ARM: dts: sunxi: Fix the LED node names

2021-01-18T09:13:16+00:00

According to the LED bindings, the LED node names are supposed to be led
plus an optional suffix. Let's fix our users to use that new scheme.

ARM: dts: sunxi: Add mdio bus sub-node to GMAC

2019-08-23T07:14:48+00:00

The DWMAC binding never supported having the Ethernet PHY node as a
direct child to the controller, nor did it support the "phy" property
as a way to specify which Ethernet PHY to use. What seemed to work
was simply the implementation ignoring the "phy" property and instead
probing all addresses on the MDIO bus and using the first available
one.

The recent switch from "phy" to "phy-handle" breaks the assumptions
of the implementation, and does not match what the binding requires.
The binding requires that if an MDIO bus is described, it shall be
a sub-node with the "snps,dwmac-mdio" compatible string.

Add a device node for the MDIO bus, and move the Ethernet PHY node
under it. Also fix up the #address-cells and #size-cells properties
where needed.

ARM: dts: sunxi: Switch from phy to phy-handle

2019-07-22T07:41:10+00:00

The phy device tree property has been deprecated in favor of phy-handle,
let's replace it.

ARM: dts: sunxi: Remove pinctrl groups setting bias

2019-04-04T07:25:15+00:00

So far we've enabled pull-up and pull-down resistors on GPIOs using a
pinctrl node. Now that the GPIO binding allows for a flag to declare this,
let's switch to it.

This brings us closer to removing all the GPIO pinctrl nodes, which will in
turn allow us to switch the pinctrl strict mode on.

ARM: sunxi: Fix the USB PHY ID detect GPIO properties

2019-03-25T20:26:27+00:00

While the USB PHY Device Tree mandates that the name of the ID detect pin
should be usb0_id_det-gpios, a significant number of device tree use
usb0_id_det-gpio instead.

This was functional because the GPIO framework falls back to the gpio
suffix that is legacy, but we should fix this.

ARM: dts: sun7i: Provide default muxing for relevant controllers

2018-11-28T14:14:15+00:00

The I2C and MMC controllers have only one muxing option in the SoC. In such a
case, we can just move the muxing into the DTSI, and remove it from
the DTS.

ARM: dts: sun7i: Remove underscores from nodes names

2018-11-28T14:14:14+00:00

Some GPIO pinctrl nodes cannot be easily removed, because they would also
change the pin configuration, for example to add a pull resistor or change
the current delivered by the pin.

Those nodes still have underscores and unit-addresses in their node names
in our DTs, so adjust their name to remove the warnings. Use that occasion
to also fix some poorly chosen node-names.

ARM: dts: sun7i: Change pinctrl nodes to avoid warning

2018-11-28T14:14:13+00:00

All our pinctrl nodes were using a node name convention with a unit-address
to differentiate the different muxing options. However, since those nodes
didn't have a reg property, they were generating warnings in DTC.

In order to accomodate for this, convert the old nodes to the syntax we've
been using for the new SoCs, including removing the letter suffix of the
node labels to the bank of those pins to make things more readable.

ARM: dts: sun7i: Remove gpio-keys warnings

2018-11-28T14:14:13+00:00

Some gpio-keys definitions in our DTs were having buttons defined with a
unit-address and that would generate a DTC warning.

Change the buttons node names to remove the warnings.

ARM: dts: sun7i: Remove all useless pinctrl nodes

2018-11-28T14:14:12+00:00

The gpio pinctrl nodes are redundant and as such useless most of the times.
Since they will also generate warnings in DTC, we can simply remove most of
them.
