Pull pin control updates from Linus Walleij: "Mostly drivers! Nothing special: some new Qualcomm chips as usual, and the new NXP S32 and nVidia BlueField-3. Core changes: - Make a lot of pin controllers with GPIO and irqchips immutable, i.e. not living structs, but const structs. This is driving a changed initiated by the irqchip maintainers. New drivers: - New driver for the NXP S32 SoC pin controller - As part of a thorough cleanup and restructuring of the Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were folded into the Mediatek directory and the family is renamed "mtmips". The Ralink chips live on as Mediatek MIPS family where new variants can be added. As part of this work also the device tree bindings were reworked. - New subdriver for the Qualcomm SM7150 SoC. - New subdriver for the Qualcomm IPQ9574 SoC. - New driver for the nVidia BlueField-3 SoC. - Support for the Qualcomm PMM8654AU mixed signal circuit GPIO. - Support for the Qualcomm PMI632 mixed signal circuit GPIO. Improvements: - Add some missing pins and generic cleanups on the Renesas r8a779g0 and r8a779g0 pin controllers. Generic Renesas extension for power source selection on several SoCs. - Misc cleanups for the Atmel AT91 and AT91-PIO4 pin controllers - Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi driver. - Several device tree binding cleanups as the binding YAML syntax is solidifying" * tag 'pinctrl-v6.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (153 commits) pinctrl-bcm2835.c: fix race condition when setting gpio dir dt-bindings: pinctrl: qcom,sm8150: Drop duplicate function value "atest_usb2" dt-bindings: pinctrl: qcom: Add few missing functions pinctrl: qcom: spmi-gpio: Add PMI632 support dt-bindings: pinctrl: qcom,pmic-gpio: add PMI632 pinctrl: wpcm450: select MFD_SYSCON pinctrl: qcom ssbi-gpio: Convert to immutable irq_chip pinctrl: qcom ssbi-mpp: Convert to immutable irq_chip pinctrl: qcom spmi-mpp: Convert to immutable irq_chip pinctrl: plgpio: Convert to immutable irq_chip pinctrl: pistachio: Convert to immutable irq_chip pinctrl: pic32: Convert to immutable irq_chip pinctrl: sx150x: Convert to immutable irq_chip pinctrl: stmfx: Convert to immutable irq_chip pinctrl: st: Convert to immutable irq_chip pinctrl: mcp23s08: Convert to immutable irq_chip pinctrl: equilibrium: Convert to immutable irq_chip pinctrl: npcm7xx: Convert to immutable irq_chip pinctrl: armada-37xx: Convert to immutable irq_chip pinctrl: nsp: Convert to immutable irq_chip ...
