Geert Uytterhoeven bd79c92039 pinctrl: sh-pfc: Rename 2-parameter CPU_ALL_PORT() variant
There are two variants of the CPU_ALL_PORT() macro in use:
  1. A three-parameter variant, to be provided for SoCs with a linear
     GPIO pin space ("PORT style"),
  2. A two-parameter variant, to be provided for SoCs with 32-port GPIO
     banks ("GP port style").

Rename the 2-parameter variant to CPU_ALL_GP(), to avoid confusion, and
to increase naming consistency.

Geert Uytterhoeven 69f7be1c63 pinctrl: sh-pfc: Absorb enum IDs in PINMUX_CFG_REG_VAR() macro
Currently the PINMUX_CFG_REG_VAR() macro must be followed by
initialization data, specifying all enum IDs.  Hence the macro itself
does not know anything about the enum IDs, preventing the macro from
performing any validation on it.

Make the macro accept the enum IDs as a parameter, and update all users.
Note that array data enclosed by curly braces cannot be passed to a
macro as a parameter, hence both the register field widths and the enum
IDs are wrapped using the GROUP() macro.

No functional changes.

Geert Uytterhoeven b8ba194ca5 pinctrl: sh-pfc: r8a7791: Fix VIN1 versioned groups
The naming of the "b" versions of the VIN1 pin groups is a bit odd, in
that the "_b" appears in the middle of the names, instead of as a
suffix.

Increase consistency with other SoCs by making R-Car M2-W and M2-N, and
RZ/G1M and RZ/G1N, use the recently added optional "version" argument of
the VIN_DATA_PIN_GROUP() macro.

Note that this breaks backwards compatibility with existing DTBs, but
there are no upstream users of the "vin1_b_*" names.

Geert Uytterhoeven 07d36d2908 pinctrl: sh-pfc: Improve core and user API separation
The Renesas Pin Function Controller uses two header files:
  - sh_pfc.h, for use by both core code and SoC-specific drivers,
  - core.h, for internal use by the core code only.

Several SoC-specific drivers include core.h, as they need the sh_pfc
structure, which is passed explicitly to the various SoC-specific
callbacks, and used there.

Hence move its definition from core.h to sh_pfc.h, and remove the
inclusion of core.h from all SoC-specific files.

Sergei Shtylyov 87f27fe1a7 sh-pfc: r8a7791: fix typo in MLB_CLK
The R8A7791 manual sometimes calls the signal MLB_CLK and sometimes MLB_CK; the
latter can only be encountered in the PFC section and  is probably  just a typo
(this  signal is always called MLB_CLK in the R8A7790  manual). Fix occurences
of MLB_CK throughout the R8A7791 PFC driver.

Based on original patch by Andrey Gusakov <andrey.gusakov@cogentembedded.com>.

Sergei Shtylyov 302fb17817 sh-pfc: r8a7791: fix CAN pin groups
I had made last-minute changes before submitting the patch "sh-pfc: r8a7791:
add CAN pin groups"; now I'm seeing that they weren't complete: I had missed
update to the pin group names in pin[01]_groups[]. Drop the "_a" suffixes there.

Linus Torvalds bd698cf659 This is the bulk of pin control changes for the v3.16
development cycle:
 
 - Antoine Tenart made the get_group_pins() vtable entry
   optional.
 
 - Antoine also provides an entirely new driver for the
   Marvell Berlin SoC. This is unrelated to the existing
   MVEBU hardware driver and warrants its own separate
   driver.
 
 - Reflected from the GPIO subsystem there is a number of
   refactorings to make pin control drivers with gpiochips
   use the new gpiolib irqchip helpers. The following
   drivers were converted to use the new infrastructure:
 
   - ST Microelectronics STiH416 and friends
 
   - The Atmel AT91
 
   - The CSR SiRF (Prima2)
 
   - The Qualcomm MSM series
 
 - Massive improvements in the Qualcomm MSM driver from
   Bjorn Andersson, Andy Gross and Kumar Gala. Among those
   new support for the IPQ8064 and MSM8x74 SoC variants.
 
 - Support for the Freescale i.MX6 SoloX SoC variant.
 
 - Massive improvements in the Allwinner sunxi driver from
   Boris Brezillon, Maxime Ripard and Chen-Yu Tsai.
 
 - Renesas PFC updates from Laurent Pinchart, Kuninori
   Morimoto, Wolfram Sang and Magnus Damm.
 
 - Cleanups and refactorings of the nVidia Tegra driver from
   Stepgen Warren.
 
 - The Exynos driver now supports the Exynos3250 SoC.
 
 - Intel BayTrail updates from Jin Yao, Mika Westerberg.
 
 - The MVEBU driver now supports the Orion5x SoC
   variants, which is part of the effort of getting rid of
   the old Marvell kludges in arch/arm/mach-orion5x
 
 - Rockchip driver updates from Heiko Stuebner.
 
 - A ton of cleanups and janitorial patches from Axel Lin.
 
 - Some minor fixes and improvements here and there.
