c7ed1ab3f7 serial: sh-sci: clkdev updates for MSTP gating.
This fixes up some of the I/D/F clock ambiguity in the sh-sci driver.
The interface clock in most cases just wraps back to the peripheral
clock, while the function clock wraps in to the MSTP bits. As the logic
was somewhat inverted, this cleans that up, and also enables all CPUs
with SCI MSTP bits to match function clocks through clkdev lookup.

As a result, this gets rid of the clk string abuse on the sh side, and
the clock string will be killed off once the ARM code has had a chance to
sync up. This also enables MSTP gating on CPUs like 7786 which had never
wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785,
and SH7786.

0a5f337ecd sh: introduce struct clk_div4_table
This patch introduces struct clk_div4_table. The structure
will be used to keep div4 specific data, and is with this
patch replacing the struct clk_div_mult_table pointer arg
used by the sh_clk_div4_register() functions.

801cd56e3e sh: break out enable/reparent div4 clocks on sh7723
Break out sh7723 div4 clocks for SIU and IRDA as
reparent / enable clocks. Similar to the SIU clock
patch for sh7722 by Guennadi.

cc58f597af sh: drop static UIO clocks for sh7722, sh7723 and sh7724
The Runtime PM patch for UIO driver implements coarse grained
dynamic power management for UIO devices. With that patch in
place we can get rid of the static clock configuration. Which
in turn makes it possible for cpuidle to enter deeper sleep.

c521dc0203 sh: sh7723 clock framework rewrite V2
This patch contains V2 of the sh7723 clock framework
rewrite. The new code makes use of the recently merged
div4, div6 and mstp32 helper code. Both extal and dll
are supported as input clocks to the pll.
