gpio: Move OMAP_GPIO to Kconfig

2017-05-15T14:40:00Z

This driver is used often enough such that we want to have this enabled by default on any ARCH_OMAP2PLUS board, and this only compiles on ARCH_OMAP2PLUS due to required defines, so mark that as the depends. Signed-off-by: Tom Rini

dm: gpio: add BCM6345 gpio driver

2017-05-10T14:16:09Z

This driver is based on linux/arch/mips/bcm63xx/gpio.c, simplified to allow defining one or two independent banks for each Broadcom SoC. Signed-off-by: Álvaro Fernández Rojas Reviewed-by: Simon Glass

gpio: Add Rapid GPIO2P driver for i.MX7ULP

2017-03-17T08:27:08Z

Add the imx_rgpio2p driver for Rapid GPIO2P controllers on i.MX7ULP. Have added all ports on RGPIO2P_0 and RGPIO2P_1. The configurations CONFIG_IMX_RGPIO2P and CONFIG_DM_GPIO must be set to y to enable the drivers. To use the GPIO function, the IBE and OBE needs to set in IOMUXC. We did not set the bits in driver, but leave them to IOMUXC settings of the GPIO pins. User should use IMX_GPIO_NR to generate the GPIO number for gpio APIs access.

Rework the driver to support driver model and device tree, and support to regard the pio4 pinctrl device as a child of atmel_pio4 device. Signed-off-by: Wenyou Yang Reviewed-by: Simon Glass

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.

dm: gpio: Add driver for MPC85XX GPIO controller

2016-06-04T05:13:24Z

This patch adds a driver for the built-in GPIO controller of the MPC85XX SoC (probably supporting other PowerQUICC III SoCs as well). Each GPIO bank is identified by its own entry in the device tree, i.e. gpio-controller@fc00 { #gpio-cells = <2>; compatible = "fsl,pq3-gpio"; reg = <0xfc00 0x100> } By default, each bank is assumed to have 32 GPIOs, but the ngpios setting is honored, so the number of GPIOs for each bank in configurable to match the actual GPIO count of the SoC (e.g. the 32/32/23 banks of the P1022 SoC). The usual functions of GPIO drivers (setting input/output mode and output value setting) are supported. The driver has been tested on MPC85XX, but it is likely that other PowerQUICC III devices will work as well. Signed-off-by: Mario Six Reviewed-by: Simon Glass Reviewed-by: York Sun
