Initially we configured the PAD_CTRL1 register at probe/bind time. However it seems the HDMI controller will modify some of the bits in this register by itself. On the A10 it is particularly annoying as it toggles the output invert bits, which inverts the colors on the display output. The U-boot driver this driver is based on sets this register twice, though it seems it's only needed for actual display output. Hence we move it to the mode_set function.

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.
