[PATCH v2 09/10] iio: adc: ad7606: fix standby gpio state to match the documentation

From: Guillaume Stols
Date: Fri Jun 28 2024 - 10:50:25 EST


The binding's documentation specifies that "As the line is active low, it
should be marked GPIO_ACTIVE_LOW". However, in the driver, it was handled
the opposite way. This commit sets the driver's behaviour in sync with the
documentation
