doc: remove u-boot,boot-led and u-boot,error-led from "binding"

2025-12-03T17:03:45Z

We're aiming to reduce the amount of U-Boot-specific and out-of-spec Device Tree additions. Those two properties haven't been doing anything for a long time already, except when read by board files manually. This is still the case for STM32 boards but those will be migrated in the near future according to their maintainer. In any case, let's not encourage people to add either of these properties to new or existing Device Trees and remove it from the bindings. Signed-off-by: Quentin Schulz

env: Rename ENV_MMC_PARTITION to ENV_MMC_SW_PARTITION

2025-06-20T18:15:08Z

Rename the variable and add ENV_ prefix, so that all configuration options which are related to environment would have an CONFIG_ENV_ prefix. No functional change. Use ENV_MMC_SW_PARTITION to clarify this is the SD/MMC software partition table entry selector. Update the help text accordingly. Signed-off-by: Marek Vasut

env: Rename SYS_MMC_ENV_DEV to ENV_MMC_DEVICE_INDEX

2025-06-20T18:15:08Z

Rename the variable and add ENV_ prefix, so that all configuration options which are related to environment would have an CONFIG_ENV_ prefix. No functional change. Use ENV_MMC_DEVICE_INDEX to clarify this is the SD/MMC device index, a number, as enumerated by U-Boot. Update the help text accordingly. Signed-off-by: Marek Vasut

env: mmc: statically set the environment partition name

2023-07-14T19:21:07Z

The new opt-out setting, CONFIG_ENV_MMC_PARTITION, statically sets the MMC environment partition name. Prior to this patch, the only way to declare this partition name was by creating a 'u-boot,mmc-env-partition' parameter in the device-tree's /config node. This setting provides additional flexibility, particularly in cases where accessing the device-tree is not straightforward (e.g. QEMU). If undeclared, the device-tree's setting will be used.

treewide: fdt: Move fdt_get_config_... to ofnode_conf_read...

2021-09-25T15:46:15Z

The current API is outdated as it requires a devicetree pointer. Move these functions to use the ofnode API and update this globally. Add some tests while we are here. Correct the call in exynos_dsim_config_parse_dt() which is obviously wrong. Signed-off-by: Simon Glass

doc: Tidy up the bindings for the config/ node

2021-09-11T09:02:02Z

Sort these and add a type so it is clear how to set the value. Add a note about usage to the top. Correct the 'no-keyboard' binding which is missing a prefix. Signed-off-by: Simon Glass Reviewed-by: Marcel Ziswiler Signed-off-by: Heinrich Schuchardt

rockchip: rk3399-puma: add code to allow forcing a power-on reset

2017-11-30T21:59:54Z

The reset circuitry in the RK3399 only resets 'almost all logic' when a software reset is performed. To make our software maintenance easier in the future, we want to have the option (controlled by a DTS property) to force all reset causes other than a power-on reset to trigger a power-on reset via a GPIO trigger. This adds the necessary support to the rk3399-puma (i.e. RK3399-Q7) board-support and the documentation for the new property (sysreset-gpio) within the /config-node.
