mips: dts: ralink: mt7621: define each reset as an item

2023-10-06T08:12:32+00:00

Each item of the resets property should define a reset. Split the item with
two resets on the ethernet node into two separate items.

Sort the items of the clocks property to the same line as a trivial change.

mips: dts: ingenic: Remove unneeded probe-type properties

2023-10-06T08:12:10+00:00

The "probe-type" property was only needed when used with the
(long obsolete) "direct-mapped" compatible value.

MIPS: DTS: CI20: Raise VDDCORE voltage to 1.125 volts

2023-06-23T13:00:18+00:00

Commit 08384e80a70f ("MIPS: DTS: CI20: Fix ACT8600 regulator node
names") caused the VDDCORE power supply (regulated by the ACT8600's
DCDC1 output) to drop from a voltage of 1.2V configured by the
bootloader, to the 1.1V set in the Device Tree.

According to the documentation, the VDDCORE supply should be between
0.99V and 1.21V; both values are therefore within the supported range.

However, VDDCORE being 1.1V results in the CI20 being very unstable,
with corrupted memory, failures to boot, or reboots at random. The
reason might be succint drops of the voltage below the minimum required.

Raising the minimum voltage to 1.125 volts seems to be enough to address
this issue, while still keeping a relatively low core voltage which
helps for power consumption and thermals.

mips: dts: ralink: mt7628a: Unify pinctrl-single pin group nodes

2023-06-09T09:34:45+00:00

We want to unify the pinctrl-single pin group nodes to use naming "pins".
Otherwise non-standad pin group names will add make dtbs checks errors
when the pinctrl-single yaml binding gets merged.

mips: dts: ralink: Add support for TP-Link HC220 G5 v1 board

2023-06-09T07:56:09+00:00

This WiFi AP is based on a MT7621 SoC with 128MiB RAM, 128MiB NAND,
a MT7603 2.4GHz WiFi and a MT7613 5GHz WiFi chips integrated on the board,
connected to the main SoC over PCIe.

The device uses NMBM over NAND, which is not currently supported in the
mainline, so NAND node is skipped in this revision.

MIPS: DTS: CI20: Enable support for WiFi / Bluetooth

2023-06-09T07:55:38+00:00

Wire the WiFi/Bluetooth chip properly in the Device Tree.

- Provide it with the correct regulators and clocks;
- Change the MMC I/O bus to 1.8V which seems to be enough;
- Change the MMC I/O bus frequency to 25 MHz as 50 MHz causes errors;
- Fix the Bluetooth powerdown GPIO being inverted and add reset GPIO;
- Convert host-wakeup-gpios to IRQ.

With these changes, the WiFi works properly with the latest firmware
provided by linux-firmware. The Bluetooth does not work very well here,
as I cannot get my wireless keyboard to pair; but it does detect it, and
it does see the key presses when I type the pairing code.
