Geert Uytterhoeven b8856085c3 pinctrl: sh-pfc: r8a7795: Make PORT_GP_x() macros consistent
On r8a7795, PORT_GP_x() is a macro for defining GPIOs 0..x.
In all other sh-pfc code, PORT_GP_x() is a macro for defining GPIOs
0..(x-1).

Make the r8a7795 macro definitions consistent with the rest of the
sh-pfc codebase.

Geert Uytterhoeven 18fab3995e pinctrl: sh-pfc: Stop calling gpiochip_add_pin_range() on DT platforms
On platforms where the PFC/GPIO controller is instantiated from DT, the
mapping between GPIOs and pins is set up using the "gpio-ranges"
property in DT.

Hence stop setting up the mapping from C code on DT platforms.
This code is still used for SH or ARM-legacy platforms.

Linus Torvalds 88a99886c2 This is the bulk of pin control changes for the v4.3 development
cycle
 
 Core changes:
 
 - It is possible configure groups in debugfs.
 
 - Consolidation of chained IRQ handler install/remove replacing
   all call sites where irq_set_handler_data() and
   irq_set_chained_handler() were done in succession with a
   combined call to irq_set_chained_handler_and_data(). This
   series was created by Thomas Gleixner after the problem was
   observed by Russell King.
 
 - Tglx also made another series of patches switching
   __irq_set_handler_locked() for irq_set_handler_locked() which
   is way cleaner.
 
 - Tglx also wrote a good bunch of patches to make use of
   irq_desc_get_xxx() accessors and avoid looking up irq_descs
   from IRQ numbers. The goal is to get rid of the irq number
   from the handlers in the IRQ flow which is nice.
 
 Driver feature enhancements:
 
 - Power management support for the SiRF SoC Atlas 7.
 
 - Power down support for the Qualcomm driver.
 
 - Intel Cherryview and Baytrail: switch drivers to use raw
   spinlocks in IRQ handlers to play nice with the realtime
   patch set.
 
 - Rework and new modes handling for Qualcomm SPMI-MPP.
 
 - Pinconf power source config for SH PFC.
 
 New drivers and subdrivers:
 
 - A new driver for Conexant Digicolor CX92755.
 
 - A new driver for UniPhier PH1-LD4, PH1-Pro4, PH1-sLD8,
   PH1-Pro5, ProXtream2 and PH1-LD6b SoC pin control support.
 
 - Reverse-egineered the S/PDIF settings for the Allwinner
   sun4i driver.
 
 - Support for Qualcomm Technologies QDF2xxx ARM64 SoCs
 
 - A new Freescale i.mx6ul subdriver.
 
 Cleanup:
 
 - Remove platform data support in a number of SH PFC
   subdrivers.

Ben Hutchings 5b9eaa5659 pinctrl: sh-pfc: Implement pinconf power-source param for voltage switching
The pfc in the R8A7790 (and probably others in the R-Car gen 2 family)
supports switching SDHI signals between 3.3V and 1.8V nominal voltage,
and the SD driver should do that when switching to and from UHS modes.

Add a flag for pins that have configurable I/O voltage and SoC
operations to get and set the nominal voltage.  Implement the pinconf
power-source parameter using these operations.

Sergei Shtylyov 61bb3aef92 sh-pfc: fix sparse GPIOs for R-Car SoCs
The PFC driver causes the kernel to hang on the R-Car gen2 SoC based  boards
when the CPU_ALL_PORT() macro is fixed to reflect the reality, i.e. when the
GPIO space becomes actually sparse.  This happens because the _GP_GPIO() macro
includes  an indexed initializer which causes the "holes" (array entries filled
with all 0s) between the groups  of the existing GPIOs; and the driver can't
cope with that.  There seems to  be no reason to use the indexed initializer,
so we can remove the index specifier and so avoid the "holes".

Geert Uytterhoeven c7977ec4a3 pinctrl: sh-pfc: Convert to platform_get_*()
If the pin function controller (which can be a GPIO controller) is
instantiated before the interrupt controllers, due to the ordering in
the DTS, the irq domains for the interrupt controllers referenced by its
"interrupts-extended" property cannot be found yet:

    irq: no irq domain found for /interrupt-controller@e61c0000 !

As the sh-pfc driver accesses the platform device's resources directly,
it cannot find the (optional) IRQ resources, and thinks no interrupts
are available. This may lead to failures later, when GPIOs are used as
interupts:

    gpio-keys keyboard: Unable to claim irq 0; error -22
    gpio-keys: probe of keyboard failed with error -22

To fix this, add support for deferred probing to sh-pfc, by converting
the driver from direct platform device resource access to using the
platform_get_resource() and platform_get_irq() helpers.

Note that while this fixes the root cause worked around by commit
e4ba0a9bdd ("ARM: shmobile: r8a73a4: Move pfc node to work around
probe ordering bug"), I strongly recommend against reverting the
workaround now, as this would lead to lots of probe deferrals in drivers
relying on pinctrl. This may be reconsidered once the DT code starts
taking into account phandle dependencies during device instantation.
