[PATCH v1 0/3] arm64: dts: ti: k3-am62-verdin: Add Ivy carrier board

[Francesco Dolcini]

From: Francesco Dolcini <francesco.dolcini@toradex.com>

Add support for the Toradex Verdin AM62 Ivy carrier board. Ivy is a carrier
board designed for industrial environments, supporting industrial
I/O interfaces such as CAN, RS485, RS232, Gigabit Ethernet, 0-25mA analog
inputs, relays, PCIe and more. The board also includes a TPM for security
applications.

[PATCH v1 3/3] arm64: dts: ti: k3-am62-verdin: Add Ivy carrier board

[Francesco Dolcini]

From: João Paulo Gonçalves <joao.goncalves@toradex.com>

Add Toradex Verdin Ivy carrier board support. 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

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y ti/k3-am625-verdin-nonwifi-ivy.dtb ti/k3-am625-verdin-wifi-ivy.dtb' for 20240924120044.130913-1-francesco@dolcini.it:

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/3] dt-bindings: arm: ti: Add verdin am62 ivy board

      commit: 25c8a5bebd652ad26d99701c9b2e979d7a1c11b4
[3/3] arm64: dts: ti: k3-am62-verdin: Add Ivy carrier board
      commit: 881f5e9d808243d27830b3ed294e2e8abda05e62

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
