Hi Olof, Hi Kevin, Hi Arnd,

Please consider these second round of Renesas ARM based SoC fixes for v4.6.

This fix allows serial to work on r8a7795-based boards where the optional
scif clock is not populated.

This pull request is based on the previous round of
such requests, tagged as renesas-fixes-for-v4.6,
which I have already sent a pull-request for.


The following changes since commit c531fb27e9699eaee478ee5686a3cca5dee73602:

  ARM: shmobile: timer: Fix preset_lpj leading to too short delays (2016-04-20 08:52:55 +1000)

clk_get() on a disabled clock node will return -EPROBE_DEFER, which can
cause drivers to be deferred forever if such clocks are referenced in
their devices' clocks properties.

Update the disabled external scif clock node so that it
is not disabled to prevent this.
