gpio: add gpio-hog support

2019-07-13T15:11:30Z

add gpio-hog support. GPIO hogging is a mechanism providing automatic GPIO request and configuration as part of the gpio-controller's driver probe function. for more infos see: doc/device-tree-bindings/gpio/gpio.txt Signed-off-by: Heiko Schocher Tested-by: Michal Simek (zcu102) Tested-by: Patrick Delaunay

gpio: Add driver for TI PCF8575 I2C GPIO expander

2016-08-08T17:32:53Z

TI's PCF8575 is a 16-bit I2C GPIO expander.The device features a 16-bit quasi-bidirectional I/O ports. Each quasi-bidirectional I/O can be used as an input or output without the use of a data-direction control signal. The I/Os should be high before being used as inputs. Read the device documentation for more details[1]. This driver is based on pcf857x driver available in Linux v4.7 kernel. It supports basic reading and writing of gpio pins.

x86: Update x86-pinctrl driver device-tree-bindings doc

2016-06-12T04:19:35Z

This updates the device-tree-bindings doc for x86-pinctrl driver: - clarify "gpio-offset" is required only when "mode-gpio" is set - correct property name "pull-strength" - use tab instead of space at several places Signed-off-by: Bin Meng Reviewed-by: Stefan Roese Reviewed-by: Simon Glass

gpio: add Tegra186 GPIO driver

2016-05-31T16:54:24Z

Tegra186's GPIO controller register layout is significantly different from previous chips, so add a new driver for it. In fact, there are two different GPIO controllers in Tegra186 that share a similar register layout, but very different port mapping. This driver covers both. The DT binding is already present in the Linux kernel (in linux-next via the Tegra tree so far). Signed-off-by: Stephen Warren Reviewed-by: Simon Glass # v1 Signed-off-by: Tom Warren
