Merge tag 'pinctrl-v4.15-1' of 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 ...
