From: Paul Cercueil
Date: Wed Dec 12 2018 - 17:17:51 EST

Add DTS nodes for the JZ4780, JZ4770 and JZ4740 devicetree files.

Signed-off-by: Paul Cercueil <paul@xxxxxxxxxxxxxxx>

Notes:
v5: New patch

v6: Fix register lengths in watchdog/pwm nodes

v7: No change

v8: - Fix wrong start address for PWM node
- Add system timer and clocksource sub-nodes
