[PATCH v3 0/4] ARM: dts: vf: Iris carrier board for the Colibri VF50 and VF61

[PATCH v3 0/4] ARM: dts: vf: Iris carrier board for the Colibri VF50 and VF61

[Mehmet Fide]

From: Mehmet Fide <mehmet.fide@screeningeagle.com>

This adds a device tree for the Toradex Iris carrier board carrying the
Vybrid Colibri modules, plus two small preparatory patches for the
module-level dtsi that the i.MX Colibri variants already had.

Everything was tested on a Colibri VF50 on an Iris V1.1 running 6.18:
Ethernet, USB host and OTG, all three UARTs, i2c with the carrier RTC,
SPI, the microSD slot and the RS232 transceiver hogs.

Changes in v3, following Krzysztof's review:
- fold the Iris compatibles into the existing -on-eval enum entries
  instead of adding standalone entries
- use hyphens in the newly introduced compatibles
  (toradex,vf500-colibri-vf50-on-iris, toradex,vf610-colibri-vf61-on-iris)
- drop the fixed 5V regulator that only fed the VBUS regulator
- sent as a fresh thread instead of in reply to v2

Changes in v2:
- add the dt-bindings patch for the new compatibles
- describe the USB host VBUS regulator instead of hogging USBH_PEN

[PATCH v3 1/4] ARM: dts: vf-colibri: apply the EXT_IO pin group

[Mehmet Fide]

From: Mehmet Fide <mehmet.fide@screeningeagle.com>

pinctrl_gpio_ext describes the three Colibri EXT_IO pins, but no node
references it, so the pin controller never applies it and the pads keep
whatever mux and bias they came up with. It is the only pin group in the
Vybrid Colibri device trees that is defined and never used.

The three pins are GPIOs on gpio2 and belong to no device, so hog the
group on that controller. Referencing it from &iomuxc would work too, but
the pin controller would then depend on one of its own children, which
fw_devlink reports as a dependency cycle.

[PATCH v3 2/4] ARM: dts: vf-colibri: name the SODIMM gpio lines

[Mehmet Fide]

From: Mehmet Fide <mehmet.fide@screeningeagle.com>

The Colibri modules expose most of their GPIOs on numbered SODIMM pins,
and the i.MX ones already carry those numbers as gpio-line-names, so the
gpiod tools print SODIMM_43 rather than a bank and an offset. Do the same
for the Vybrid modules.

The 99 names come from the pinout table of the Colibri VFxx datasheet
(Toradex 101355). Verified on a Colibri VF50, where gpioinfo now names
every pin the datasheet lists.

From: Mehmet Fide <mehmet.fide@screeningeagle.com>

The Iris is a small off-the-shelf carrier board for the Colibri
family. Extend the evaluation board entries with the compatibles for
a Colibri VF50 or VF61 sitting on it.

[PATCH v3 4/4] ARM: dts: vf: add Iris carrier board support for Colibri VF50 and VF61

[Mehmet Fide]

From: Mehmet Fide <mehmet.fide@screeningeagle.com>

The Iris is a small off-the-shelf carrier board for the Colibri
family. Describe what the board itself provides: Ethernet, one USB
host and one OTG port, the pin header UARTs, i2c with the carrier
RTC on it, PWM, SPI and the microSD slot. The host port gets its
VBUS through a regulator on SODIMM 129, and the two GPIOs that turn
the RS232 transceivers on, SODIMM 102 and 104, are hogged. The
touchscreen is an add-on rather than part of the board, so it is
left out.

This describes an Iris V1.1. A V2.0 carries the same signals on the
same pins; what it adds, and what this does not describe, is the
regulator on SODIMM 100 that can cut power to the uSD slot.

Tested on a Colibri VF50 on an Iris V1.1 running 6.18: Ethernet at
100Mbps/Full, a USB dongle enumerating once the VBUS regulator is in
place, the RTC read back over i2c0, all three UARTs, the SPI
controller registering, the microSD slot, and both hogs holding
their pins.
