dt-bindings: phy: imx8mq-usb: fix fsl,phy-tx-vboost-level-microvolt property

2025-06-10T11:17:11+00:00

commit 5b3a91b207c00a8d27f75ce8aaa9860844da72c8 upstream.

The ticket TKT0676370 shows the description of TX_VBOOST_LVL is wrong in
register PHY_CTRL3 bit[31:29].

  011: Corresponds to a launch amplitude of 1.12 V.
  010: Corresponds to a launch amplitude of 1.04 V.
  000: Corresponds to a launch amplitude of 0.88 V.

After updated:

  011: Corresponds to a launch amplitude of 0.844 V.
  100: Corresponds to a launch amplitude of 1.008 V.
  101: Corresponds to a launch amplitude of 1.156 V.

This will correct it accordingly.

dt-bindings: usb: cypress,hx3: Add support for all variants

2025-06-10T11:17:11+00:00

commit 1ad4b5a7de16806afc1aeaf012337e62af04e001 upstream.

The Cypress HX3 hubs use different default PID value depending
on the variant. Update compatibles list.
Becasuse all hub variants use the same driver data, allow the
dt node to have two compatibles: leftmost which matches the HW
exactly, and the second one as fallback.

dt-bindings: pwm: adi,axi-pwmgen: Fix clocks

2025-06-10T11:17:11+00:00

commit e683131e64f71e957ca77743cb3d313646157329 upstream.

Fix a shortcoming in the bindings that doesn't allow for a separate
external clock.

The AXI PWMGEN IP block has a compile option ASYNC_CLK_EN that allows
the use of an external clock for the PWM output separate from the AXI
clock that runs the peripheral.

This was missed in the original bindings and so users were writing dts
files where the one and only clock specified would be the external
clock, if there was one, incorrectly missing the separate AXI clock.

The correct bindings are that the AXI clock is always required and the
external clock is optional (must be given only when HDL compile option
ASYNC_CLK_EN=1).

dt-bindings: net: ethernet-controller: Add informative text about RGMII delays

2025-05-05T23:49:18+00:00

Device Tree and Ethernet MAC driver writers often misunderstand RGMII
delays. Rewrite the Normative section in terms of the PCB, is the PCB
adding the 2ns delay. This meaning was previous implied by the
definition, but often wrongly interpreted due to the ambiguous wording
and looking at the definition from the wrong perspective. The new
definition concentrates clearly on the hardware, and should be less
ambiguous.

Add an Informative section to the end of the binding describing in
detail what the four RGMII delays mean. This expands on just the PCB
meaning, adding in the implications for the MAC and PHY.

Additionally, when the MAC or PHY needs to add a delay, which is
software configuration, describe how Linux does this, in the hope of
reducing errors. Make it clear other users of device tree binding may
implement the software configuration in other ways while still
conforming to the binding.
