This series adds support for the ALIENTEK QuarkPi-CA2, an RK3588S based
single board computer. The binding patch documents the board, the DTS
patch describes the hardware.
The DTS was rebuilt from scratch against the vendor 5.10 BSP device tree
and then translated to current mainline bindings, so that every node and
property has a vendor-side or schematic origin instead of being carried
over from the earlier revisions.
Changes in v11:
- Trim the commit message down to the board description and the list of
supported peripherals.
- Drop the Assisted-by tag.
- Note on the Reviewed-by line which nodes were reviewed.
- Sort the properties in aliases alphabetically.
- Sort the nodes without unit addresses alphabetically, everywhere.
- Drop the deprecated regulator-suspend-microvolt properties.
- Sort the phandle references alphabetically.
- Keep a single root node and merge the extra root nodes and the &{/}
block into it.
- Link to v10: https://patch.msgid.link/20261023-quarkpi-ca2-v10-0-9db904194e03@163.com
Changes in v10:
- Add the Acked-by tag from Conor Dooley, which I missed.
- Add the missing domain-supply for the GPU and NPU power domains. Without
it the power domain driver falls back to a dummy regulator for both.
- Enable the three NPU IOMMUs the enabled NPU cores reference. Without them
opening /dev/accel/accel0 fails with -ENODEV.
- Link to v9: https://patch.msgid.link/20261021-quarkpi-ca2-v9-0-b75006b22bc5@163.com
Testing: boots from microSD with this series on a v7.3 kernel, and the
on-board hardware (microSD, eMMC, HDMI, USB-C DP altmode, USB 3.0 and
USB 2.0, PCIe Wi-Fi, Bluetooth, GbE, ES8388 playback, PWM fan) works;
"make CHECK_DTBS=y" is clean. The NPU works on this revision (all three
cores detected, IOMMUs attached, /dev/accel/accel0 opens, MNIST classifier
95.00% correct on 200 images), and so do the H.264, HEVC, VP8 and AV1
decode paths.
Note: there is no fiq_debugger node, so the debug console is ttyS2 and
console=ttyS2,1500000 has to be added to the bootargs manually. Capture
from the headset microphone does not work with the in-tree es8328 driver;
that is fixed by a separate ASoC patch series (sound/soc/codecs/es8328.c)
and does not affect playback.
Changes in v9:
- SD card: drop enable-active-high again, the power switch of the card
slot (vcc_3v3_sd_s0) is active low. The v8 conclusion that it was missing
came from a test run with the wrong DTB loaded; with the property present the
regulator core drives the enable pin high and the card's rail stays off.
- Audio: the I2S0 MCLK pinmux moved from the I2S controller node to the codec node.
Link to v8: https://lore.kernel.org/all/20261007-quarkpi-ca2-v8-0-b83192bed07b@163.com/
Changes in v8:
- SD card: add the missing enable-active-high to the SD card power switch
(vcc_3v3_sd_s0). Without it of_gpio_quirk_polarity() forces
OF_GPIO_ACTIVE_LOW onto the GPIO descriptor, so enabling the regulator
switched the rail off instead of on and the card lost its power.
Reported by the sashiko review; verified on hardware, the board now
boots from an SD card:
https://lore.kernel.org/all/sashiko-outbox-162297@kernel.org/
- SPI0: describe the two chip selects as GPIOs (cs-gpios) instead of
muxing the dedicated SPI0_CS0_M3 / SPI0_CS1_M3 pins, so that both chip
select lines stay usable from the 40-pin header. Verified on hardware:
both lines are claimed by the SPI core.
- Link to v7:
https://lore.kernel.org/all/20261007-quarkpi-ca2-v7-v7-0-a84c6d5d6ef6@163.com/
Please review.

computer. The board comes in 4, 8 and 16 GiB LPDDR4X variants with
32 GB, 64 GB or 128 GB of eMMC; this was tested on the 16 GiB/128 GB
one.
Supported peripherals:
- 2x LPDDR4X SDRAM and eMMC, plus the microSD card slot
- RK806-1 PMIC with the full regulator tree
- HDMI output up to 4K60, through hdptxphy0 and VOP2
- Gigabit Ethernet with the YT8531 RGMII PHY on MDIO1
- four USB Type-A ports (1x USB 3.0, 3x USB 2.0)
- USB Type-C port with USB 3.0 and DP output, described through the
USBDP PHY and DP0, with role switch and DP altmode
- 3.5 mm headset jack (headphones + microphone) with the ES8388
codec, the headphone amplifier and jack detection
- three function keys (volume down, volume up and PWR_ON from the
PMIC) and the headset hook button
- IR receiver, 4-pin PWM fan connector and a work LED
- 3-wire debug UART (UART2)
- 40-pin expansion header with UART5, I2C3, I2C5, SPI0 and PWM14
- two 26-pin MIPI DSI and three 22-pin MIPI CSI connectors, with the
connector I2C buses enabled (i2c4, i2c7); panels and cameras are
described by overlays
- M.2 E-key socket for a WiFi/BT module, with the PCIe 2.0 x1 link
enabled (pcie2x1l2, combphy0_ps)
- Mali GPU and the three NPU cores

[Severity: Low]
As reported by Heiko Stuebner on v10 [1], should all nodes without unit
addresses and phandle references in arch/arm64/boot/dts/rockchip/rk3588s-quarkpi-ca2.dts
be sorted in natural alpha-numeric order, with blank lines separating
sibling nodes?
Specifically:
- Under &spi2/pmic@0/regulators, dcdc-reg2 and dcdc-reg4 are placed before
dcdc-reg1, and dcdc-reg10 is placed before dcdc-reg3 instead of natural
alpha-numeric order dcdc-reg1 through dcdc-reg10.
- Phandle reference &pwm14 is placed before &pwm7 instead of &pwm7 before
&pwm14.
- Inside analog-sound, simple-audio-card,cpu is placed before
simple-audio-card,codec.
- Blank lines are missing between aliases and analog-sound, after
simple-audio-card,routing in analog-sound, between chosen and hdmi0-con,
between headset-keys and ir-receiver, and between hp-con and hp-det,
headphone and ir, and pcie and sdmmc in &pinctrl.
