GPIO:Starfive-jh7110: Add GPIO driver for JH7110

2022-10-18T08:24:33+00:00

Support for GPIO controller on starfive JH7110 SoCs. Signed-off-by: yanhong.wang

pci: Drop DM_PCI

2021-09-13T22:23:13+00:00

This option has not effect now. Drop it, using PCI instead where needed. Signed-off-by: Simon Glass

gpio: mcp230xx: Introduce new driver

2021-08-22T08:53:14+00:00

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

global: Convert simple_strtoul() with decimal to dectoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 10 in each call. Add a new dectoul() function and update the code to use it. Signed-off-by: Simon Glass

global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 16 in each call. Add a new hextoul() function and update the code to use it. Add a proper comment to simple_strtoul() while we are here. Signed-off-by: Simon Glass

Rename GPIO_SUPPORT to GPIO

Rename these options so that CONFIG_IS_ENABLED can be used with them. Signed-off-by: Simon Glass

i2c: pcf8575: Add support for 8 bit I2C IO expanders (like pca8574)

2021-07-23T11:13:25+00:00

This patch add support for using NXP's pca8574 I2C IO expander, which has only 8 IO lines. After this change the .data member's information from struct udevice_id are used to either sent one or two bytes. Moreover, the '_le16' suffix from pcf8575_i2c_{write|read}_le16() functions have been removed as now we also sent 8 bit data. Signed-off-by: Lukasz Majewski Reviewed-by: Heiko Schocher

i2c: pcf8575: Remove not used members of pcf8575_chip structure

2021-07-23T11:13:25+00:00

Those members are not used anymore as ones from gpio_dev_priv structure (when DM_GPIO support is enabled) are used instead. Signed-off-by: Lukasz Majewski Reviewed-by: Heiko Schocher

gpio: Add driver for Nomadik GPIO

2021-07-14T20:47:56+00:00

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
