Ziyang Huang 41f20ac9bd mmc: meson-mx-sdhc: Fix initialization frozen issue 
commit 8c124d998ea0c9022e247b11ac51f86ec8afa0e1 upstream.

Commit 4bc31edebd ("mmc: core: Set HS clock speed before sending
HS CMD13") set HS clock (52MHz) before switching to HS mode. For this
freq, FCLK_DIV5 will be selected and div value is 10 (reg value is 9).
Then we set rx_clk_phase to 11 or 15 which is out of range and make
hardware frozen. After we send command request, no irq will be
interrupted and the mmc driver will keep to wait for request finished,
even durning rebooting.

So let's set it to Phase 90 which should work in most cases. Then let
meson_mx_sdhc_execute_tuning() to find the accurate value for data
transfer.

If this doesn't work, maybe need to define a factor in dts.

Fixes: e4bf1b0970 ("mmc: host: meson-mx-sdhc: new driver for the Amlogic Meson SDHC host")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
