On Amlogic GX SoCs, there is two CEC controllers : - An Amlogic CEC custom in the AO domain - The Synopsys HDMI-TX Controller in the EE domain Each of these controllers needs a 32.768KHz clock, but there is two paths : - In the EE domain, the "32k_clk" this patchs is adding - In the AO domain, with a more complex dual divider more precise setup The AO 32K clock support will be pushed later in the corresponding gxbb-aoclk driver when the AE CEC driver is ready. The EE 32k_clk must be pushed earlier since mainline support for CEC in the Synopsys HDMI-TX controller is nearby.

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.
