gpio: ds4520: Add ADI DS4520 GPIO Expander Support

2023-07-29T13:56:33+00:00

The DS4520 is a 9-bit nonvolatile (NV) I/O expander. It offers users a digitally programmable alternative to hardware jumpers and mechanical switches that are being used to control digital logic node. Signed-off-by: Okan Sahin Signed-off-by: Bartosz Golaszewski

gpio: mlxbf3: Add gpio driver support

2023-06-16T09:08:32+00:00

Add support for the BlueField-3 SoC GPIO driver. This driver configures and handles GPIO interrupts. It also enables a user to manipulate certain GPIO pins via libgpiod tools or other kernel drivers. The usables pins are defined via the "gpio-reserved-ranges" property. Signed-off-by: Asmaa Mnebhi Reviewed-by: Andy Shevchenko Reviewed-by: Linus Walleij Signed-off-by: Bartosz Golaszewski

gpio: delay: Remove duplicative functionality

2023-06-16T09:02:11+00:00

Now that GPIO aggregator supports a delay line, drop the duplicative functionality, i.e. the entire gpio-delay driver. Reviewed-by: Geert Uytterhoeven Reviewed-by: Linus Walleij Signed-off-by: Andy Shevchenko Tested-by: Alexander Stein Signed-off-by: Bartosz Golaszewski

gpio: tps65219: add GPIO support for TPS65219 PMIC

2023-06-13T12:49:56+00:00

Add support for TPS65219 PMICs GPIO interface. 3 GPIO pins: - GPIO0 only is IO but input mode reserved for MULTI_DEVICE_ENABLE usage. - GPIO1 and GPIO2 are Output only and referred as GPO1 and GPO2 in spec. GPIO0 is statically configured as input or output prior to Linux boot. it is used for MULTI_DEVICE_ENABLE function. This setting is statically configured by NVM. GPIO0 can't be used as a generic GPIO (specification Table 8-34). It's either a GPO when MULTI_DEVICE_EN=0 or a GPI when MULTI_DEVICE_EN=1. Datasheet describes specific usage for non standard GPIO.

gpio: Add gpio delay driver

2023-06-02T16:29:15+00:00

This driver implements a GPIO enable/disable delay. It supports a list of GPIO outputs, which ramp-up/ramp-down delay can be specified at consumer location. The main purpose is to address external, passive delays upon line voltage changes. Signed-off-by: Alexander Stein Acked-by: Linus Walleij Signed-off-by: Bartosz Golaszewski
