ARM: dts: helios4: add SATA regulator supplies

2026-09-14T11:19:11+00:00

[ Upstream commit 7a90520e8c9a8f48fe6f3e741cf34d8c2b6dbc61 ] The ahci-mvebu driver and libahci_platform request three supplies on SATA controller and port nodes: - ahci-supply (controller power) - phy-supply (PHY power) - target-supply (disk power per port) Without them the regulator core prints notices at boot, e.g.: supply ahci not found, using dummy regulator supply phy not found, using dummy regulator supply target not found, using dummy regulator The SATA controller and PHY inside the Armada 388 SoC are powered by the 3.3V I/O rail; the four disk bays are powered by the 5V HDD rail. Wire the existing fixed regulators accordingly.

ARM: dts: helios4: add vcc-supply to GPIO expander

ARM: dts: helios4: add vcc-supply to EEPROM

2026-09-14T11:19:11+00:00

[ Upstream commit ef65cf08bd1aa723de2854d02fb8eb8cca273c90 ] The at24 driver requests a 'vcc' supply for the EEPROM, producing 'supply vcc not found, using dummy regulator' at boot when the property is missing. The EEPROM sits on the Helios 4 and is powered by the same always-on 3.3V rail used by other on-board I2C devices. Add vcc-supply = <®_3p3v> to silence the warning.

ARM: dts: allwinner: a10: Fix PMU interrupt

2026-09-14T11:19:02+00:00

[ Upstream commit eb7051f756460d7b951e94d9656e31ebb631ba28 ] The Performance Monitoring Unit of the Cortex-A8 cores in the Allwinner A10 SoC is connected to interrupt line 66, not 3. This is shown in the manual (where interrupt 3 is assigned to UART2, also in our .dtsi), but has also been confirmed by triggering an PMU overflow interrupt and inspecting the IRQ controller status registers (from U-Boot). Please note that "perf stat" does not use interrupts, this might explain why this evaded the initial testing.

ARM: dts: am335x-sl50: Fix audio bitclock and frame master endpoint

2026-07-24T13:48:55+00:00

[ Upstream commit 2bc564f46b00dc4f4331fc337277ff3f5fac8a4e ] The cpu_endpoint in mcasp0 specifies the TLV320AIC3106 codec as the bitclock and frame master, but the phandles point to the codec's port node (codec_port) rather than its endpoint node (codec_endpoint). audio-graph-card calls simple_util_parse_daifmt() with ep_codec set to the endpoint node (codec_endpoint). The function resolves the bitclock-master phandle and checks whether it equals ep_codec. Since codec_port is the parent of codec_endpoint, not the endpoint itself, the comparison always evaluates to false. This causes the mcasp0 CPU side to be silently configured as bitclock and frame master instead of the codec, which is the opposite of the intended configuration. Fix by pointing bitclock-master and frame-master to codec_endpoint.

ARM: dts: allwinner: sun5i-a13-utoo-p66: delete "power-gpios" property

2026-03-04T12:19:27+00:00

[ Upstream commit 0b2761eb1287bd9f62367cccf6626eb3107cef6f ] The P66's device tree includes the reference design dtsi files, which defines a node and properties for the touchpanel in the common design. The P66 dts file then overrides all the properties to match its own design, but as the touchpanel model is different, a different schema is matched. This other schema uses a different name for the GPIO. The original submission added the correct GPIO property, but did not delete the one inherited from the reference design, causing validation errors. Explicitly delete the incorrect GPIO property.
