Merge tag 'pinctrl-v5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control bulk updates from Linus Walleij: "Core changes: - New standard enumerator and corresponding device tree bindings for output impedance pin configuration. (Implemented and used in the Renesas rzg2l driver.) - Cleanup of Kconfig and Makefile to be somewhat orderly and alphabetic. New drivers: - Samsung Exynos 7885 pin controller. - Ocelot LAN966x pin controller. - Qualcomm SDX65 pin controller. - Qualcomm SM8450 pin controller. - Qualcomm PM8019, PM8226 and PM2250 pin controllers. - NXP/Freescale i.MXRT1050 pin controller. - Intel Thunder Bay pin controller. Enhancements: - Introduction of the string library helper function "kasprintf_strarray()" and subsequent use in Rockchip, ST and Armada pin control drivers, as well as the GPIO mockup driver. - The Ocelot pin controller has been extensively rewritten to use regmap and other modern kernel infrastructure. - The Microchip SGPIO driver has been converted to use regmap. - The SPEAr driver had been converted to use regmap. - Substantial cleanups and janitorial on the Apple pin control driver that was merged for v5.16. - Janitorial to remove of_node assignments in the GPIO portions that anyway get this handled in the GPIO core. - Minor cleanups and improvements in several pin controllers" * tag 'pinctrl-v5.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (98 commits) pinctrl: imx: fix assigning groups names dt-bindings: pinctrl: mt8195: add wrapping node of pin configurations pinctrl: bcm: ns: use generic groups & functions helpers pinctrl: imx: fix allocation result check pinctrl: samsung: Use platform_get_irq_optional() to get the interrupt pinctrl: Propagate firmware node from a parent device dt-bindings: pinctrl: qcom: Add SDX65 pinctrl bindings pinctrl: add one more "const" for generic function groups pinctrl: keembay: rework loops looking for groups names pinctrl: keembay: comment process of building functions a bit pinctrl: imx: prepare for making "group_names" in "function_desc" const ARM: dts: gpio-ranges property is now required pinctrl: aspeed: fix unmet dependencies on MFD_SYSCON for PINCTRL_ASPEED pinctrl: Get rid of duplicate of_node assignment in the drivers pinctrl-sunxi: don't call pinctrl_gpio_direction() pinctrl-bcm2835: don't call pinctrl_gpio_direction() pinctrl: bcm2835: Silence uninit warning pinctrl: Sort Kconfig and Makefile entries alphabetically pinctrl: Add Intel Thunder Bay pinctrl driver dt-bindings: pinctrl: Add bindings for Intel Thunderbay pinctrl driver ...

== Pin controller devices ==
-Required properties: See the pin controller driver specific documentation
-Optional properties:
-#pinctrl-cells: Number of pin control cells in addition to the index within the
- pin controller device instance
-
-pinctrl-use-default: Boolean. Indicates that the OS can use the boot default
- pin configuration. This allows using an OS that does not have a
- driver for the pin controller. This property can be set either
- globally for the pin controller or in child nodes for individual
- pin group control.
-
-Pin controller devices should contain the pin configuration nodes that client
-devices reference.
-
-For example:
-
- pincontroller {
- ... /* Standard DT properties for the device itself elided */
-
- state_0_node_a {
- ...
- };
- state_1_node_a {
- ...
- };
- state_1_node_b {
- ...
- };
- }
-
-The contents of each of those pin configuration child nodes is defined
-entirely by the binding for the individual pin controller device. There
-exists no common standard for this content. The pinctrl framework only
-provides generic helper bindings that the pin controller driver can use.
-
-The pin configuration nodes need not be direct children of the pin controller
-device; they may be grandchildren, for example. Whether this is legal, and
-whether there is any interaction between the child and intermediate parent
-nodes, is again defined entirely by the binding for the individual pin
-controller device.
