git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v5.11 kernel. Drivers, drivers and drivers. Not a single core change. Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot SoCs. As part of the modularization attempt, I applied one patch affecting the firmware subsystem as a functional (not syntactic/semantic) dependency and then it blew up in our face, so I had to revert it, bummer. It will come in later, through that subsystem, I guess. New drivers: - New driver for the Microchip Serial GPIO "SGPIO". - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver. New subdrivers: - Intel Lakefield subdriver. - Intel Elkhart Lake subdriver. - Intel Alder Lake-S subdriver. - Qualcomm MSM8953 subdriver. - Qualcomm SDX55 subdriver. - Qualcomm SDX55 PMIC subdriver. - Ocelot Luton SoC subdriver. - Ocelot Serval SoC subdriver. Modularization: - The Meson driver can now be built as modules. - The Qualcomm driver(s) can now be built as modules. Incremental improvements: - The Intel driver now supports pin configuration for GPIO-related configurations. - A bunch of Renesas PFC drivers have been augmented with support for QSPI pins, groups and functions. - Non-critical fixes to the irq handling in the Allwinner Sunxi driver" * tag 'pinctrl-v5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (80 commits) pinctrl/spear: simplify the return expression of spear300_pinctrl_probe() pinctrl: mediatek: simplify the return expression of mtk_pinconf_bias_disable_set_rev1() dt-bindings: pinctrl: pinctrl-microchip-sgpio: Add irq support pinctrl: pinctrl-microchip-sgpio: Add irq support (for sparx5) pinctrl: qcom: Add sm8250 lpass lpi pinctrl driver dt-bindings: pinctrl: qcom: Add sm8250 lpass lpi pinctrl bindings pinctrl: qcom-pmic-gpio: Add support for pmx55 dt-bindings: pinctrl: qcom-pmic-gpio: Add pmx55 support pinctrl: pinctrl-microchip-sgpio: Mark some symbols with static keyword pinctrl: at91-pio4: Make PINCTRL_AT91PIO4 depend on HAS_IOMEM to fix build error pinctrl: mtk: Fix low level output voltage issue pinctrl: falcon: add missing put_device() call in pinctrl_falcon_probe() pinctrl: actions: pinctrl-s500: Constify s500_padinfo[] pinctrl: pinctrl-microchip-sgpio: Add OF config dependency pinctrl: pinctrl-microchip-sgpio: Add pinctrl driver for Microsemi Serial GPIO dt-bindings: pinctrl: Add bindings for pinctrl-microchip-sgpio driver pinctrl: at91-pio4: add support for fewer lines on last PIO bank pinctrl: sunxi: Always call chained_irq_{enter, exit} in sunxi_pinctrl_irq_handler pinctrl: sunxi: Mark the irq bank not found in sunxi_pinctrl_irq_handler() with WARN_ON pinctrl: sunxi: fix irq bank map for the Allwinner A100 pin controller ...

2020-09-15pinctrl: Rename sh-pfc to renesasGeert Uytterhoeven
The drivers/pinctrl/sh-pfc subdirectory was originally created to group pin control drivers for various Renesas SuperH and SH-Mobile platforms. However, the name "sh-pfc" no longer reflects its contents, as the directory now contains pin control drivers for Renesas SuperH, ARM32, and ARM64 SoCs. Hence rename the subdirectory from drivers/pinctrl/sh-pfc to drivers/pinctrl/renesas, and the related Kconfig symbol from PINCTRL_SH_PFC to PINCTRL_RENESAS. Rename the git branch in MAINTAINERS, too, for consistency. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/20200909131534.12897-3-geert+renesas@glider.be

