[PATCH v6 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/e9e95848336fda0e4b5acb37f2fe64a0

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

Changelog since v5:
DTS
- Fixed aliases/chosen nodes
- Sort Makefile items alphabetically
- Use dual license: GPL-2.0-only or MIT

Re: [PATCH v6 2/3] arm64: dts: ti: Add k3-am62l3-beaglebadge

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [High] Driver-Binding Mismatch: The `mcp23s18` GPIO expander probe will fail due to property size mismatch.

Author: Judith Mendez <jm@ti.com>

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

This commit adds the device tree for the BeagleBoard.org BeagleBadge, based on
the Texas Instruments AM62L3 SoC. It includes configurations for memory, GPIO
keys, LEDs, regulators, MMC, USB, PWM, I2C, SPI, and other peripherals.

[Severity: High]
Does this 8-bit property cause the driver probe to fail?

Looking at drivers/pinctrl/pinctrl-mcp23s08_spi.c, the driver attempts to read
this property using device_property_read_u32(). Because it expects at least
4 bytes of data, of_find_property_value_of_size() will evaluate the length
as insufficient and return -EOVERFLOW.

This would cause the driver probe to fail, leaving the MCP23S18 GPIO expander
and connected devices non-functional. Should this property be defined as a
standard 32-bit value to match the driver's expectations?
