…el/git/linusw/linux-pinctrl

Pull pin control updates from Linus Walleij:
 "This is the bulk of the pin control changes for the v5.9 kernel
  series:

  Core changes:

   - The GPIO patch "gpiolib: Introduce for_each_requested_gpio_in_range()
     macro" was put in an immutable branch and merged into the pinctrl
     tree as well. We see these changes also here.

   - Improved debug output for pins used as GPIO.

  New drivers:

   - Ocelot Sparx5 SoC driver.

   - Intel Emmitsburg SoC subdriver.

   - Intel Tiger Lake-H SoC subdriver.

   - Qualcomm PM660 SoC subdriver.

   - Renesas SH-PFC R8A774E1 subdriver.

  Driver improvements:

   - Linear improvement and cleanups of the Intel drivers for
     Cherryview, Lynxpoint, Baytrail etc. Improved locking among other
     things.

   - Renesas SH-PFC has added support for RPC pins, groups, and
     functions to r8a77970 and r8a77980.

   - The newere Freescale (now NXP) i.MX8 pin controllers have been
     modularized. This is driven by the Google Android GKI initiative I
     think.

   - Open drain support for pins on the Qualcomm IPQ4019.

   - The Ingenic driver can handle both edges IRQ detection.

   - A big slew of documentation fixes all over the place.

   - A few irqchip template conversions by yours truly.

+title: Ingenic SoCs pin controller devicetree bindings
+
+description: >
+  Please refer to pinctrl-bindings.txt in this directory for details of the
+  common pinctrl bindings used by client devices, including the meaning of the
+  phrase "pin configuration node".
+
+  For the Ingenic SoCs, pin control is tightly bound with GPIO ports. All pins
+  may be used as GPIOs, multiplexed device functions are configured within the
+  GPIO port configuration registers and it is typical to refer to pins using the
+  naming scheme "PxN" where x is a character identifying the GPIO port with
+  which the pin is associated and N is an integer from 0 to 31 identifying the
+  pin within that GPIO port. For example PA0 is the first pin in GPIO port A,
+  and PB31 is the last pin in GPIO port B. The JZ4740, the X1000 and the X1830
+  contains 4 GPIO ports, PA to PD, for a total of 128 pins. The JZ4760, the
+  JZ4770 and the JZ4780 contains 6 GPIO ports, PA to PF, for a total of 192
+  pins.
