[PATCH v2 0/8] watchdog: loongson1: Add Loongson-7A watchdog support

[PATCH v2 0/8] watchdog: loongson1: Add Loongson-7A watchdog support

[Rong Zhang]

The Loongson-7A has a watchdog compatible with the one on Loongson
2K0300. It uses an internal 50MHz clock source of the PCH, which is also
shared among other miscellaneous peripherals in the PCH.

Add a 50MHz fixed-clock node with label "pch_misc_clk" to represent the
miscellaneous clock, and migrate existing miscellaneous peripherals
(namely, ls7a_uart*) to use it rather than clock-frequency.

With that, add "loongson,ls7a-wdt" compatible to dt-bindings and the
corresponding watchdog node to ls7a-pch.dtsi. Afterward, enable
LOONGSON1_WDT in defconfig to make it work by default.

Tested on Loongson-LS3A4000-7A1000-NUC-SE and Lenovo KaiTian M530Z.

Since the series modifies ls7a-pch.dtsi here and there, it also fixes
the weird semi-dec-semi-hex style in ranges and reg properties and add
the missing #address-cells = <0> properties to interrupt-controller
nodes.

Changes in v2:
- Add a fixed-clock node to represent the clock source for miscellaneous
  peripherals instead of introducing a new clock-frequency node (thanks
  Guenter Roeck, Conor Dooley)
- With the above change, "loongson,ls7a-wdt" is now compatible with
  "loongson,ls2k0300-wdt" (ditto)
- Replace pre-existing clock-frequency nodes by utilizing the new
  fixed-clock node (thanks Conor Dooley)
  - Suppress warnings in lefi_fixup_fdt_serial() when the UART has a
    clocks node
- Fix weird semi-dec-semi-hex style addresses and ranges (ditto)
  - Also fix pre-existing ones, as their context (clock-frequency) is
    touched by the series due to the previous change
- Rephrase commit messages (ditto)
- Add missing #address-cells to interrupt controllers, as its absence
  causes a flood of warning when verifying my changes
- Link to v1: https://patch.msgid.link/20261110-mips-ls7a-wdt-v1-0-968bb85122e6@oss.cipunited.com

[PATCH v2 2/8] MIPS: Loongson64: env: Don't warn if UART has clocks node when fixing up FDT

[Rong Zhang]

A UART with clocks node cannot (and doesn't need to) be fixed up.

The fixup is solely for the case in which the UART use a dedicated clock
source on board (say, a crystal oscillator). IOW, when a UART has a
valid clocks node, it should use an internal clock source that is either
nonconfigurable by the board manufacturer, or retrievable by software.

When fixing up FDT using UART information from LEFI, don't warn if a
UART has a valid clocks node.

Currently no Loongson64 platform has such UART nodes, so this is not a
fix. Later changes will convert some nodes and depends on this.

[PATCH v2 4/8] MIPS: Loongson64: dts: ls7a-pch: Use hex in ranges and reg properties

[Rong Zhang]

The ls7a-pch.dtsi mixes two different styles of addresses and sizes.
Some use a all-hex style while some use a semi-dec-semi-hex style.

The latter style is confusing and hard to read, so convent all ranges
and reg properties into the former style.

The following changes will replace ls7a_uart*'s clock-frequency
properties. There are reg properties with the unfavoured style around
the context, so I decided that this series should fix them as well as
other properties for address and size.

[PATCH v2 6/8] MIPS: Loongson64: dts: ls7a-pch: Bind UART nodes to miscellaneous clock

[Rong Zhang]

The Loongson-7A's UART controllers are driven by an internal 50MHz clock
source called miscellaneous clock. The clock is nonconfigurable for
board manufacturer and software.

Therefore, the LS7A UART nodes don't need to be fixed up by
lefi_fixup_fdt_serial(), and can safely use clocks nodes rather than
clock-frequency ones.

[PATCH v2 8/8] MIPS: loongson3_defconfig: Enable LOONGSON1_WDT by default

[Rong Zhang]

The Loongson-7A has a watchdog compatible with the one on Loongson
2K0300. With the relevant node added to ls7a-pch.dtsi, enable
LOONGSON1_WDT in defconfig to make it work by default.

This basically mirrors commit 5e73ad3ffceb ("MIPS: Loongson1: Add
watchdog support for Loongson1 board") except that the driver is built
as a module, since some LOONGSON64 platforms are not LS7A-based.

The defconfig file is outdated, so this also refreshes it with
savedefconfig.

Tested on Loongson-LS3A4000-7A1000-NUC-SE and Lenovo KaiTian M530Z.
