New device-tree properties have been added. Note that this patch requires the following commit (still pending): https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20220404215754.30126-2-macroalpha82@gmail.com/ - rockchip,resistor-sense-micro-ohms: The value in microohms of the sample resistor. - rockchip,sleep-enter-current-microamp: The value in microamps of the sleep enter current. - rockchip,sleep-filter-current: The value in microamps of the sleep filter current.
