[ Upstream commite7ae08d398] Bail out early from sysc_wait_softreset() just like we do in sysc_reset() if there's no sysstatus srst_shift to fix a bogus resetdone warning on enable as suggested by Grygorii Strashko <grygorii.strashko@ti.com>. We do not currently handle resets for modules that need writing to the sysstatus register. If we at some point add that, we also need to add SYSS_QUIRK_RESETDONE_INVERTED flag for cpsw as the sysstatus bit is low when reset is done as described in the am335x TRM "Table 14-202 SOFT_RESET Register Field Descriptions" Fixes:d46f9fbec7("bus: ti-sysc: Use optional clocks on for enable and wait for softreset bit") Suggested-by: Grygorii Strashko <grygorii.strashko@ti.com> Acked-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Sasha Levin <sashal@kernel.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.
