Subject: [PATCH 3.16.y-ckt 048/126] ARM: dts: Enable PWM node by default for s3c64xx

3.16.7-ckt5 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tomasz Figa <tomasz.figa@...il.com>

commit 5e794de514f56de1e78e979ca09c56a91aa2e9f1 upstream.

The PWM block is required for system clock source so it must be always
enabled. This patch fixes boot issues on SMDK6410 which did not have
the node enabled explicitly for other purposes.

Fixes: eeb93d02 ("clocksource: of: Respect device tree node status")
