It's found that the final phase set by driver doesn't match that of
the output from clk_summary:
dwmmc_rockchip fe310000.dwmmc: Successfully tuned phase to 346
mmc0: new ultra high speed SDR104 SDIO card at address 0001
cat /sys/kernel/debug/clk/clk_summary | grep sdio_sample
sdio_sample 0 1 0 50000000 0 0
It seems the cached core->phase isn't updated after the clk was
registered. So fix this issue by updating the core->phase if setting
phase successfully.
Fixes: 9e4d04adeb ("clk: add clk_core_set_phase_nolock 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.
