Hi,
i just tested the diff that does print pinmuxes during boot, and unfortunately
it does seem as if something somewhere does reset the mux of leds from output
back to input in between toggling the led in u-boot & printing the mux in
sxipio_attach_gpio()..
=> gpio set ph20
gpio: pin ph20 (gpio 244) value is 1
=> gpio set ph21
gpio: pin ph21 (gpio 245) value is 1
=> run bootcmd
switch to partitions #0, OK
mmc0 is current device

Found EFI removable media binary efi/boot/bootarm.efi
reading efi/boot/bootarm.efi
...
...
H21 mux 0<gpio_in>- adding
H22 mux 0<gpio_in>- adding
...
now those got added so that i can seemingly toggle w/o errors, once set back
to output, ymmv. different SoC and all..
Hit any key to stop autoboot: 0
=> gpio toggle ph21
gpio: pin ph21 (gpio 245) value is 1
=> run bootcmd

Welcome to OpenBSD: The proactively secure Unix-like operating system.
Please use the sendbug(1) utility to report bugs in the system.
Before reporting a bug, please try to reproduce it with the latest
version of the code. With bug reports, please try to ensure that
enough information to reproduce the problem is enclosed, and if a
known fix for it exists, include that as well.
You have mail.

>
> SYNOPSIS
> gpioctl [-q] device pin [0 | 1 | 2 | on | off | toggle]
> gpioctl [-q] device pin set [flags] [name]
> gpioctl [-q] device pin unset
> gpioctl [-q] device attach device offset mask [flag]
> gpioctl [-q] device detach device
>
> DESCRIPTION
> The gpioctl program allows manipulation of GPIO (General Purpose
> Input/Output) device pins. Such devices can be either part of the
> chipset or embedded CPU, or a separate chip. The usual way of using GPIO
> is to connect some simple devices such as LEDs and 1-wire thermal sensors
> to its pins.
>
> Each GPIO device has an associated device file in the /dev directory.
> device can be specified with or without the /dev prefix. For example,
> /dev/gpio0 or gpio0.
>
> GPIO pins can be either "read" or "written" with the values of logical 0
> or 1. If only a pin number is specified on the command line, the pin
> state will be read from the GPIO controller and displayed. To write to a
> pin, a value must be specified after the pin number. Values can be
> either 0 or 1. A value of 2 has a special meaning: it "toggles" the pin,
> i.e. changes its state to the opposite. Instead of the numerical values,
> the word on, off, or toggle can be used.
>
> Only pins that have been configured at securelevel 0, typically during
> system startup, are accessible once the securelevel has been raised.
> Pins can be given symbolic names for easier use. Besides using
> individual pins, device drivers that use GPIO pins can be attached to a
> gpio(4) device using the gpioctl command.
>
> The following configuration flags are supported by the GPIO framework.
> Note that not all the flags can be supported by the particular GPIO
> controller.
>
> in input direction
> out output direction
> inout bi-directional
> od open-drain output
> pp push-pull output
> tri tri-state (output disabled)
> pu internal pull-up enabled
> pd internal pull-down enabled
> iin invert input
> iout invert output
>
> When attaching an I2C device, if the flag argument is set to 0x01, the
> order of the SDA and SCL signals is reversed (see gpioiic(4)).
>
> When executed with only the gpio(4) device name as argument, gpioctl
> reads information about the GPIO device and displays it. At securelevel
> 0 the number of physically available pins is displayed, at higher
> securelevels the number of configured (set) pins is displayed.
>
> The options are as follows:
>
> -q Operate quietly i.e. nothing is printed to stdout.
>
> FILES
> /dev/gpiou GPIO device unit u file.
>
> EXAMPLES
> Configure pin 20 to have push-pull output:
>
> # gpioctl gpio0 20 set out pp
>
> Write logical 1 to pin 20:
>
> # gpioctl gpio0 20 1
>
> Attach a onewire(4) bus on a gpioow(4) device on pin 4:
>
> # gpioctl gpio0 attach gpioow 4 0x01
>
> Detach the gpioow0 device:
>
> # gpioctl gpio0 detach gpioow0
>
> Configure pin 5 as output and name it error_led:
>
> # gpioctl gpio0 5 set out error_led
>
> Toggle the error_led:
>
> # gpioctl gpio0 error_led 2
