I was setting gpioV4-7 to "1110" using the QOM pin property handler and
noticed that lowering gpioV7 was inadvertently lowering gpioV4-6 too.
(qemu) qom-set /machine/soc/gpio gpioV4 true
(qemu) qom-set /machine/soc/gpio gpioV5 true
(qemu) qom-set /machine/soc/gpio gpioV6 true
(qemu) qom-get /machine/soc/gpio gpioV4
true
(qemu) qom-set /machine/soc/gpio gpioV7 false
(qemu) qom-get /machine/soc/gpio gpioV4
false
An expression in aspeed_gpio_set_pin_level was using a logical NOT
operator instead of a bitwise NOT operator:
value &= !pin_mask;
The original author probably intended to make a bitwise NOT expression
"~", but mistakenly used a logical NOT operator "!" instead. Some
programming languages like Rust use "!" for both purposes.

AST2500")
