According to measure on i.MX7ULP and i.MX8ULP, the RCS done needs about 3400us and 6700us respectively. So current 20us timeout is not enough. When reconfiguring is on-going, unlock and configure CS will lead to unknown result. Increase the wait timeout value to 10ms and check the return value of RCS wait to fix the issue Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Alice Guo <alice.guo@nxp.com> Reviewed-by: Jacky Bai <ping.bai@nxp.com> Acked-by: Jason Liu <jason.hui.liu@nxp.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Link: https://lore.kernel.org/r/20220825083256.14565-5-alice.guo@oss.nxp.com Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@linux-watchdog.org>
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.
