The HDMI driver is currently enabling all clocks at probe time and keeps the power-domain connected to the HDMI encoder enabled. Move all activation code to vc4_hdmi_encoder_enable() and make sure the clks and power domain are released when the HDMI encoder is not used by adding deactivation steps in vc4_hdmi_encoder_disable(). Note that the sequencing imposed by the IP requires that we move vc4_hdmi_encoder_mode_set() code into vc4_hdmi_encoder_enable().

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.
