There are clk sync issue on TRCM mode for RK3308/RK1808/PX30,
and the previous soluation is to make TX/RX reset at the same
time to fix that. Unfortunately, it fails on PX30-I2S0, because
the reset-TX and reset-RX bits can't be addressed at the same time.
Now, we use another way to fix it:
reset_control_assert(i2s_tdm->tx_reset);
reset_control_assert(i2s_tdm->rx_reset);
|
gate the i2s src clk
|
reset_control_deassert(i2s_tdm->tx_reset);
reset_control_deassert(i2s_tdm->rx_reset);
|
ungate the i2s src clk
as shown above, use the pair gate/ungate src clk to make the
TX/RX reset at the same time.

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.
