Subject: [PATCH 03/13] clocksource: sh_tmu: Document r8a7779 binding
Date: Mon, 29 Sep 2014 02:23:36 +0200 [thread overview]
Message-ID: <1411950226-21598-3-git-send-email-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <1411950226-21598-1-git-send-email-daniel.lezcano@linaro.org>
From: Simon Horman <horms+renesas@verge.net.au>
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
