[PATCH v4 0/3] arm64: dts/bindings: Add support for BeagleBadge

[Judith Mendez]

Hi,

BeagleBoard.org BeagleBadge[1] is a compact, affordable open source
hardware [2] single board computer based on the Texas Instruments AM62L3
SoC designed for IoT and embedded applications. Add base support for
the same.

SD boot:
Link: https://gist.github.com/jmenti/8818fa277597de927dd2b42ab1d2552f

This patch series adds:
- Device tree bindings update for am62l3-badge
- Device tree source for BeagleBadge board
- Defconfig: drivers for BeagleBadge

Changelog since v3:
- Fix newline in commit messages
- Drop vendor URLs
DTS:
- Add bootph flags in wakup i2c & PMIC nodes for completeness
- Drop unneeded header files

v3

Re: [PATCH v4 2/3] arm64: dts: ti: Add k3-am62l3-beaglebadge

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 5 potential issue(s) to consider:
- [High] Unmanaged Board Control GPIOs (Missing GPIO Hogs / Regulators) for `BOOST_5V_ENA` and `USB_HUB_RST`.
- [High] Driver/DTB Interface Violation: `microchip,spi-present-mask` length mismatch.
- [High] Missing `bootph-all` property on referenced pinctrl nodes will cause U-Boot SPL probe failures.
- [Medium] Misplaced Consumer Pinctrl Configurations on the `&gpio0` provider node.
- [Low] Deprecated `gpio` property used instead of `gpios` in `regulator-fixed` nodes.

arm64: dts: ti: Add k3-am62l3-beaglebadge

This patch introduces the device tree for the BeagleBoard.org BeagleBadge,
a compact single board computer based on the TI AM62L3 SoC. It provides
the initial hardware description including regulators, GPIOs, pinmux
configurations, and basic peripherals.

This isn't a bug, but could the gpios property be used here instead of the
deprecated gpio property? The wlan_en node later in this file correctly uses
the plural form.

Could this also be updated to use the gpios property?

Because the gpio0 node later in the file includes the bootph-all property and
references this node, does this node also need bootph-all? Without it,
U-Boot's fdtgrep might strip this node, leaving a dangling phandle and
causing probe failures in SPL.

Does this node also need the bootph-all property? The sensor_3v3 regulator
node uses this pinctrl configuration and has bootph-all.

Same question here regarding the bootph-all property since this is referenced
by the gpio0 node.

Does this node also need bootph-all to match the gpio0 node?

Also, I noticed that GPIO0_15 (BOOST_5V_ENA) and GPIO0_43 (USB_HUB_RST)
are configured as PIN_OUTPUT here. Because configuring PIN_OUTPUT in pinctrl
only sets the pad multiplexing and does not actively drive a logic level on
the GPIO controller, will these pins remain floating?

Should there be a gpio-hog or consumer regulator node to manage the direction
and logic level for these control pins?

Is it expected to place the pinctrl configurations for consumer devices
(usr_button_pins_default and lora_control_pins_default) on the gpio0
provider node?

This causes the pins to be claimed when the GPIO controller probes. Could
these be moved to the respective consumer device nodes instead?

Will this cause a probe failure in the pinctrl-mcp23s08_spi driver?

The driver uses device_property_read_u32() to parse the
microchip,spi-present-mask property. Because the property is defined here
as an 8-bit value, the property read API will see a length mismatch and
might return -EOVERFLOW.

Could this be specified as a standard 32-bit cell (i.e., <0x01>)?
