Shawn Lin 2dc1d1a871 clk: Don't show the incorrect clock phase [ Upstream commit `1f9c63e8de` ] It's found that the clock phase output from clk_summary is wrong compared to the actual phase reading from the register. cat /sys/kernel/debug/clk/clk_summary \| grep sdio_sample sdio_sample 0 1 0 50000000 0 -22 It exposes an issue that clk core, clk_core_get_phase, always returns the cached core->phase which should be either updated by calling clk_set_phase or directly from the first place the clk was registered. When registering the clk, the core->phase geting from ->get_phase() may return negative value indicating error. This is quite common since the clk's phase may be highly related to its parent chain, but it was temporarily orphan when registered, since its parent chains hadn't be ready at that time, so the clk drivers decide to return error in this case. However, if no clk_set_phase is called or maybe the ->set_phase() isn't even implemented, the core->phase would never be updated. This is wrong, and we should try to update it when all its parent chains are settled down, like the way of updating clock rate for that. But it's not deserved to complicate the code now and just update it anyway when calling clk_core_get_phase, which would be much simple and enough.

README

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.
