Hi,
I am trying to enable an output and set value low with a gpio-hog on
mt7621 soc.
But it doesn't matter what I try, output-low/output-high and/or
GPIO_ACTIVE_LOW
The gpio is always set as output and set HIGH so gpio output = VCC.
When set the gpio as input, the gpio is configured as an input.
Goal is to set GPIO7 output to GND/low.
In this case the GPIO7 is ACTIVE_LOW.
Used device Ubiquity EdgeRouter X SFP with MediaTek mt7621 MIPS SOC.
Kernel: Linux-5.4.0-rc6-next-20191107
To print this line "gpiochip_add_data_with_key: gpiochip0 gpio7: 0x843"
I used this patch, it prints the desc->flags only for the 7th gpio of that
gpiochip.
diff --git a/drivers/gpio/gpiolib.c b/drivers/gpio/gpiolib.c

}
acpi_gpiochip_add(chip);
Here are the results what I tested.

So as you can see gpio-hog is parsed well by the kernel.
But it setting up the data value is not.
I think is a long time faulty because I tried many months ago and also
hit this
issue but I did not investigated the issue.
If I try this on the openwrt 4.19 kernel is works fine but openwrt has
an other
gpio driver.
I currently using this gpio-leds hack to enable gpio7.
leds {
compatible = "gpio-leds";
/* Fixme: Currently a hack to enable SFP clk gate. */
sfp {
label = "sfp:i2c";
gpios = <&gpio 7 GPIO_ACTIVE_LOW>;
default-state = "off";
linux,default-trigger = "default-on";
};
};
So any ideas what is wrong?
Here the full boot log of case 3 with gpio and pinctrl debug enabled.
