clk81 is a composite clock which parents all the peripheral clocks of the platform. It is a critical clock which is used as provided by the bootloader. We don't want to change its rate or reparent it, ever. Remove the CLK_IGNORE_UNUSED on the mux and divider. These clock can't gate so the flag is useless, and the gate is already critical, so the clock won't ever be unused. Remove CLK_SET_RATE_NO_REPARENT from mux, it is useless since the mux is read-only. Remove CLK_SET_RATE_PARENT from the gate and divider and use ro_ops for the divider. A peripheral clock should not try to change the rate of clk81. Stopping the rate propagation is good way to make sure such request would be ignored. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
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.
