[PATCH] clocksource: em_sti: convert to clk_prepare/unprepare

[Simon Horman]

From: Shinya Kuribayashi <shinya.kuribayashi.px@renesas.com>

Add calls to clk_prepare and unprepare so that EMMA Mobile EV2 can
migrate to the common clock framework.

[GIT PULL] Renesas ARM based SoC Clocksource updates for v3.14

[Simon Horman]

Hi Daniel,

please consider this Renesas ARM based SoC Clocksource update for v3.14.

I would also like to request that you make a branch available
for me to use as a base for a branch containing SoC changes
targeted at v3.14 that depend on this clocksource update.

Thanks

[PATCH 1/3] clocksource: sh_cmt: Document SoC specific bindings

[Simon Horman]

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 Compare Match Timer (CMT) driver to follow this
convention.

[PATCH 2/3] clocksource: sh_mtu2: Document r7s72100 binding

[Simon Horman]

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 Multi-Function Timer Pulse Unit 2 (MTU2) driver
to follow this convention.
