fdd85ec3eb sh: pfc: pin config get/set support.
This implements simple support for adjusting the pin config value via the
pinctrl API. The pinconf-generic code is abandoned for now until we've
got a chance to revamp the pinmux_type state tracking that's needed by
legacy code.

e3f805e897 sh: pfc: pinctrl legacy group support.
This follows the function support by simply doing 1 pin per group
encapsulation in order to keep with legacy behaviour. This will be
built on incrementally as SoCs define their own pin groups.

d93a891ff9 sh: pfc: pinctrl legacy function support.
This maps out all of the function types to pinctrl function groups.
Presently this is restricted to one pin per function to maintain
compatability with legacy behaviour. This will be extended as groups
are introduced and exiting users migrated.

ca5481c68e sh: pfc: Rudimentary pinctrl-backed GPIO support.
This begins the migration of the PFC core to the pinctrl subsystem.
Initial support is very basic, with the bulk of the implementation simply
being nopped out in such a way to allow registration with the pinctrl
core to succeed.

The gpio chip driver is stripped down considerably now relying purely on
pinctrl API calls to manage the bulk of its operations.

This provides a basis for further PFC refactoring, including decoupling
pin functions from the GPIO API, establishing pin groups, and so forth.
These will all be dealt with incrementally so as to introduce as few
growing and migratory pains to tree-wide PFC pinmux users today.

When the interfaces have been well established and in-tree users have
been migrated off of the legacy interfaces it will be possible to strip
down the core considerably, leading to eventual drivers/pinctrl rehoming.

afae021abe sh: pfc: Shuffle PFC support core.
This follows the intc/clk changes and shuffles the PFC support code under

06d5631f56 sh: pfc: Verify pin type encoding size at build time.
The encoding is tightly packed, and future changes (such as
pinconf-generic support) can easily lead to a situation where we violate
the encoding constraints and trample data bit/reg bits. This plugs in
some sanity checks by way of a BUILD_BUG_ON() to blow up if we fail to
fit.

b3c185a761 sh: pfc: Split out gpio chip support.
This implements a bit of rework for the PFC code, making the core itself
slightly more pluggable and moving out the gpio chip handling completely.

The API is preserved in such a way that platforms that depend on it for
early configuration are still able to do so, while making it possible to
migrate to alternate interfaces going forward.

This is the first step of chainsawing necessary to support the pinctrl
API, with the eventual goal being able to decouple pin function state
from the gpio API while retaining gpio chip tie-in for gpio pin functions
only, relying on the pinctrl/pinmux API for non-gpio function demux.

5f19f14fed sh: intc: Kill off special reservation interface.
At present reserving the IRLs in the IRQ bitmap in addition to the
dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being
allocated for the x3proto board.

The only reason to permit reservations was to lock down possible hardware
vectors prior to dynamic IRQ scanning, but this doesn't matter much given
that the hardware controller configuration is sorted before we get around
to doing any dynamic IRQ allocation anyways. Beyond that, all of the
tables are __init annotated, so quite a bit more work would need to be
done to support reconfiguring things like IRL controllers on the fly,
much more than would ever make it worth the hassle.

0f966d74cf PM / shmobile: Don't include SH7372's INTCS in syscore suspend/resume
Since the SH7372's INTCS in included into syscore suspend/resume,
which causes the chip to be accessed when PM domains have been
turned off during system suspend, the A4R domain containing the
INTCS has to stay on during system sleep, which is suboptimal
from the power consumption point of view.

For this reason, add a new INTC flag, skip_syscore_suspend, to mark
the INTCS for intc_suspend() and intc_resume(), so that they don't
touch it.  This allows the A4R domain to be turned off during
system suspend and the INTCS state is resrored during system
resume by the A4R's "power on" code.

b0e10211cb sh: pfc: ioremap() support
Add support for non-entity mapped PFC registers through
the use of struct resource and ioremap()/iounmap().

The PFC main data structure gets updated with a pointer
to a struct resources array that point out all register
windows used by the PFC instance. The register definitions
are kept as physical addresses but the PFC code will do
transparent conversion into virtual addresses whenever
register windows are specified using with struct resource.

To introduce as little performance penalty as possible the
virtual address of each data register is cached in memory.
The virtual address of each configuration register is however
calculated during run time. This because the configuration
is considered slow path so focus is instead put on keeping
memory foot print as small as possible.

The PFC register access  code is in this patch updated from
__raw_readN() / __raw_writeN() into ioreadN() / iowriteN().

This patch is needed to support the PFC block in r8a7779.

eda2030a5b sh: extend clock struct with mapped_reg member
Add a "mapped_reg" member to struct clk and use that
to keep the ioremapped register based on enable_reg.
