GPIO management is pretty simple and is part of the same IP than the pin controller for the Armada 37xx SoCs. This patch adds the GPIO support to the pinctrl-armada-37xx.c file, it also allows sharing common functions between the gpio and the pinctrl drivers.

2017-05-31pinctrl: armada-37xx: Add pin controller support for Armada 37xxGregory CLEMENT
The Armada 37xx SoC come with 2 pin controllers: one on the south bridge (managing 28 pins) and one on the north bridge (managing 36 pins). At the hardware level the controller configure the pins by group and not pin by pin. This constraint is reflected in the design of the driver: only the group related functions are implemented.

This driver uses Generic Pinctrl framework and is compatible with the Linux driver for ast2500: it uses the same device tree configuration.

2017-04-27pinctrl: Kconfig: sort pinctrl config options to prevent future clutterPhilipp Tomsich
This originally started out as "pinctrl: Kconfig: reorder to keep Rockchip options together" and tried to keep the Rockchip-related config options together. However, we now rewrite all chip-specific driver selections to start with CONFIG_PINCTRL_ (with the inadvertent changes to related Makefiles) and sort those alphabetically. And as this already means touching most of the file, we also reformat the help text to not exceed 80 characters (but make full use of those 80 characters).

2017-03-16dm: allow limiting pre-reloc markings to spl or tplHeiko Stübner
Right now the u-boot,dm-pre-reloc flag will make each marked node always appear in both spl and tpl. But systems needing an additional tpl might have special constraints for each, like the spl needing to be very tiny. So introduce two additional flags to mark nodes for only spl or tpl environments and introduce a function dm_fdt_pre_reloc to automate the necessary checks in code instances checking for pre-relocation flags. The behaviour of the original flag stays untouched and still marks a node for both spl and tpl.

2016-10-18pinctrl: uniphier: fix unused-const-variable warnings for GCC 6.xMasahiro Yamada
Marek reports warnings in UniPhier pinctrl drivers when compiled by GCC 6.x, like: drivers/pinctrl/uniphier/pinctrl-uniphier-ld20.c:58:18: warning: 'usb3_muxvals' defined but not used [-Wunused-const-variable=] static const int usb3_muxvals[] = {0, 0}; ^~~~~~~~~~~~ My intention here is to compile minimum set of pin data for SPL to save memory footprint, but GCC these days is clever enough to notice unused data arrays. We can fix it by sprinkling around __maybe_unused on those arrays, but I did not do that because they are counterparts of the pinctrl drivers in Linux. All the pin data were just copy-pasted from Linux and are kept in sync for maintainability. I chose a bit tricky way to fix the issue; calculate ARRAY_SIZE of *_pins and *_muxvals and set their sum to an unused struct member. This trick will satisfy GCC because the data arrays are used anyway, but such data arrays will be dropped from the final binary because the pointers to them are not used.
