Merge tag 'pinctrl-v5.9-1' 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 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. * tag 'pinctrl-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (107 commits) dt-bindings: pinctrl: add bindings for MediaTek MT6779 SoC pinctrl: stmfx: Use irqchip template pinctrl: amd: Use irqchip template pinctrl: mediatek: fix build for tristate changes pinctrl: samsung: Use bank name as irqchip name pinctrl: core: print gpio in pins debugfs file pinctrl: mediatek: add mt6779 eint support pinctrl: mediatek: add pinctrl support for MT6779 SoC pinctrl: mediatek: avoid virtual gpio trying to set reg pinctrl: mediatek: update pinmux definitions for mt6779 pinctrl: stm32: use the hwspin_lock_timeout_in_atomic() API pinctrl: mcp23s08: Use irqchip template pinctrl: sx150x: Use irqchip template dt-bindings: ingenic,pinctrl: Support pinmux/pinconf nodes pinctrl: intel: Add Intel Emmitsburg pin controller support pinctl: ti: iodelay: Replace HTTP links with HTTPS ones Revert "gpio: omap: handle pin config bias flags" pinctrl: single: Use fallthrough pseudo-keyword pinctrl: qcom: spmi-gpio: Use fallthrough pseudo-keyword pinctrl: baytrail: Use fallthrough pseudo-keyword ...

+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.