2018-08-06pinctrl: ocelot: add support for interrupt controllerQuentin Schulz
This GPIO controller can serve as an interrupt controller as well on the GPIOs it handles. An interrupt is generated whenever a GPIO line changes and the interrupt for this GPIO line is enabled. This means that both the changes from low to high and high to low generate an interrupt. For some use cases, it makes sense to ignore the high to low change and not generate an interrupt. Such a use case is a line that is hold in a level high/low manner until the event holding the line gets acked. This can be achieved by making sure the interrupt on the GPIO controller side gets acked and masked only after the line gets hold in its default state, this is what's done with the fasteoi functions. Only IRQ_TYPE_EDGE_BOTH and IRQ_TYPE_LEVEL_HIGH are supported for now. Signed-off-by: Quentin Schulz <quentin.schulz@bootlin.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2018-06-05pinctrl: madera: Add driver for Cirrus Logic Madera codecsRichard Fitzgerald
These codecs have a variable number of I/O lines each of which is individually selectable to a wide range of possible functions. The functionality is slightly different from the traditional muxed GPIO since most of the functions can be mapped to any pin (and even the same function to multiple pins). Most pins have a dedicated "alternate" function that is only available on that pin. The alternate functions are usually a group of signals, though it is not always necessary to enable the full group, depending on the alternate function and how it is to be used. The mapping between alternate functions and GPIO pins varies between codecs depending on the number of alternate functions and available pins.

Add pinctrl driver for Actions Semi S900 SoC. The driver supports pinctrl, pinmux and pinconf functionalities through a range of registers common to both gpio driver and pinctrl driver. Pinmux functionality is available only for the pin groups while the pinconf functionality is available for both pin groups and individual pins.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.15 kernel cycle: Core: - The pin control Kconfig entry PINCTRL is now turned into a menuconfig option. This obviously has the implication of making the subsystem menu visible in menuconfig. This is happening because of two things: (a) Intel have started to deploy and depend on pin controllers in a way that is affecting users directly. This happens on the highly integrated laptop chipsets named after geographical places: baytrail, broxton, cannonlake, cedarfork, cherryview, denverton, geminilake, lewisburg, merrifield, sunrisepoint... It started a while back and now it is ever more evident that this is crucial infrastructure for x86 laptops and not an embedded obscurity anymore. Users need to be aware. (b) Pin control expanders on I2C and SPI that are arch-agnostic. Currently Semtech SX150X and Microchip MCP28x08 but more are expected. Users will have to be able to configure these in directly for their set-up. - Just go and select GPIOLIB now that we made sure that GPIOLIB is a very vanilla subsystem. Do not depend on it, if we need it, select it. - Exposing the pin control subsystem in menuconfig uncovered a bunch of obscure bugs that are now hopefully fixed, all more or less pertaining to Blackfin. - Unified namespace for cross-calls between pin control and GPIO. - New support for clock skew/delay generic DT bindings and generic pin config options for this. - Minor documentation improvements. Various: - The Renesas SH-PFC pin controller has evolved a lot. It seems Renesas are churning out new SoCs by the minute. - A bunch of non-critical fixes for the Rockchip driver. - Improve the use of library functions instead of open coding. - Support the MCP28018 variant in the MCP28x08 driver. - Static constifying" * tag 'pinctrl-v4.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (91 commits) pinctrl: gemini: Fix missing pad descriptions pinctrl: Add some depends on HAS_IOMEM pinctrl: samsung/s3c24xx: add CONFIG_OF dependency pinctrl: gemini: Fix GMAC groups pinctrl: qcom: spmi-gpio: Add pmi8994 gpio support pinctrl: ti-iodelay: remove redundant unused variable dev pinctrl: max77620: Use common error handling code in max77620_pinconf_set() pinctrl: gemini: Implement clock skew/delay config pinctrl: gemini: Use generic DT parser pinctrl: Add skew-delay pin config and bindings pinctrl: armada-37xx: Add edge both type gpio irq support pinctrl: uniphier: remove eMMC hardware reset pin-mux pinctrl: rockchip: Add iomux-route switching support for rk3288 pinctrl: intel: Add Intel Cedar Fork PCH pin controller support pinctrl: intel: Make offset to interrupt status register configurable pinctrl: sunxi: Enforce the strict mode by default pinctrl: sunxi: Disable strict mode for old pinctrl drivers pinctrl: sunxi: Introduce the strict flag pinctrl: sh-pfc: Save/restore registers for PSCI system suspend pinctrl: sh-pfc: r8a7796: Use generic IOCTRL register description ...
