clocksource: sh_tmu: Document r8a7778 binding

2014-10-27T01:00:36+00:00

The r8a7778 is very similar to the r8a7779, and already handled by
the current driver in the non-DT case.

clocksource: sh_tmu: Document R-Mobile r8a7740 binding

2014-10-27T01:00:35+00:00

Compared to the r8a7779, the r8a7740 lacks the input capture register,
which is not used by the driver (the current driver already handles the
r8a7740 in the non-DT case).

clocksource: sh_tmu: Document r8a7779 binding

2014-09-06T01:20:53+00:00

In general Renesas hardware is not documented to the extent
where the relationship between IP blocks on different SoCs can be assumed
although they may appear to operate the same way. Furthermore the
documentation typically does not specify a version for individual
IP blocks. For these reasons a convention of using the SoC name in place
of a version and providing SoC-specific compat strings has been adopted.

Although not universally liked this convention is used in the bindings
for a number of drivers for Renesas hardware. The purpose of this patch is
to update the Renesas R-Car Timer Unit (TMU) driver to follow this
convention.

* I plan to follow up with a patch patch to use the new binding in the
  dtsi files for the r8a7779 SoC.
commit 471269b790aec03385dc4fb127ed7094ff83c16d

v2
* Suggestions by Mark Rutland and Sergei Shtylyov
  - Compatible strings should be "one or more" not "one" of those listed
  - Describe the generic binding as covering any MTU2 device
  - Re-order compat strings from most to least specific

v3
* Suggested by Laurent Pinchart
  - Reword in keeping with a similar though more extensive patch for CMT

clocksource: sh_tmu: Add DT support

2014-07-04T13:50:28+00:00

Document DT bindings and parse them in the TMU driver.
