2020-09-15dt-bindings: pinctrl: sh-pfc: Convert to json-schemaGeert Uytterhoeven1-188/+0
Convert the Renesas Pin Function Controller (PFC) Device Tree binding documentation to json-schema. Document missing properties. Drop deprecated and obsolete #gpio-range-cells property. Update the example to match reality. Drop consumer examples, as they do not belong here.

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 ...

2013-12-13sh-pfc: Support GPIO to IRQ mapping specified IRQ resourcesLaurent Pinchart1-0/+14
On non-DT platforms IRQ controllers associated with the GPIOs have a fixed IRQ base value known at compile time. The sh-pfc driver translates GPIO number to IRQ numbers using a hardcoded table. This mechanism breaks on DT platforms, as the IRQ base values are dynamic in that case. Fix this by specifying IRQs associated with GPIOs in IRQ resources, populated automatically from the device tree. When IRQ resources are specified the driver requires one IRQ resource per GPIO able to generate an interrupt, and uses the translation table to compute the IRQ resource offset instead of the IRQ number.
