[PATCH v5 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.

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 v4:
- Canonical URL fixed
- Switch gpio -> gpios in voltage regulator nodes
- Regulator-always-on removed in sensor_3v3
- Add bootph-all on pinmux nodes
- Fix gpio-line-names formatting
- Nodes: sdhci2, wlan_en regulator, & pinmux removed
- USB aliases removed
- Pickup Conor's review tag

Re: [PATCH v5 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 property `microchip,spi-present-mask` is incorrectly defined as an 8-bit integer, which will cause a probe failure.
- [Medium] Missing `serial0` alias and namespace collision with `gpio2`.
- [Low] Alphabetical sorting violation in the TI device tree Makefile.

Author: Judith Mendez <jm@ti.com>

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

This commit adds the device tree for the BeagleBoard.org BeagleBadge,
which is based on the AM62L3 SoC. It includes configurations for GPIO keys,
LEDs, PWM beepers, regulators, PMIC, and several I2C and SPI peripherals.

[Severity: Low]
This isn't a bug, but should this be sorted alphabetically? The other entries
in this Makefile usually follow alphabetical order, so k3-am62l3-beaglebadge.dtb
would normally be placed before k3-am62l3-evm.dtb.

[Severity: Medium]
Will aliasing wkup_gpio0 to gpio2 cause an enumeration collision? 

The base k3-am62l-main.dtsi already defines a physical gpio2 controller, so
using ID 2 for wkup_gpio0 might conflict if the real gpio2 is ever enabled.

Also, since stdout-path uses uart0 and serial3 is aliased below, should there
be a serial0 alias for uart0 to ensure predictable /dev/ttyS* numbering?

[Severity: High]
Can this cause a probe failure?

The mcp23s08 pinctrl driver reads the microchip,spi-present-mask property
using device_property_read_u32().

By defining the property as an 8-bit integer, the property length in the
device tree is 1 byte instead of the 4 bytes required by
device_property_read_u32().

This could lead to of_property_read_variable_u32_array() returning
-EOVERFLOW, which would cause the mcp23s18 driver probe to fail and leave
the 7-segment displays non-functional.

arm64: defconfig: Enable drivers for BeagleBadge

[Severity: High]
This is a pre-existing issue, but does the sht4x driver lack locking for
its sysfs attributes?

The hardware monitoring subsystem guidelines state that drivers must
implement their own locking for attributes registered outside the core,
such as those in extra_groups. The sht4x driver registers heater attributes
like heater_enable via extra_groups but does not appear to provide locking.

If a write to heater_enable occurs during the usleep_range() of a
temperature read:

sht4x_read_values() {
    ret = i2c_master_send(client, cmd, SHT4X_CMD_LEN);
    ...
    usleep_range(SHT4X_MEAS_DELAY_HPM, ...);
    ...
    ret = i2c_master_recv(client, raw_data, SHT4X_RESPONSE_LENGTH);
}

Concurrent with a write to the heater:

heater_enable_store() {
    ret = i2c_master_send(data->client, &cmd, SHT4X_CMD_LEN);
    ...
    data->heating_complete = jiffies + msecs_to_jiffies(heating_time_bound);
    data->data_pending = true;
}

Could this interleave I2C traffic and cause the subsequent
i2c_master_recv() to read the wrong response or abort the measurement?
