Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.17 kernel cycle: New drivers: - Nintendo Wii GameCube GPIO, known as "Hollywood" - Raspberry Pi mailbox service GPIO expander - Spreadtrum main SC9860 SoC and IEC GPIO controllers. Improvements: - Implemented .get_multiple() callback for most of the high-performance industrial GPIO cards for the ISA bus. - ISA GPIO drivers now select the ISA_BUS_API instead of depending on it. This is merged with the same pattern for all the ISA drivers and some other Kconfig cleanups related to this. Cleanup: - Delete the TZ1090 GPIO drivers following the deletion of this SoC from the ARM tree. - Move the documentation over to driver-api to conform with the rest of the kernel documentation build. - Continue to make the GPIO drivers include only and not the too broad that we want to get rid of. - Managed to remove VLA allocation from two drivers pending more fixes in this area for the next merge window. - Misc janitorial fixes" * tag 'gpio-v4.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (77 commits) gpio: Add Spreadtrum PMIC EIC driver support gpio: Add Spreadtrum EIC driver support dt-bindings: gpio: Add Spreadtrum EIC controller documentation gpio: ath79: Fix potential NULL dereference in ath79_gpio_probe() pinctrl: qcom: Don't allow protected pins to be requested gpiolib: Support 'gpio-reserved-ranges' property gpiolib: Change bitmap allocation to kmalloc_array gpiolib: Extract mask allocation into subroutine dt-bindings: gpio: Add a gpio-reserved-ranges property gpio: mockup: fix a potential crash when creating debugfs entries gpio: pca953x: add compatibility for pcal6524 and pcal9555a gpio: dwapb: Add support for a bus clock gpio: Remove VLA from xra1403 driver gpio: Remove VLA from MAX3191X driver gpio: ws16c48: Implement get_multiple callback gpio: gpio-mm: Implement get_multiple callback gpio: 104-idi-48: Implement get_multiple callback gpio: 104-dio-48e: Implement get_multiple callback gpio: pcie-idio-24: Implement get_multiple/set_multiple callbacks gpio: pci-idio-16: Implement get_multiple callback ...

gpio: Add Spreadtrum PMIC EIC driver support

2018-03-27T13:51:22+00:00

The Spreadtrum PMIC EIC controller contains only one bank of debounce EIC, and this bank contains 16 EICs. Each EIC can only be used as input mode, as well as supporting the debounce and the capability to trigger interrupts when detecting input signals.

gpio: Add Spreadtrum EIC driver support

2018-03-27T13:51:17+00:00

The Spreadtrum digital-chip EIC controller has 4 sub-modules: debounce EIC, latch EIC, async EIC and sync EIC, and each sub-module can has multiple banks and each bank contains 8 EICs. Each EIC can only be used as input mode, and has the capability to trigger interrupts when detecting input signals.

Now that arch/metag/ has been removed, along with TZ1090 SoC support, remove the TZ1090 GPIO drivers. They are of no value without the architecture and SoC platform code. Signed-off-by: James Hogan Cc: linux-gpio@vger.kernel.org Cc: linux-metag@vger.kernel.org Signed-off-by: Linus Walleij

gpio: Add GPIO driver for Nintendo Wii

2018-02-22T12:54:35+00:00

The Nintendo Wii's chipset (called "Hollywood") has a GPIO controller that supports a configurable number of pins (up to 32), interrupts, and some special mechanisms to share the controller between the system's security processor (an ARM926) and the PowerPC CPU. Pin multiplexing is not supported. This patch adds a basic driver for this GPIO controller. Interrupt support will come in a later patch. This patch is based on code developed by Albert Herranz and the GameCube Linux Team, file arch/powerpc/platforms/embedded6xx/hlwd-gpio.c, available at https://github.com/DeltaResero/GC-Wii-Linux-Kernels, but has grown quite dissimilar. v3: - Do some style cleanups, as suggest by Andy Shevchenko v2: - Change hlwd_gpio_driver.driver.name to "gpio-hlwd" to match the filename (was "hlwd_gpio") - Remove unnecessary include of linux/of_gpio.h, as suggested by Linus Walleij. - Add struct device pointer to context struct to make it possible to use dev_info(hlwd->dev, "..."), as suggested by Linus Walleij - Use the GPIO_GENERIC library to reduce code size, as suggested by Linus Walleij - Use iowrite32be instead of __raw_writel for big-endian MMIO access, as suggested by Linus Walleij - Remove commit message paragraph suggesting to diff against the original driver, because it's so different now Signed-off-by: Jonathan Neuschäfer Cc: Albert Herranz Reviewed-by: Segher Boessenkool Reviewed-by: Andy Shevchenko Signed-off-by: Linus Walleij

gpio: raspberrypi-exp: Driver for RPi3 GPIO expander via mailbox service

Pi3 and Compute Module 3 have a GPIO expander that the VPU communicates with. There is a mailbox service that now allows control of this expander, so add a kernel driver that can make use of it.

gpio: Add GPIO support for the ACCES PCIe-IDIO-24 family

2018-01-10T13:39:28+00:00

The ACCES PCIe-IDIO-24 device provides 56 lines of digital I/O (24 lines of optically-isolated non-polarized digital inputs for AC and DC control signals, 24 lines of isolated solid state FET digital outputs, and 8 non-isolated TTL/CMOS compatible programmable I/O). An interrupt is generated when any of the inputs change state (low to high or high to low). Input filter control is not supported by this driver, and input filters are deactivated by this driver. These devices are capable of get_multiple and set_multiple functionality, but these functions have not yet been implemented for this driver. Change-Of-State (COS) detection functionality may be configured to fire interrupts on exclusively rising/falling edges, but this driver currently only implements COS detection for either both edges or none.

gpio: winbond: Add driver

2018-01-09T13:51:00+00:00

This commit adds GPIO driver for Winbond Super I/Os. Currently, only W83627UHG model (also known as Nuvoton NCT6627UD) is supported but in the future a support for other Winbond models, too, can be added to the driver. A module parameter "gpios" sets a bitmask of GPIO ports to enable (bit 0 is GPIO1, bit 1 is GPIO2, etc.). One should be careful which ports one tinkers with since some might be managed by the firmware (for functions like powering on and off, sleeping, BIOS recovery, etc.) and some of GPIO port pins are physically shared with other devices included in the Super I/O chip.
