[v2,0/5] ti-sysc support for PRUSS

Message

Hi Tony,

The following is a revised series of the ti-sysc support for PRUSS.
Please refer to the original series cover-letter [1] for details.

Following are the main changes in v2:
 - Drop the enabling of the interconnect nodes from various AM335x and
   AM437x board dts files (last 7 patches from original series)
 - Enable the target-module node for AM437x by default. None of the
   current AM437x board dts files use AM4372, so there should not be
   any regressions.

We can drop the status=disabled in the am33xx.dtsi file once we add the
SoC revision support for AM335x SoCs. This is already disabled before the
series as well. I have identified a few boards which use the older SoCs
that can disable the node in dts, but there were few others which can
use any of the SoCs, so those will definitely require the SoC device
match logic and an additional PRUSS disable quirk in the ti-sysc bus
driver.

regards
Suman

OK thanks, applied and pushed out into omap-for-v5.7/ti-sysc-drop-pdata.
