[PATCH 0/4] watchdog: loongson1: Add Loongson-7A watchdog support

[PATCH 0/4] watchdog: loongson1: Add Loongson-7A watchdog support

[Rong Zhang]

The Loongson-7A watchdog is similar to Loongson 2K0300, except that it
has no clock controller.

Add "loongson,ls7a-wdt" compatible as well as a conditionally required
field clock-frequency. The driver will retrieve clock frequency from OF
to make it work.

With these, add a watchdog node to the LS7A PCH dtsi to wire it up, and
enable LOONGSON1_WDT in defconfig to make it work by default.

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

Wouldn't it be much easier to just create a fixed rate clock and use it
(as suggested by Sashiko in the devicetree patch) ?

Makes sense. I will take that approach (and fix other concerns found by
Sashiko) when I resubmit this.

[PATCH 3/4] MIPS: Loongson64: Add watchdog node for LS7A PCH

[Rong Zhang]

The Loongson-7A has a watchdog. With proper support added to the
loongson1_wdt driver, wire it up by adding a watchdog node to
ls7a-pch.dtsi.

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

[PATCH 4/4] MIPS: loongson3_defconfig: Enable LOONGSON1_WDT by default

[Rong Zhang]

The Loongson-7A has a watchdog. With proper support added to the
loongson1_wdt driver and a 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 also refreshed.

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