Stephen Boyd 62e59c4e69 clk: Remove io.h from clk-provider.h 
Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

Found with this grep:

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.

Paul Cercueil bc5d922c93 clk: ingenic: Fix round_rate misbehaving with non-integer dividers 
Take a parent rate of 180 MHz, and a requested rate of 4.285715 MHz.
This results in a theorical divider of 41.999993 which is then rounded
up to 42. The .round_rate function would then return (180 MHz / 42) as
the clock, rounded down, so 4.285714 MHz.

Calling clk_set_rate on 4.285714 MHz would round the rate again, and
give a theorical divider of 42,0000028, now rounded up to 43, and the
rate returned would be (180 MHz / 43) which is 4.186046 MHz, aka. not
what we requested.

Fix this by rounding up the divisions.

Paul Burton fb615d61b5 Update MIPS email addresses 
MIPS will soon not be a part of Imagination Technologies, and as such
many @imgtec.com email addresses will no longer be valid. This patch
updates the addresses for those who:

 - Have 10 or more patches in mainline authored using an @imgtec.com
   email address, or any patches dated within the past year.

 - Are still with Imagination but leaving as part of the MIPS business
   unit, as determined from an internal email address list.

 - Haven't already updated their email address (ie. JamesH) or expressed
   a desire to be excluded (ie. Maciej).

 - Acked v2 or earlier of this patch, which leaves Deng-Cheng, Matt &
   myself.

New addresses are of the form firstname.lastname@mips.com, and all
verified against an internal email address list.  An entry is added to
.mailmap for each person such that get_maintainer.pl will report the new
addresses rather than @imgtec.com addresses which will soon be dead.

Instances of the affected addresses throughout the tree are then
mechanically replaced with the new @mips.com address.

The jz4740-cgu driver already has access to the CGU, so it makes sense
to move the few remaining accesses to the CGU from arch/mips/jz4740
there too. Move the jz4740_clock_{suspend,resume} functions there for
such consistency. The arch/mips/jz4740/clock.c file now contains nothing
more of use & so is removed.

Paul Burton ed286ca5d6 MIPS, clk: move jz4740 UDC auto suspend functions to jz4740-cgu 
The jz4740-cgu driver already has access to the CGU, so it makes sense
to move the few remaining accesses to the CGU from arch/mips/jz4740
there too. Move the jz4740_clock_udc_{dis,en}able_auto_suspend functions
there for such consistency.

Paul Burton ff1930c6bd MIPS,clk: migrate JZ4740 to common clock framework 
Migrate the JZ4740 & the qi_lb60 board to use common clock framework
via the new Ingenic SoC CGU driver. Note that the JZ4740-specific
debugfs code is removed since common clock framework provides its own
debug capabilities.

Paul Burton b066303fb3 clk: ingenic: add driver for Ingenic SoC CGU clocks 
This driver supports the CGU clocks for Ingenic SoCs. It is generic
enough to be usable across at least the JZ4740 to the JZ4780, and will
be made use of on such devices in subsequent commits. This patch by
itself only adds the SoC-agnostic infrastructure that forms the bulk of
the CGU driver for the aforementioned further commits to make use of.
