gpio: fxl6408: add I2C GPIO expander driver

2023-03-15T12:49:18+00:00

Add minimal driver for Fairchild FXL6408 8-bit I2C-controlled GPIO expander using the generic regmap based GPIO driver (GPIO_REGMAP). The driver implements setting the GPIO direction, reading inputs and writing outputs. In addition to that the FXL6408 has the following functionalities: - allows to monitor input ports for data transitions with an interrupt pin - all inputs can be configured with pull-up or pull-down resistors Datasheet: https://www.onsemi.com/download/data-sheet/pdf/fxl6408-d.pdf Signed-off-by: Emanuele Ghidoli Co-developed-by: Francesco Dolcini Signed-off-by: Francesco Dolcini Reviewed-by: Andy Shevchenko [Bartosz: order includes alphabetically] Signed-off-by: Bartosz Golaszewski

gpio: loongson: add gpio driver support

2023-03-06T09:44:28+00:00

The Loongson platforms GPIO controller contains 60 GPIO pins in total, 4 of which are dedicated GPIO pins, and the remaining 56 are reused with other functions. Each GPIO can set input/output and has the interrupt capability. This driver added support for Loongson GPIO controller and support to use DTS or ACPI to descibe GPIO device resources.

mfd: remove ucb1400 support

2023-02-01T16:23:38+00:00

The ucb1400 MFD driver and its gpio and touchscreen child drivers were only used on a few PXA machines that were unused for a while and are now removed. Removing these leaves the AC97 support as ALSA specific, no other drivers are now connected through this interface.

gpiolib: add support for software nodes

2022-11-15T10:21:43+00:00

Now that static device properties understand notion of child nodes and references, let's teach gpiolib to handle them: - GPIOs are represented as a references to software nodes representing gpiochip - references must have 2 arguments - GPIO number within the chip and GPIO flags (GPIO_ACTIVE_LOW/GPIO_ACTIVE_HIGH, etc) - a new PROPERTY_ENTRY_GPIO() macro is supplied to ensure the above - name of the software node representing gpiochip must match label of the gpiochip, as we use it to locate gpiochip structure at runtime The following illustrates use of software nodes to describe a "System" button that is currently specified via use of gpio_keys_platform_data in arch/mips/alchemy/board-mtx1.c. It follows bindings specified in Documentation/devicetree/bindings/input/gpio-keys.yaml. static const struct software_node mxt1_gpiochip2_node = { .name = "alchemy-gpio2", }; static const struct property_entry mtx1_gpio_button_props[] = { PROPERTY_ENTRY_U32("linux,code", BTN_0), PROPERTY_ENTRY_STRING("label", "System button"), PROPERTY_ENTRY_GPIO("gpios", &mxt1_gpiochip2_node, 7, GPIO_ACTIVE_LOW), { } }; Similarly, arch/arm/mach-tegra/board-paz00.c can be converted to: static const struct software_node tegra_gpiochip_node = { .name = "tegra-gpio", }; static struct property_entry wifi_rfkill_prop[] __initdata = { PROPERTY_ENTRY_STRING("name", "wifi_rfkill"), PROPERTY_ENTRY_STRING("type", "wlan"), PROPERTY_ENTRY_GPIO("reset-gpios", &tegra_gpiochip_node, 25, GPIO_ACTIVE_HIGH); PROPERTY_ENTRY_GPIO("shutdown-gpios", &tegra_gpiochip_node, 85, GPIO_ACTIVE_HIGH); { }, }; static struct platform_device wifi_rfkill_device = { .name = "rfkill_gpio", .id = -1, }; ... software_node_register(&tegra_gpiochip_node); device_create_managed_software_node(&wifi_rfkill_device.dev, wifi_rfkill_prop, NULL); Acked-by: Linus Walleij Reviewed-by: Andy Shevchenko Signed-off-by: Dmitry Torokhov Signed-off-by: Bartosz Golaszewski
