[PATCH v1 00/15] Maintenance updates for Protonic Holland boards

[Oleksij Rempel]

This patchset consists of several updates that address issues on
Protonic Holland's supported i.MX6-based devices, with a particular
focus on the USB subsystem configuration, thermal zones, and the naming
of GPIO keys. Some of these changes include the activation of USB over-
current detection on certain ports, the disabling of unused USB PHY
nodes, fixing USB-related warnings, adding trip points to thermal zones
on several devices, and renaming the 'power' key to meet the necessary
conventions.

[PATCH v1 01/15] ARM: dts: imx6qdl: vicut1: The sgtl5000 uses i2s not ac97

[Oleksij Rempel]

From: Robin van der Gracht <robin@protonic.nl>

According to Documentation/devicetree/bindings/sound/fsl,ssi.txt
'fsl,mode' should be specified for AC97 mode only.

The 'fsl,ssi' documentation doesn't say anything about specifying
'sound-dai-cells' so we'll remove that as well.

[PATCH v1 02/15] ARM: dts: imx6dl: prtvt7: Adjust default backlight brightness to 65

[Oleksij Rempel]

From: Robin van der Gracht <robin@protonic.nl>

This commit changes the default brightness level of the backlight on the
prtvt7 device from 20 to 65, roughly equivalent to 75% of the maximum
brightness level defined in the "brightness-levels" property.

The adjustment provides a more optimal default brightness for the
device, improving the overall user experience.

[PATCH v1 05/15] ARM: dts: imx6dl: lanmcu: Disable unused USB PHY nodes

[Oleksij Rempel]

In the imx6dl-lanmcu system, the usbh2 and usbh3 interfaces are not in
use. However, the related USB PHY nodes (usbphynop1 and usbphynop2) are
enabled by default in the imx6qdl.dtsi file, which can lead to confusion
and potential resource mismanagement.

This commit explicitly disables these unused USB PHY nodes in the
imx6dl-lanmcu device tree, aligning the configuration more accurately
with the actual hardware setup.

[PATCH v1 06/15] ARM: dts: imx6dl: lanmcu: Configure over-current polarity for USB OTG node

[Oleksij Rempel]

This commit adds the 'over-current-active-low' flag to the USB OTG node
in the imx6dl-lanmcu device tree. This flag is necessary because the
hardware signals over-current conditions by pulling the line low.
Without this flag, the kernel could misinterpret an over-current
condition, leading to unexpected behavior.

[PATCH v1 07/15] ARM: dts: imx6dl: Add trip points to thermal zones on several devices

[Oleksij Rempel]

Kernel v6.3-rc1 prints errors due to missing trip points in thermal
zones. These errors indicate a lack of critical temperature threshold
settings, causing warnings at boot. To silence these errors, this patch
introduces trip points into the thermal zones of several imx6dl based
devices.

The following devices are updated:
- plym2m
- prtvt7
- victgo
- vicut1

These devices are automotive grade and expected to operate up to 105C.
An exception is the plym2m, an industrial grade device, which is
certified to work up to 85C.

The added trip points act as alert thresholds but do not trigger any
actions except warnings. This behavior is by design, as these devices
should maintain their performance until the end, without any thermal
throttling.

[PATCH v1 08/15] ARM: dts: imx6dl: vicut1: Address USB related warnings

[Oleksij Rempel]

This patch addresses several USB-related warnings in the device tree for
the imx6dl vicut1 system. Specifically, it disables the unused
usbphynop1 and usbphynop2 USB PHYs, and disables unsupported
over-current detection. This action mitigates the following kernel
warnings:
usb_phy_generic usbphynop1: dummy supplies not allowed for exclusive requests
usb_phy_generic usbphynop2: dummy supplies not allowed for exclusive requests
imx_usb 2184200.usb: No over-current polarity defined

[PATCH v1 11/15] ARM: dts: imx6qp: prtwd3: Enable USB over current detection on USB OTG port

[Oleksij Rempel]

The imx6qp-prtwd3 board supports USB over current detection on the USB
OTG port, however, it was previously disabled in the device tree. This
commit enables the over current detection by changing the device tree
setting from 'disable-over-current' to 'over-current-active-low'. This
could potentially protect the USB port from damage due to over current
situations.

[PATCH v1 12/15] ARM: dts: imx6ul: prti6g: fix USB over-current detection on USB OTG port

[Oleksij Rempel]

USB over-current detection is supported on this board. So, activate it
and fixes the following kernel warnings:
 imx_usb 2184200.usb: No over current polarity defined

[PATCH v1 14/15] ARM: dts: imx6dl: prtrvt, prtvt7, prti6q, prtwd2: fix USB related warnings

[Oleksij Rempel]

Fix USB-related warnings in prtrvt, prtvt7, prti6q and prtwd2 device trees
by disabling unused usbphynop1 and usbphynop2 USB PHYs and providing proper
configuration for the over-current detection. This fixes the following
warnings with the current kernel:
 usb_phy_generic usbphynop1: dummy supplies not allowed for exclusive requests
 usb_phy_generic usbphynop2: dummy supplies not allowed for exclusive requests
 imx_usb 2184200.usb: No over current polarity defined

By the way, fix over-current detection on usbotg port for prtvt7, prti6q
and prtwd2 boards. Only prtrvt do not have OC on USB OTG port.

[PATCH v1 15/15] ARM: dts: imx6qdl: vicut1: rename power to power-button

[Oleksij Rempel]

In order to address the warnings about the naming convention for keys,
this commit renames the 'power' key to 'power-button' in the vicut1-12inch
device tree source file. The warning in question is as follows:
arch/arm/boot/dts/imx6q-vicut1.dtb: gpio-keys: 'power' does not match
any of the regexes:
'^(button|event|key|switch|(button|event|key|switch)-[a-z0-9-]+|[a-z0-9-]+-(button|event|key|switch))$',
'pinctrl-[0-9]+'

The referenced warning originates from the following schema:
Documentation/devicetree/bindings/input/gpio-keys.yaml
