[PATCH v3 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 v2:
DTS:
- PWM period: 255ns -> 10000000ns
- vdd_3v3 vin-supply: vsys_out -> vcc_3v3_main
- MCP23S18 reset muxmode: 4 -> 7
- Typo: FUEL_GUAGE_BATLOW -> FUEL_GAUGE_BATLOW
- sdhci2: Remove  #address-cells & #size-cells
Defconfig:
- Move config options as per make savedefconfig

V2

V1
Link: https://lore.kernel.org/all/20260501233148.4180391-1-jm@ti.com/

Patch series depends on:

Drop, it's just vendor website.

Missing blank line. Please follow standard patch format.

Maybe that was supposed to be tag?

Best regards,

Re: [PATCH v3 2/3] arm64: dts: ti: Add k3-am62l3-beaglebadge

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 3 potential issue(s) to consider:
- [High] The `microchip,spi-present-mask` property is specified as an 8-bit value, which will cause the mcp23s18 driver probe to fail.
- [High] Missing `bootph-all` property on `&wkup_i2c0` and its PMIC child node `tps65214`.
- [Low] Unnecessary inclusion of DT binding header files.

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

This commit adds the device tree for the BeagleBoard.org BeagleBadge,
a compact single board computer based on the TI AM62L3 SoC. It provides
initial support including GPIOs, LEDs, regulators, and other peripherals.

Are these last two includes necessary?

It doesn't look like there are any DP83867 Ethernet PHY nodes in this device
tree to use the networking macros.

Also, the thermal zone trip point uses a raw string literal for the type
rather than the standard macros defined in thermal.h.

Will U-Boot SPL drop the I2C bus and PMIC from its device tree, failing to
configure essential SoC voltages like VDD_CORE, VDD_1V8, and VDD_LPDDR4?

While the associated pinmux group wkup_i2c0_pins_default correctly specifies
bootph-all, both the wkup_i2c0 controller node and the PMIC child node do not.

Could this prevent the board from booting?

Will the mcp23s18 driver probe fail here because of the 8-bit mask value?

The driver in drivers/pinctrl/pinctrl-mcp23s08_spi.c attempts to read this
using device_property_read_u32(), which expects a property of at least 4 bytes.

Reading a 1-byte property will cause the underlying
of_property_read_variable_u32_array() to return -EOVERFLOW, which could
completely disable the GPIO expander and its dependent peripherals.
