[PATCH v2 0/3] arm64: dts/bindings: Add support for BeagleBadge

[PATCH v2 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/d37fdb1f8113dc4d3d21479a61542106

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

Changelog:
Binding:
- Update compatible to: beagle,am62l3-beaglebadge
DTS:
- Add thermal zones
- Move pinmux definitions from consumer nodes to  base controller nodes
- Define GPIOs for each of use: BOOST_5V_ENA, USB_HUB_RST, MIKROBUS_RST
- Add Andrew's sign-off tag
Defconfig:
- Add defconfig patch which enables drivers as modules for beaglebadge

Patch series depends on:
- "pinctrl: mcp23s08: Initialize mcp->dev and mcp->addr before regmap init"
- Link: https://lore.kernel.org/all/20260508214324.1040460-1-jm@ti.com

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

BeagleBoard.org BeagleBadge is a compact, affordable open source hardware
single board computer based on the Texas Instruments AM62L3 SoC. Expansion
is provided over open standards based headers including QWIIC and GPIO
interfaces.

Is 255 nanoseconds the correct PWM period here?

This translates to a frequency of ~3.9 MHz, which is far too fast for LED
brightness control and provides virtually no duty cycle resolution.

Was the max-brightness value (255) incorrectly copied into the PWM period cell?

Should this load switch be connected to &vcc_3v3_main instead of &vsys_out?

Since it is a load switch, its output voltage matches its input voltage.
Connecting its vin-supply to &vsys_out (4.4V) contradicts the node's
regulator-max-microvolt = <3300000> configuration, causing it to pass
4.4V to a 3.3V rail.

Does this pin need to be configured for muxmode 7?

The comments and the reset-gpios property of the mcp23s18 node expect this pin
to act as GPIO0_25. On AM62Lx SoCs, the GPIO function is located at muxmode 7.

With muxmode 4, the pad won't be connected to the GPIO controller, and the
GPIO expander will remain in reset.

This isn't a bug, but there's a typo (FUEL_GUAGE_BATLOW) in the line name.

Are these #address-cells and #size-cells properties needed here?

Since the sdhci2 node contains no child nodes, this will trigger an
avoid_unnecessary_addr_size dtc warning.

Should microchip,spi-present-mask be formatted as /bits/ 8 <0x01>?

The microchip,mcp23s08.yaml device tree binding schema requires this property
to be a uint8, so keeping it as a 32-bit cell will trigger a dt_binding_check
validation error.

commit 6f7a4afa4cd800dc21fa4233eabb09b5e3390bc1

arm64: defconfig: Enable drivers for BeagleBadge

This commit enables several drivers as modules or built-in for the
BeagleBadge device. The enabled drivers include LED PWM Multicolor, MCP SPI
IO Expander, Seven Segment display GPIO, and Temperature Sensor.

This isn't a bug, but was this defconfig updated using make savedefconfig?

Manual insertions can disrupt the canonical Kconfig parsing order. Based on
the definitions in drivers/hwmon/Kconfig, SENSORS_SHT4x is defined after
SENSORS_SL28CPLD and before SENSORS_AMC6821, so its proper canonical
placement would be between those two entries.

Similarly, should CONFIG_LEDS_PWM_MULTICOLOR precede CONFIG_LEDS_QCOM_LPG
to match the order in drivers/leds/rgb/Kconfig?
