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 ...

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.9 kernel cycle. There is nothing too exciting in it, but a new macro that fixes a build failure on a minor ARM32 platform that appeared yesterday is part of it so we better merge it. Core changes: - Introduce the for_each_requested_gpio() macro to help in dependent code all over the place. Also patch a few locations to use it while we are at it. - Split out the sysfs code into its own file. - Split out the character device code into its own file, then make a set of refactorings and improvements to this code. We are setting the stage to revamp the userspace API a bit in the next cycle. - Fix a whole slew of kerneldoc that was wrong or missing. New drivers: - The PCA953x driver now supports the PCAL9535. Driver improvements: - A host of incremental modernizations and improvements to the PCA953x driver. - Incremental improvements to the Xilinx Zynq driver. - Some improvements to the GPIO aggregator driver. - I ran all over the place switching all threaded and other drivers requesting their own IRQ while using the core GPIO IRQ helpers to pass the GPIO irq chip as a template instead of calling the explicit set-up functions. Next merge window we may retire the old code altogether" * tag 'gpio-v5.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (97 commits) gpio: wcove: Request IRQ after all initialisation done gpio: crystalcove: Free IRQ on error path gpio: pca953x: Request IRQ after all initialisation done gpio: don't use same lockdep class for all devm_gpiochip_add_data users gpio: max732x: Use irqchip template gpio: stmpe: Move chip registration gpio: rcar: Use irqchip template gpio: regmap: fix type clash gpio: Correct kernel-doc inconsistency gpio: pci-idio-16: Use irqchip template gpio: pcie-idio-24: Use irqchip template gpio: 104-idio-16: Use irqchip template gpio: 104-idi-48: Use irqchip template gpio: 104-dio-48e: Use irqchip template gpio: ws16c48: Use irqchip template gpio: omap: improve coding style for pin config flags gpio: dln2: Use irqchip template gpio: sch: Add a blank line between declaration and code gpio: sch: changed every 'unsigned' to 'unsigned int' gpio: ich: changed every 'unsigned' to 'unsigned int' ...
2020-08-04pinctrl: stmfx: Use irqchip templateLinus Walleij
This makes the driver use the irqchip template to assign properties to the gpio_irq_chip instead of using the explicit calls to gpiochip_irqchip_add_nested() and gpiochip_set_nested_irqchip().

2020-07-23pinctrl: stm32: use the hwspin_lock_timeout_in_atomic() APIFabien Dessenne
Use the hwspin_lock_timeout_in_atomic() API which is the most appropriated here. Indeed: - hwspin_lock_() is called after spin_lock_irqsave() - the hwspin_lock_timeout() API relies on jiffies count which won't work if IRQs are disabled which is the case here.

2020-07-16pinctrl: qcom: Handle broken/missing PDC dual edge IRQs on sc7180Douglas Anderson
Depending on how you look at it, you can either say that: a) There is a PDC hardware issue (with the specific IP rev that exists on sc7180) that causes the PDC not to work properly when configured to handle dual edges. b) The dual edge feature of the PDC hardware was only added in later HW revisions and thus isn't in all hardware. Regardless of how you look at it, let's work around the lack of dual edge support by only ever letting our parent see requests for single edge interrupts on affected hardware. NOTE: it's possible that a driver requesting a dual edge interrupt might get several edges coalesced into a single IRQ. For instance if a line starts low and then goes high and low again, the driver that requested the IRQ is not guaranteed to be called twice. However, it is guaranteed that once the driver's interrupt handler starts running its first instruction that any new edges coming in will cause the interrupt to fire again. This is relatively commonplace for dual-edge gpio interrupts (many gpio controllers require software to emulate dual edge with single edge) so client drivers should be setup to handle it.

2020-07-16pinctrl: aspeed: Improve debug outputAndrew Jeffery
We need to iterate over each pin in a group for a function and disable higher priority mux configurations on the pin before finally muxing the relevant function's signal. With the current debug output it is hard to track what register output is relevant to which operation, so break up the actions in the debug output by providing some more context.
