs and backlight control. On many models this is the only reliable method for controlling the backlight. This series adds initial support for the gmux device, along with anciallary support for disabling apple_bl when the gmux device is detected. Initially only backlight control is supported. Changes since v2: - Add prerequisite patch for apple_bl to support disabling this backlight when a gmux backlight device is present. - Unregister acpi_video when a gmux backlight device is present.
