dm: treewide: Do not use the return value of simple uclass iterator

2022-10-29T13:36:33+00:00

uclass_first_device/uclass_next_device return value will be removed,
don't use it.

With the current implementation dev is equivalent to !ret. It is
redundant to check both, ret check can be replaced with dev check, and
ret check inside the iteration is dead code.

gpio-uclass: fix gpio lookup by label

2022-10-29T13:36:33+00:00

Matching anything that just happens to have the sought-for label as a
prefix is wrong. For example, if the board designer has designated 10
lines for debug purposes, named "debug1" through "debug10", and we are
looking up "debug1", if debug10 happens to be met first during the
iteration we'd wrongly return that.

In theory, this can break existing users that could rely on this
quirk, but OTOH keeping the current broken semantics can cause a lot
of grief for people hitting this in the future and not understanding
why they don't find the line they expect. Considering how few in-tree
defconfigs currently set DM_GPIO_LOOKUP_LABEL (ignoring sandbox, only
four "real" boards), let's fix it before the use becomes more
widespread.

gpio: turris_omnia_mcu: Fix registering gpios

2022-09-26T08:04:37+00:00

Currently all GPIOs supported by CMD_EXT_CONTROL/CMD_GET_EXT_CONTROL_STATUS
commands (last 16 GPIOs) are available only when FEAT_PERIPH_MCU feature
bit is set. So do not register these GPIOs by U-Boot driver when this
feature bit is not set, so U-Boot 'gpio' command would see only GPIOs which
really exists.
