We need to let ti-sysc driver manage clockdomain autoidle for the duration of of reset, enable and idle. And we need to do it before we enable the clock and after we disable it. Currently we are still relying on platform callbacks indirectly managing clockdomain autoidle. But I noticed that for device tree only probed drivers it now happens only after we enabling the clocks and before we disable the clocks, while it should be the other way around. So far I have not noticed any issues with this though. Let's add new ti_sysc_clkdm_deny_idle() and ti_sysc_clkdm_allow_idle() functions for ti-sysc driver to use to manage clockdomains directly via platform data callbacks. Note that we can implement the clockdomain functions in pdata-quirks.c as for probing devices without "ti,hwmods" custom property we don't need to use the other platform data callbacks. Let's do this in one patch as there's is still an unlikely chance we may need to apply this as a fix for v5.2 for dropping legacy platform data for some devices. We also do have the option of adding back the platform data if needed in case of trouble. Tested-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> |

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.
