One notable feature of Ivy is the analog inputs. These inputs are multiplexed, allowing the same input to measure either voltage or current. For current measurements, a GPIO switch enables or disables the shunt resistor. This process is automatically managed by the Linux kernel using the IIO and MUX subsystems. Voltage measurement is always enabled, but the voltage measured by the ADC is scaled by a cascade voltage divider. In the device tree, the equivalent gain of the voltage divider is used, which can be calculated as follows: ------------ + | .-. R1=30K | | | | '-' |------------------- Analog Input (AIN) | | .-. .-. R2=10K | | R3=30K | | | | | | '-' '-' | | | |-------- | .-. + | R4=10K | | | | | ADC Input (Channels 0 and 1) | '-' - | | - -----------| |-------- === === GND GND Vin = Analog Input (AIN) Vout = ADC Input Rth = Thevenin Equiv. Resistance Vth = Thevenin Equiv. Voltage RL = Load Resistor R1 = 30K, R2 = 10K, R3 = 30K, R4 = 10K RL = R4 = 10K Rth = (R1 // R2) + R3 = 37500 Ohms Vth = (Vin * R2) / (R1 + R2) = Vin/4; Vout = (Vth * RL)/ (Rth + RL) = Vth/4.75 = Vin/19 Gain = Vout/Vin = 1/19 https://www.toradex.com/products/carrier-board/ivy-carrier-board Signed-off-by: João Paulo Gonçalves Signed-off-by: Francesco Dolcini --- arch/arm64/boot/dts/freescale/Makefile | 2 + .../boot/dts/freescale/imx8mp-verdin-ivy.dtsi | 512 ++++++++++++++++++ .../freescale/imx8mp-verdin-nonwifi-ivy.dts | 18 + .../dts/freescale/imx8mp-verdin-wifi-ivy.dts | 18 + 4 files changed, 550 insertions(+) create mode 100644 arch/arm64/boot/dts/freescale/imx8mp-verdin-ivy.dtsi create mode 100644 arch/arm64/boot/dts/freescale/imx8mp-verdin-nonwifi-ivy.dts create mode 100644 arch/arm64/boot/dts/freescale/imx8mp-verdin-wifi-ivy.dts diff --git a/arch/arm64/boot/dts/freescale/Makefile b/arch/arm64/boot/dts/freescale/Makefile index 9d3df8b218a2..349ff1af0361 100644 --- a/arch/arm64/boot/dts/freescale/Makefile +++ b/arch/arm64/boot/dts/freescale/Makefile @@ -189,10 +189,12 @@ dtb-$(CONFIG_ARCH_MXC) += imx8mp-venice-gw74xx.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-venice-gw75xx-2x.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-nonwifi-dahlia.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-nonwifi-dev.dtb +dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-nonwifi-ivy.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-nonwifi-mallow.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-nonwifi-yavia.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-wifi-dahlia.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-wifi-dev.dtb +dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-wifi-ivy.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-wifi-mallow.dtb dtb-$(CONFIG_ARCH_MXC) += imx8mp-verdin-wifi-yavia.dtb diff --git a/arch/arm64/boot/dts/freescale/imx8mp-verdin-ivy.dtsi b/arch/arm64/boot/dts/freescale/imx8mp-verdin-ivy.dtsi new file mode 100644 index 000000000000..db1b4ee7728c --- /dev/null +++ b/arch/arm64/boot/dts/freescale/imx8mp-verdin-ivy.dtsi @@ -0,0 +1,512 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT +/* + * Copyright 2024 Toradex + * + * Common dtsi for Verdin IMX8MP SoM on Ivy carrier board + * + * https://www.toradex.com/computer-on-modules/verdin-arm-family/nxp-imx-8m-plus + * https://www.toradex.com/products/carrier-board/ivy-carrier-board + */ + +#include +#include +#include + +/ { + /* AIN1 Voltage w/o AIN1_MODE gpio control */ + ain1_voltage_unmanaged: voltage-divider-ain1 { + compatible = "voltage-divider";
