Pull pin control updates from Linus Walleij: "Pin control bulk changes for the v4.11 kernel cycle. Core changes: - Switch the generic pin config argument from 16 to 24 bits, only use 8 bits for the configuration type. We might need to encode more information about a certain setting than we need to encode different generic settings. - Add a cross-talk API to the pin control GPIO back-end, utilizing pinctrl_gpio_set_config() from GPIO drivers that want to set up a certain pin configuration in the back-end. This also includes the .set_config() refactoring of the GPIO chips, so that they pass a generic configuration for things like debouncing and single ended (typically open drain). This change has also been merged in an immutable branch to the GPIO tree. - Take hogs with a delayed work, so that we finalize probing a pin controller before trying to get any hogs. - For pin controllers putting all group and function definitions into the device tree, we now have generic code to deal with this and it is used in two drivers so far. - Simplifications of the pin request conflict check. - Make dt_free_map() optional. Updates to drivers: - pinctrl-single now use the generic helpers to generate dynamic group and function tables from the device tree. - Texas Instruments IOdelay configuration driver add-on to pinctrl-single. - i.MX: use radix trees to store groups and functions, use the new generic group and function helpers to manage them. - Intel: add support for hardware debouncing and 1K pull-down. New subdriver for the Gemini Lake SoC. - Renesas SH-PFC: drive strength and bias support, CAN bus muxing, MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791. - Aspeed: use syscon cross-dependencies to set up related bits in the LPC host controller and display controller. - Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs. Add banks Y, Z, AA, AB and AC. - AMD: support additional GPIO. - STM32: set this controller to strict muxing mode. STM32H743 MCU support. - Allwinner sunxi: deep simplifications on how to support subvariants of SoCs without adding to much SoC-specific data for each subvariant, especially for sun5i variants. New driver for V3s SoCs. New driver for the H5 SoC. Support A31/A31s variants with the new variant framework. - Mvebu: simplifications to use a MMIO and regmap abstraction. New subdrivers for the 98DX3236, 98DX5241 SoCs. - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC driver to access regmaps. Add infrastructure for pin-bank retention control. Clean out the pin retention control from arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in the Samsung pin control driver(s). - Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin. - Qualcomm: use raw spinlock variants: this makes the qualcomm driver realtime-safe" * tag 'pinctrl-v4.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (111 commits) pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data() pinctrl: intel: unlock on error in intel_config_set_pull() pinctrl: berlin: make bool drivers explicitly non-modular pinctrl: spear: make bool drivers explicitly non-modular pinctrl: mvebu: make bool drivers explicitly non-modular pinctrl: sunxi: make sun5i explicitly non-modular pinctrl: sunxi: Remove stray printk call in sun5i driver's probe function pinctrl: samsung: mark PM functions as __maybe_unused pinctrl: sunxi: Remove redundant A31s pinctrl driver pinctrl: sunxi: Support A31/A31s with pinctrl variants pinctrl: Amend bindings for STM32 pinctrl pinctrl: Add STM32 pinctrl driver DT bindings pinctrl: stm32: Add STM32H743 MCU support include: dt-bindings: Add STM32H7 pinctrl DT defines gpio: aspeed: Remove dependence on GPIOF_* macros pinctrl: stm32: fix bad location of gpiochip_lock_as_irq drivers: pinctrl: add driver for Allwinner H5 SoC pinctrl: intel: Add Intel Gemini Lake pin controller support pinctrl: intel: Add support for 1k additional pull-down pinctrl: intel: Add support for hardware debouncer ...

pinctrl: berlin: make bool drivers explicitly non-modular

2017-02-13T13:25:55+00:00

None of the Kconfigs for any of these drivers are tristate, meaning that they currently are not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.

pinctrl: Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map

2016-04-01T13:06:36+00:00

Rename pinctrl_utils_dt_free_map to pinctrl_utils_free_map, since it does not depend on device tree despite the current name. This will enforce a consistent naming in pinctr-utils.c and will make it clear it can be called from outside device tree (e.g. from ACPI handling code).

pinctrl: berlin: guard sub-directory with CONFIG_PINCTRL_BERLIN

pinctrl: berlin: fix BG2CD field widths

2015-10-16T14:42:48+00:00

The previous register layout was incorrect, many of the fields having fewer bits than were needed to represent all their modes. The new layout is taken from the bootloader source of a BG2CD device. Signed-off-by: Thomas Hebb Acked-by: Sebastian Hesselbarth Signed-off-by: Linus Walleij
