Document the on-chip CMT devices included in r8a7740 and sh73a0.
Included in this patch is DT binding documentation for 32-bit CMTs
CMT0, CMT2, CMT3 and CMT4. They all contain a single channel and are
quite similar however some minor differences still exist:
- "Counter input clock" (clock input and on-device divider)
One example is that RCLK 1/1 is supported by CMT2, CMT3 and CMT4.
- "Wakeup request" (supported by CMT0 and CMT2)
Because of this one unique compat string per CMT device is selected.

This patch reworks the DT binding documentation for the 6-channel
48-bit CMTs known as CMT1 on r8a7740 and sh73a0.
After the update the same style of DT binding as the rest of the upstream
SoCs will now also be used by r8a7740 and sh73a0. The DT binding "cmt-48"
is removed from the DT binding documentation, however software support for
this deprecated binding will still remain in the CMT driver for some time.

From: Magnus Damm <damm+renesas@opensource.se>
The R-Car Gen3 SoCs so far come with a total for 4 on-chip CMT devices:
- CMT0
- CMT1
- CMT2
- CMT3
CMT0 includes two rather basic 32-bit timer channels. The rest of the on-chip
CMT devices support 48-bit counters and have 8 channels each.
Based on the data sheet information "CMT2/3 are exactly same as CMT1"
it seems that CMT2 and CMT3 now use the CMT1 compat string in the DTSI.
Clarify this in the DT binding documentation by describing R-Car Gen3 and
RZ/G2 CMT1 as "48-bit CMT devices".

I think plural was fine here, though, as it applies to the whole family.
If you disagree, you should probably add a "the".

Hi Magnus,
I think this series should include the Clocksource maintainers as
recipients:
Daniel Lezcano <daniel.lezcano@linaro.org>
Thomas Gleixner <tglx@linutronix.de>
And LKML for good measure.

Will do after a bit more waiting time for potential feedback from
folks with access to Renesas documents. In particular I expected some
opinions about the difference between how the DT compat strings are
handled for CMT1/CMT2/CMT3 on R-Car Gen3 (as described in patch 8)
compared to sh73a0/r8a7740 (as described in patch 1).
I also need to rebase on top of that CMT DT biniding document patch
that covers most of the R-Car Gen3 SoCs.
Cheers,
