Pins that (1) can be configured as either GPIO or a single peripheral
function, and (2) that don't need configuration in an IPSRx register,
should still be listed in the pinmux_data[] array.
Else selecting the peripheral function fails with e.g.:
sh-pfc e6060000.pfc: cannot locate data/mark enum_id for mark 1281
(mark 1281 is MSIOF0_SCK_MARK).

The name .dev in a struct is normally reserved for a struct device
that is let us say a superclass to the thing described by the struct.
struct gpio_chip stands out by confusingly using a struct device *dev
to point to the parent device (such as a platform_device) that
represents the hardware. As we want to give gpio_chip:s real devices,
this is not working. We need to rename this member to parent.
This was done by two coccinelle scripts, I guess it is possible to
combine them into one, but I don't know such stuff. They look like
this:
@@
struct gpio_chip *var;
@@
-var->dev
+var->parent
and:
@@
struct gpio_chip var;
@@
-var.dev
+var.parent
and:
@@
struct bgpio_chip *var;
@@
-var->gc.dev
+var->gc.parent
Plus a few instances of bgpio that I couldn't figure out how
to teach Coccinelle to rewrite.
This patch hits all over the place, but I *strongly* prefer this
solution to any piecemal approaches that just exercise patch
mechanics all over the place. It mainly hits drivers/gpio and
drivers/pinctrl which is my own backyard anyway.

Merge tag 'gpio-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for the v4.4 development cycle.
The only changes hitting outside drivers/gpio are in the pin control
subsystem and these seem to have settled nicely in linux-next.
Development mistakes and catfights are nicely documented in the
reverts as you can see. The outcome of the ABI fight is that we're
working on a chardev ABI for GPIO now, where hope to show results for
the v4.5 kernel.
Summary of changes:
GPIO core:
- Define and handle flags for open drain/open collector and open
source/open emitter, also know as "single-ended" configurations.
- Generic request/free operations that handle calling out to the
(optional) pin control backend.
- Some refactoring related to an ABI change that did not happen, yet

- Added a real-time compliance checklist. Many GPIO chips have

- Restructure, fix and clean up Kconfig menus a bit.

- New driver for AMD Promony.
- New driver for ACCES 104-IDIO-16, a port-mapped I/O card,

v4.4 kernel development cycle:
Infrastructure:
- Doug Anderson wrote a patch adding an "init" state
different from the "default" state for pin control
state handling in the core framework. This is applied
before the driver's probe() call if defined and takes
precedence over "default". If both are defined, "init"
will be applied *before* probe() and "default" will be
applied *after* probe().
Significant subdriver improvements:
- SH PFC is switched to getting GPIO ranges from the
device tree ranges property on DT platforms.
- Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all
modernized.
- Got rid of SH PFC hardcoded IRQ numbers.
- Allwinner sunxi external interrupt through the "r"
controller.
- Moved the Cygnus driver to use DT-provided GPIO
ranges.
New drivers:
- Atmel PIO4 pin controller for the SAMA4D2 family
New subdrivers:
- Rockchip RK3036 subdriver
- Renesas SH PFC R8A7795 subdriver
- Allwinner sunxi A83T PIO subdriver
- Freescale i.MX7d iomux lpsr subdriver
- Marvell Berlin BG4CT subdriver
- SiRF Atlas 7 step B SoC subdriver

Merge tag 'pinctrl-v4.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the big bulk of pin control changes for the v4.4 kernel
development cycle. Development pace is high in pin control again this
merge window. 28 contributors, 83 patches.
It hits a few sites outside the pin control subsystem:
- Device tree bindings in Documentation (as usual)
- MAINTAINERS
- drivers/base/* for the "init" state handling by Doug Anderson.
This has been ACKed by Greg.
- drivers/usb/renesas_usbhs/rcar2.c, for a dependent Renesas change
in the USB subsystem. This has been ACKed by both Greg and Felipe.
- arch/arm/boot/dts/sama5d2.dtsi - this should ideally have gone
through the ARM SoC tree but ended up here.
This time I am using Geert Uytterhoeven as submaintainer for SH PFC
since the are three-four people working in parallel with new Renesas
ASICs.
Summary of changes:
Infrastructure:
- Doug Anderson wrote a patch adding an "init" state different from
the "default" state for pin control state handling in the core
framework. This is applied before the driver's probe() call if
defined and takes precedence over "default". If both are defined,
"init" will be applied *before* probe() and "default" will be
applied *after* probe().
Significant subdriver improvements:
- SH PFC is switched to getting GPIO ranges from the device tree
ranges property on DT platforms.
- Got rid of CONFIG_ARCH_SHMOBILE_LEGACY, we are all modernized.
- Got rid of SH PFC hardcoded IRQ numbers.
- Allwinner sunxi external interrupt through the "r" controller.
- Moved the Cygnus driver to use DT-provided GPIO ranges.
New drivers:
- Atmel PIO4 pin controller for the SAMA4D2 family
New subdrivers:
- Rockchip RK3036 subdriver
- Renesas SH PFC R8A7795 subdriver
- Allwinner sunxi A83T PIO subdriver
- Freescale i.MX7d iomux lpsr subdriver
- Marvell Berlin BG4CT subdriver
- SiRF Atlas 7 step B SoC subdriver
- Intel Broxton SoC subdriver
Apart from this, the usual slew if syntactic and semantic fixes"
