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"
