Restyle all Kconfigs for the rest of "drivers": Menu entries : no space left Menu attributes: 1 TAB Help text : 1 TAB + 2 spaces Replace '---help---' by 'help' Signed-off-by: Johan Jonker [trini: Add missing indentation on a few more multi-paragraph help texts] Signed-off-by: Tom Rini

gpio: Correct dependencies for MCP230xx

2026-05-14T21:54:17Z

This driver depends on DM_I2C and DM_SPI, add it. Fixes: 3b639f643889 ("gpio: mcp230xx: Add support for models with SPI interface.") Signed-off-by: Charles Perry Reviewed-by: Quentin Schulz

gpio: scmi: Add gpio_scmi driver

2026-04-09T02:14:39Z

This provides GPIO support over SCMI. It is built on top of the pinctrl-scmi driver. A typical device tree entry might look like this: gpio1 { compatible = "scmi-pinctrl-gpio"; gpio-controller; #gpio-cells = <2>; ngpios = <10>; gpio-ranges = <&scmi_pinctrl 0 8 4>, <&scmi_pinctrl 4 12 1>, <&scmi_pinctrl 5 15 1>, <&scmi_pinctrl 6 17 4>; pinctrl-names = "default"; pinctrl-0 = <&i2c2_pins>; }; In this GPIO driver the one thing which is different is that in the gpio-ranges the first numbers which represent how the pins are exposed to the users have to start at zero and it can't have gaps.

gpio: Correct dependencies for legacy CMD_PCA953X

2026-04-03T19:42:50Z

The legacy CMD_PCA953X command can only be built when the matching legacy driver is enabled, add that dependency to Kconfig. Signed-off-by: Tom Rini

gpio: Add GPIO delay driver

2026-02-13T07:16:25Z

Add a GPIO controller driver that provides configurable delays when setting GPIO output values. This is useful for hardware that requires specific timing delays during power sequencing or GPIO state changes. The driver wraps underlying GPIO controllers and adds programmable ramp-up and ramp-down delays specified in microseconds through the device tree. Each GPIO can have independent delay timings. Device tree binding matches Linux. Signed-off-by: Michal Simek Link: https://lore.kernel.org/r/575998efc6ba0e405640789cf8d05f0b633f496e.1770105146.git.michal.simek@amd.com

dm: core: Default to using DEVRES outside of xPL

2026-01-09T15:08:14Z

The devm alloc functions that we have may follow the Linux kernel model where allocations are (almost always) automatically free()'d. However, quite often we don't enable, in full U-Boot, the tracking and free()'ing functionality. This in turn leads to memory leaks because the driver author expects that since the functions have the same name as in the Linux Kernel they have the same behavior. In turn we then get functionally correct commits such as commit 00e1fed93c8c ("firmware: ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually add these calls. Rather than manually tracking allocations and implementing free()s, rework things so that we follow expectations by enabling the DEVRES functionality (outside of xPL phases). This turns DEVRES from a prompted symbol to a symbol that must be select'd, and we now remove our non-managed alloc/free functions from outside of xPL builds.
