Hi Paul & Benoit,
Does this series look OK to you guys to queue or ack?

> AM43x PRCM support (excluding clock tree) is being added with this
> series. AM43x reuses most of the IP's from AM335x, as that is the
> case, much of the AM335x hwmod data is reused.
>
> I am aware that this series adds around +1K lines to platform. We in
> TI, here are making efforts to clean platform code gradually and keep
> to minumum the code being added to support new SoC's. Please note that
> this SoC support series has positive diffstat of just above 1K only.
> This compared to last SoC that was supported in OMAP family during
> last merge window is way less (this is only around 1/8th postive
> diffstat of it). Clock data is not added in this series, instead
> directly clock tree in DT with driver would be used, this is a work in
> progress. And as seen from recent OMAP clock tree DT conversion
> series, there are serious efforts ongoing to that end. Also we will
> start working on moving hwmod away from platform folders. In addition,
> recently there was a PRCM cleanup by Rajendra Nayak that removed near
> to 11K lines.
>
> Considering the above facts, I request the maintainers to consider
> this series for the next merge window.

> Currently there is no public TRM available for AM43x.
>
> Hwmod database of AM335x is reused by moving common elements to a new
> array (most of AM335x IP's are present in AM43x) and keeping separate
> arrays for elements that are specific only to either one of AM335x or
> AM43x. And in the cases where relevant IP is present in both that has
> difference in details like CLKCTRL register offsets, it is being
> updated at runtime based on the SoC detected.
>
> Powerdomain & Clockdomain data has been added separately as it was not
> giving much advantage reusing AM335x ones (runtime updates required
> was getting too ugly). But as AM43x PRCM functionality is similar to
> OMAP4, power domain, clock domain & hwmod operations are reused from
> OMAP4.
>
> A single header file has been added to provide all AM43x PRCM defines.
>
> Here sequencewise, initially AM335x hwmod is modified to have it's
> fields get updated at runtime (wherever element is shared and has
> some difference with AM43x). Then power domain, clock domain for AM43x
> is added and finally AM335x hwmod database is updated with AM43x
> specifics.
>
> This series is being developed with additional clock tree changes that
> are being DT'fied.
>
> Additional DTS changes (posted separate from this series) are also
> required for hwmod to get register target address space as most of
> AM335x hwmod address space details has been recently cleaned up and
> moved to DTS.
