Other than that it is business as usual. Core changes: - Add PINCTRL_PINGROUP() helper macro (and use it in the AMD driver). New drivers: - Intel Meteor Lake support. - Reneasas RZ/V2M and r8a779g0 (R-Car V4H). - AXP209 variants AXP221, AXP223 and AXP809. - Qualcomm MSM8909, PM8226, PMP8074 and SM6375. - Allwinner D1. Improvements: - Proper pin multiplexing in the AMD driver. - Mediatek MT8192 can use generic drive strength and pin bias, then fixes on top plus some I2C pin group fixes. - Have the Allwinner Sunplus SP7021 use the generic DT schema and make interrupts optional. - Handle Qualcomm SC7280 ADSP. - Handle Qualcomm MSM8916 CAMSS GP clock muxing. - High impedance bias on ZynqMP. - Serialize StarFive access to MMIO. - Immutable gpiochip for BCM2835, Ingenic, Qualcomm SPMI GPIO" * tag 'pinctrl-v6.0-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (117 commits) dt-bindings: pinctrl: qcom,pmic-gpio: add PM8226 constraints pinctrl: qcom: Make PINCTRL_SM8450 depend on PINCTRL_MSM pinctrl: qcom: sm8250: Fix PDC map pinctrl: amd: Fix an unused variable dt-bindings: pinctrl: mt8186: Add and use drive-strength-microamp dt-bindings: pinctrl: mt8186: Add gpio-line-names property ARM: dts: imxrt1170-pinfunc: Add pinctrl binding header pinctrl: amd: Use unicode for debugfs output pinctrl: amd: Fix newline declaration in debugfs output pinctrl: at91: Fix typo 'the the' in comment dt-bindings: pinctrl: st,stm32: Correct 'resets' property name pinctrl: mvebu: Missing a blank line after declarations. pinctrl: qcom: Add SM6375 TLMM driver dt-bindings: pinctrl: Add DT schema for SM6375 TLMM dt-bindings: pinctrl: mt8195: Use drive-strength-microamp in examples Revert "pinctrl: qcom: spmi-gpio: make the irqchip immutable" pinctrl: imx93: Add MODULE_DEVICE_TABLE() pinctrl: sunxi: Add driver for Allwinner D1 pinctrl: sunxi: Make some layout parameters dynamic pinctrl: sunxi: Refactor register/offset calculation ...

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 ...

After commit 26d8cde5260b ("pinctrl: freescale: imx: add shared input select reg support"). i.MX7D has two iomux controllers iomuxc and iomuxc-lpsr which share select_input register for daisy chain settings. If use 'devm_of_iomap()', when probe the iomuxc-lpsr, will call devm_request_mem_region() for the region <0x30330000-0x3033ffff> for the first time. Then, next time when probe the iomuxc, API devm_platform_ioremap_resource() will also use the API devm_request_mem_region() for the share region <0x30330000-0x3033ffff> again, then cause issue, log like below: [ 0.179561] imx7d-pinctrl 302c0000.iomuxc-lpsr: initialized IMX pinctrl driver [ 0.191742] imx7d-pinctrl 30330000.pinctrl: can't request region for resource [mem 0x30330000-0x3033ffff] [ 0.191842] imx7d-pinctrl: probe of 30330000.pinctrl failed with error -16 Fixes: ba403242615c ("pinctrl: freescale: imx: Use 'devm_of_iomap()' to avoid a resource leak in case of error in 'imx_pinctrl_probe()'") Signed-off-by: Haibo Chen <haibo.chen@nxp.com> Reviewed-by: Dong Aisheng <aisheng.dong@nxp.com> Link: https://lore.kernel.org/r/1591673223-1680-1-git-send-email-haibo.chen@nxp.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

This will affect how the system power management is handled: a pin controller will not suspend before all of its consumers have been suspended. This was necessary for the ST Microelectronics STMFX expander and need to be tested on other systems as well: it makes sense to make this default in the long run. Right now it is opt-in per driver. - Drive strength can be specified in microamps. With decreases in silicon technology, milliamps isn't granular enough, let's make it possible to select drive strengths in microamps. Right now the Meson (AMlogic) driver needs this.

Driver improvements: - The Bitmain BM1880 driver now supports pin config in addition to muxing. - The Qualcomm drivers can now reserve some GPIOs as taken aside and not usable for users. This is used in ACPI systems to take out some GPIO lines used by the BIOS so that noone else (neither kernel nor userspace) will play with them by mistake and crash the machine. - A slew of refurbishing around the Aspeed drivers (board management controllers for servers) in preparation for the new Aspeed AST2600 SoC. - A slew of improvements over the SH PFC drivers as usual. - Misc cleanups and fixes" * tag 'pinctrl-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (106 commits) pinctrl: aspeed: Strip moved macros and structs from private header pinctrl: aspeed: Fix missed include pinctrl: baytrail: Use GENMASK() consistently pinctrl: baytrail: Re-use data structures from pinctrl-intel.h pinctrl: baytrail: Use defined macro instead of magic in byt_get_gpio_mux() pinctrl: qcom: Add SM8150 pinctrl driver dt-bindings: pinctrl: qcom: Add SM8150 pinctrl binding dt-bindings: pinctrl: qcom: Document missing gpio nodes pinctrl: aspeed: Add implementation-related documentation pinctrl: aspeed: Split out pinmux from general pinctrl pinctrl: aspeed: Clarify comment about strapping W1C pinctrl: aspeed: Correct comment that is no longer true MAINTAINERS: Add entry for ASPEED pinctrl drivers dt-bindings: pinctrl: aspeed: Convert AST2500 bindings to json-schema dt-bindings: pinctrl: aspeed: Convert AST2400 bindings to json-schema dt-bindings: pinctrl: aspeed: Split bindings document in two pinctrl: qcom: Add irq_enable callback for msm gpio pinctrl: madera: Fixup SPDX headers pinctrl: qcom: sdm845: Fix CONFIG preprocessor guard pinctrl: tegra: Add bitmask support for parked bits ...
