maoxiaochuan 55a9dbec94 dt-bindings: clock: loongson2: Add Loongson-2K0300 compatible 
Document the clock controller shipped in Loongson-2K0300 SoC, which
generates various clock signals for SoC peripherals. Differing from
previous generations of SoCs, LS2K0300 requires a 120MHz external clock
input.

Binbin Zhou 64e7ec3ead dt-bindings: watchdog: loongson,ls1x-wdt: Add ls2k0300-wdt compatible 
Add "loongson,ls2k0300-wdt" compatible to the dt-schema document, which
is similar to Loongson-1 watchdog, but with differences in some register
offsets and bit definitions.

Yao Zi 1e9ca25a84 dt-bindings: gpio: loongson: Document GPIO controller of LS2K0300 SoC 
Loongson-2K0300 ships a GPIO controller whose input/output control logic
is similar to previous generation of SoCs. Additionally, it acts as an
interrupt-controller supporting both level and edge interrupts and has a
distinct reset signal.

Describe its compatible in devicetree. We enlarge the maximum value of
ngpios to 128, since the controller technically supports at most 128
pins, although only 106 are routed out of the package. Properties for
interrupt-controllers and resets are introduced and limited as LS2K0300
only.
