git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "No core changes this time. Just new driver code and improvements! New drivers: - New driver for the Broadcom BCM4908 SoC. - New subdriver for Tesla FSD (Full Self Driving) SoC, a derivative of the Samsung Exynos pin control driver. - New driver for the Amlogic Meson S4 SoC. - New driver for the Sunplus SP7021 SoC. - New driver for the Microsemi Ocelot family ServalT SoC. - New subdriver for Intel Alder Lake-M SoC. - New subdriver for Intel Ice Lake-N SoC, including PCH support. - New subdriver for Renesas R8A779F0 SoC. - New subdriver for Mediatek MT8186 SoC. - New subdriver for NXP Freescale i.MX93 SoC. - New driver for Nuvoton WPCM450 SoC. - New driver for Qualcomm SC8280XP SoC. Improvements: - Wakeup support on Samsung Exynos850 and ExynosAutov9. - Serious and voluminous maintenance cleanup and refactoring in the Renesas drivers. Mainly sharing similar data between the different SoC subdrivers. - Qualcomm SM8450 EGPIO support. - Drive strength support on the Mediatek MT8195. - Add some missing groups and functions to the Ralink RT2880" * tag 'pinctrl-v5.18-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (188 commits) pinctrl: mediatek: common-v1: fix semicolon.cocci warnings pinctrl: nuvoton: wpcm450: Fix build error without OF pinctrl: qcom-pmic-gpio: Add support for pm8450 dt-bindings: pinctrl: aspeed: Update gfx node in example dt-bindings: pinctrl: rt2880: add missing pin groups and functions pinctrl: ingenic: Fix regmap on X series SoCs pinctrl: nuvoton: Fix return value check in wpcm450_gpio_register() pinctrl: nuvoton: wpcm450: off by one in wpcm450_gpio_register() pinctrl: nuvoton: wpcm450: select GENERIC_PINCTRL_GROUPS pinctrl: nuvoton: Fix sparse warning pinctrl: mediatek: mt8186: Account for probe refactoring pinctrl: mediatek: common-v1: Commonize spec_ies_smt_set callback pinctrl: mediatek: common-v1: Commonize spec_pupd callback pinctrl: mediatek: common-v1: Use common probe function pinctrl: mediatek: common-v1: Add common probe function pinctrl: mediatek: paris: Unify probe function by using OF match data pinctrl/rockchip: Add missing of_node_put() in rockchip_pinctrl_probe pinctrl: nomadik: Add missing of_node_put() in nmk_pinctrl_probe pinctrl: berlin: fix error return code of berlin_pinctrl_build_state() pinctrl: qcom: Introduce sc8280xp TLMM driver ...
2022-03-24pinctrl: nuvoton: Fix sparse warningLinus Walleij1-1/+1
Sparse complains: drivers/pinctrl/nuvoton/pinctrl-wpcm450.c:626:9: sparse: sparse: obsolete array initializer, use C99 syntax This is because no equal sign is between the array index and the assignments, in the macro.

2022-02-11pinctrl: nuvoton: npcm7xx: Rename DS() macro to DSTR()Jonathan Neuschäfer1-79/+79
The name "DS" is defined in arch/x86/um/shared/sysdep/ptrace_64.h, which results in a compiler warning when build-testing on ARCH=um. Rename this driver's "DS" macro to DSTR so avoid this collision.

When compile-testing on 64-bit architectures, GCC complains about the mismatch of types between the %d format specifier and value returned by ARRAY_LENGTH(). Use %zu, which is correct everywhere.

2022-02-10pinctrl: npcm: Fix broken references to chip->parent_deviceMarc Zyngier1-13/+12
The npcm driver has a bunch of references to the irq_chip parent_device field, but never sets it. Fix it by fishing that reference from somewhere else, but it is obvious that these debug statements were never used. Also remove an unused field in a local data structure.

Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq().

2020-09-30pinctrl: nuvoton: npcm7xx: Constify static ops structsRikard Falkeborn1-3/+3
The only usage of these structs is to assign their address to various ops fields in the pinctrl_desc struct, which are const pointers. Make them const to allow the compiler to put them in read-only memory.

2019-10-01pinctrl: nuvoton: npcm7xx: Pass irqchip when adding gpiochipLinus Walleij1-16/+16
We need to convert all old gpio irqchips to pass the irqchip setup along when adding the gpio_chip. For more info see drivers/gpio/TODO. For chained irqchips this is a pretty straight-forward conversion.

2018-12-06pinctrl: nuvoton: check for devm_kasprintf() failureNicholas Mc Guire1-0/+3
devm_kasprintf() may return NULL on failure of internal allocation thus the assignment to .label is not safe if not checked. On error npcm7xx_gpio_of() returns negative values so -ENOMEM in the (unlikely) failure case of devm_kasprintf() should be fine here.
