gpio: add sl28cpld driver

2022-02-28T06:29:35Z

The gpio block is part of the sl28cpld sl28cpld management controller. There are three different flavors: the usual input and output where the direction is configurable, but also input only and output only variants. Signed-off-by: Michael Walle [Rebased] Signed-off-by: Priyanka Jain

GPIO: fxl6408: Add support for FXL6408 GPIO expander

2022-02-05T12:38:39Z

Initial support for Fairchild's 8 bit I2C gpio expander FXL6408. The CONFIG_FXL6408_GPIO define enables support for such devices.

zynqmp: gpio: Add support for zynqmp gpio modepin driver

2022-01-05T09:22:02Z

ZynqMP modepin driver has capability to get/set/check status of modepin gpios. These modepins are accessed using xilinx firmware. In modepin register, [3:0] bits set direction, [7:4] bits read IO, [11:8] bits set/clear IO.

drivers/gpio: add support for MAX7320 i2c i/o expander

This commit adds support for the MAX7320 (and clones) gpio expander. Signed-off-by: Hannes Schmelzer

arm: Remove aspenite board

2021-10-01T16:10:09Z

This board has not been converted to CONFIG_DM by the deadline. Remove it. As this is the last armada100 platform, remove that support as well. Cc: Prafulla Wadaskar Signed-off-by: Tom Rini

dm: gpio: Add of-platdata support

2021-09-25T15:46:15Z

Add support for accessing GPIOs using of-plata. This uses the same mechanism as for clocks, but allows use of the xlate() method so that the driver can interpret the parameters. Update the condition for GPIO_HOG so that it is not built into SPL, since it needs SPL_OF_REAL which is not enabled in sandbox_spl. Signed-off-by: Simon Glass

gpio: mcp230xx: Introduce new driver

2021-08-22T08:53:14Z

Introduce driver for I2C based MCP230xx GPIO chips, which are quite common and already well supported by the Linux kernel. Reviewed-by: Simon Glass Signed-off-by: Sebastian Reichel Reviewed-by: Simon Glass

gpio: Add driver for Nomadik GPIO

2021-07-14T20:47:56Z

Nomadik GPIO is a fairly simple GPIO module used in the ST-Ericsson Ux500 SoCs (and some older Nomadik SoCs). It uses registers where each GPIO is represented as a single bit, plus "set" and "clear" registers that allow updating the state without having to read the existing state. The driver implements support for it for use together with DM_GPIO and the existing ste-dbx5x0.dtsi device tree. Cc: Linus Walleij Signed-off-by: Stephan Gerhold Reviewed-by: Linus Walleij

gpio: Drop long unused DB8500 GPIO driver

2021-07-14T20:47:55Z

The original U-Boot port for the ST-Ericsson U8500 SoC was dropped in commit 68282f55b846 ("arm: Remove unused ST-Ericsson u8500 arch"). Most of the drivers related to the old port were removed, but the db8500_gpio.c driver was forgotten for some reason. There is no way to select it and it does not compile anymore because of missing headers, so let's just remove it. The new port for U8500 introduced in commit 689088f9dae8 ("arm: Add support for ST-Ericsson U8500 SoC") fully embraces the new Driver Model and device trees where possible, so this is preparation to add a new, simplified GPIO driver based on DM_GPIO.

arm: Remove spear600 boards and the rest of SPEAr support

2021-07-08T02:22:42Z

These boards have not been converted to CONFIG_DM_USB by the deadline and is also missing conversion to CONFIG_DM. Remove them. As this is the last of the SPEAr platforms, so remove the rest of the remaining support as well. Cc: Vipin Kumar Signed-off-by: Tom Rini
