There is exactly one board in the kernel that defines platform data for the GPIO NAND driver. Use the feature to provide a lookup table for the GPIOs in the board file so we can convert the driver as a whole to just use GPIO descriptors. After this we can cut the use of <linux/of_gpio.h> and use the GPIO descriptor management from <linux/gpio/consumer.h> alone to grab and use the GPIOs used in the driver. I also created a local struct device *dev in the probe() function because I was getting annoyed with all the &pdev->dev dereferencing.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
