To: linux-arm-kernel
The Broadcom Stingray SoC is a new member in Broadcom iProc
SoC family.
This patch adds initial DTS files for Broadcom Stingray SoC
and two of its reference boards (bcm958742k and bcm958742t).
We have lot of reference boards and large number of devices
in Broadcom Stingray SoC so eventually we will have quite
a few DTS files for Stingray. To tackle, we have added a
separate directory for Stingray DTS files.

We have two instance of PL022 SPI controllers, one instance of
DMA PL330, and one non-secure SP805 Watchdog on Stingray SOC.
This patch adds DT nodes for the above mentioned devices in
Stingray DT.

The Stingray SoC has two instances of SDHCI controller
and one instance of iProc PWM.
Let's enable above mentioned devices in Stingray DT.

Grouping as one patchset for review is fine, but when you submit this
for merge you need to split it up:
- Documentation/devicetree can go with the driver pieces or with the
DT changes, your choice
- DTS/DTSI changes should go through the Broadcom maintainers to arm-soc
- clk changes should go to clk maintainers.
Also, there's usually no need to split up a DT introduction and having
separate pieces for NAND/pinctrl/GPIO/etc: They can all go in the main
DT submission patch.

Only PATCH3 needs to go through clk maintainers rest all patches
are DT bindings document and DTS changes which can go through
Broadcom tree. Right ??

Yes, we have already squashed DTS patches from same author into
one DTS patch except NAND, PINCTRL and GPIO patches.
The NAND, PINCTRL, and GPIO patches were not squashed into
one patch for easy review but since you suggest I will squash these
three DTS patches into one DTS patch.

Patch 2 and 3 should go through the clock maintainers, and I can take
the remaining patches through the Broadcom ARM/ARM64 SoC pull requests,
no problem.
Unless there are specific changes requested which warrant a v4, I can
coordinate with Stephen and Mike to make sure that they take the
appropriate patches.

We have minor changes in clk driver to address Stephen's comments.
I will send v4 patchset will updated clk driver.
