Some of this is used as merge base for other trees so I better be early on the trigger. As can be seen from the diffstat the major changes are: - A big conversion of the AT91 pinctrl driver and the associated ACKed platform changes under arch/arm/max-at91 and its device trees. This has been coordinated with the AT91 maintainers to go in through the pinctrl tree. - A larger chunk of changes to the SPEAr drivers and the addition of the "plgpio" driver for the SPEAr as well. - The removal of the remnants of the Nomadik driver from the arch/arm tree and fusion of that into the Nomadik driver and platform data header files. - Some local movement in the Marvell MVEBU drivers, these now have their own subdirectory. - The addition of a chunk of code to gpiolib under drivers/gpio to register gpio-to-pin range mappings from the GPIO side of things. This has been requested by Grant Likely and is now implemented, it is particularly useful for device tree work. Then we have incremental updates all over the place, many of these are cleanups and fixes from Axel Lin who has done a great job of removing minor mistakes and compilation annoyances." * tag 'pinctrl-for-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (114 commits) ARM: mmp: select PINCTRL for ARCH_MMP pinctrl: Drop selecting PINCONF for MMP2, PXA168 and PXA910 pinctrl: pinctrl-single: Fix error check condition pinctrl: SPEAr: Update error check for unsigned variables gpiolib: Fix use after free in gpiochip_add_pin_range gpiolib: rename pin range arguments pinctrl: single: support gpio request and free pinctrl: generic: add input schmitt disable parameter pinctrl/u300/coh901: stop spawning pinctrl from GPIO pinctrl/u300/coh901: let the gpio_chip register the range pinctrl: add function to retrieve range from pin gpiolib: return any error code from range creation pinctrl: make range registration defer properly gpiolib: rename find_pinctrl_* gpiolib: let gpiochip_add_pin_range() specify offset ARM: at91: pm9g45: add mmc support ARM: at91: Animeo IP: add mmc support ARM: at91: dt: add mmc pinctrl for Atmel reference boards ARM: at91: dt: at91sam9: add mmc pinctrl support ARM: at91/dts: add nodes for atmel hsmci controllers for atmel boards ...

Each pin binds to one register. A lot of pins could be configured as gpio. GPIO range is defined as a child node of pinmux in .dtsi file. If those pins are with the same gpio function configuration in the pinmux register, they could be defined in the same GPIO range. For this new child node, two properties are used. reg = <the start of pinmux register in range, size of range> pinctrl-single,gpio: <gpio base in range, the gpio function of the range in the pinmux register> Signed-off-by: Haojian Zhuang <haojian.zhuang@gmail.com> Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a function to the pinctrl core to retrieve the GPIO range associated with a certain pin for a certain controller. This is needed when a pinctrl driver want to look up the corresponding struct gpio_chip for a certain pin. As the GPIO drivers can now create these ranges themselves, the pinctrl driver no longer knows about all its associated GPIO chips.

In cases like this there are actually just a few select registers that the pinctrl driver need to read/modify/write, and it turns out that no other driver is actually using these registers, so there are no concurrency issues whatsoever. So: don't let the location of the register range complicate things, just poke into these registers directly and skip a layer of indirection.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the platform data header for the Nomadik pin controller to <linux/platform_data/pinctrl-nomadik.h>. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
| | * | pinctrl/nomadik: allow to support several ranges per GPIO bankPatrice Chotard2012-10-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With DB8500 the number of GPIO chips = number GPIO bank = number of GPIO ranges. With DB8540, a new GPIO range configuration is used, some GPIO banks can have several GPIO ranges. For example, DB8540 GPIO bank0 (GPIO0 to GPIO32) have 2 GPIO ranges: - GPIO0 to GPIO17 : routed - GPIO18 to GPIO21 : hole - GPIO22 to GPIO28 : routed - GPIO29 to GPIO32 : hole Previously, during nmk_pinctrl_probe(), all GPIO ranges were parsed, as GPIO ranges are larger than the number of GPIO chips, a warning occurs. This commit allows each bank to have several GPIO ranges. Signed-off-by: Patrice Chotard <patrice.chotard@stericsson.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
