git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes, nothing too exciting about this. Some changes hit arch/sh and arch/arm but are well isolated and acknowledged by the respective arch maintainers. Core changes: - Dropped the chained IRQ setup callback into GPIOLIB as we got rid of the last users of that in this changeset. New drivers: - New driver for Ingenic X1830. - New driver for Freescale i.MX8MP. Driver enhancements: - Fix all remaining Intel drivers to pass their IRQ chips along with the GPIO chips. - Intel Baytrail allocates its irqchip dynamically. - Intel Lynxpoint is thoroughly rewritten and modernized. - Aspeed AST2600 pin muxing and configuration is much improved. - Qualcomm SC7180 functions are updated and wakeup interrupt map is provided. - A whole slew of Renesas SH-PFC cleanups and improvements. - Fix up the Intel DT bindings to use the generic YAML DT bindings schema (a first user of this)" * tag 'pinctrl-v5.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (99 commits) pinctrl: madera: Remove extra blank line pinctrl: qcom: Don't lock around irq_set_irq_wake() pinctrl: mvebu: armada-37xx: use use platform api gpio: Drop the chained IRQ handler assign function pinctrl: freescale: Add i.MX8MP pinctrl driver support dt-bindings: imx: Add pinctrl binding doc for i.MX8MP pinctrl: tigerlake: Tiger Lake uses _HID enumeration pinctrl: sunrisepoint: Add Coffee Lake-S ACPI ID pinctrl: iproc: Use platform_get_irq_optional() to avoid error message pinctrl: dt-bindings: Fix some errors in the lgm and pinmux schema pinctrl: intel: Pass irqchip when adding gpiochip pinctrl: intel: Add GPIO <-> pin mapping ranges via callback pinctrl: baytrail: Replace WARN with dev_info_once when setting direct-irq pin to output pinctrl: baytrail: Do not clear IRQ flags on direct-irq enabled pins pinctrl: sunrisepoint: Add missing Interrupt Status register offset pinctrl: sh-pfc: Split R-Car H3 support in two independent drivers pinctrl: artpec6: fix __iomem on reg in set pinctrl: ingenic: Use devm_platform_ioremap_resource() pinctrl: ingenic: Factorize irq_set_type function pinctrl: ingenic: Remove duplicated ingenic_chip_info structures ...
2020-01-23gpio: Drop the chained IRQ handler assign functionLinus Walleij1-2/+1
gpiochip_set_chained_irqchip() would assign a chained handler to a GPIO chip. We now populate struct gpio_irq_chip for all chained GPIO irqchips so drop this function.

2019-12-11gpio: xgs-iproc: remove __exit annotation for iproc_gpio_removeArnd Bergmann1-1/+1
When built into the kernel, the driver causes a link problem: `iproc_gpio_remove' referenced in section `.data' of drivers/gpio/gpio-xgs-iproc.o: defined in discarded section `.exit.text' of drivers/gpio/gpio-xgs-iproc.o Remove the incorrect annotation.

2019-11-07gpio: xgs-iproc: Fix section mismatch on device tree match tableMark Brown1-1/+1
The table of devicetree identifiers is annotated as __initconst indicating that it can be discarded after kernel boot but it is referenced from the driver struct which has no init annotation leading to a linker warning: WARNING: vmlinux.o(.data+0x82d58): Section mismatch in reference from the variable bcm_iproc_gpio_driver to the variable .init.rodata:bcm_iproc_gpio_of_match The variable bcm_iproc_gpio_driver references the variable __initconst bcm_iproc_gpio_of_match Since drivers can be probed after init the lack of annotation on the driver struct is correct so remove the annotation from the match table.

2019-10-29gpio: Add xgs-iproc driverChris Packham1-0/+321
This driver supports the Chip Common A GPIO controller present on a number of Broadcom switch ASICs with integrated SoCs. The controller is similar to the pinctrl-nsp-gpio and pinctrl-iproc-gpio blocks but different enough that a separate driver is required. This has been ported from Broadcom's XLDK 5.0.3 retaining only the CCA support (pinctrl-iproc-gpio covers CCB).
