The public datasheets of the following Amlogic SoCs describe a typical resistor value for the built-in pull up/down resistor: - Meson8/8b/8m2: not documented - GXBB (S905): 60 kOhm - GXL (S905X): 60 kOhm - GXM (S912): 60 kOhm - G12B (S922X): 60 kOhm - SM1 (S905D3): 60 kOhm The public G12B and SM1 datasheets additionally state min and max values: - min value: 50 kOhm for both, pull-up and pull-down - max value for the pull-up: 70 kOhm - max value for the pull-down: 130 kOhm Use 60 kOhm in the pinctrl-meson driver as well so it's shown in the debugfs output. It may not be accurate for Meson8/8b/8m2 but in reality 60 kOhm is closer to the actual value than 1 Ohm.
