[PATCH v8 5/5] arm: dts: add new device nodes to NPCM750 device tree EVB

From: Tomer Maimon
Date: Tue Sep 29 2020 - 09:19:05 EST


Add the following new device nodes to
NPCM750 evolution board device tree:

- NPCM7xx Pin controller and GPIO
- NPCM7xx PWM and FAN.
- NPCM7xx EHCI USB.
- NPCM7xx KCS.
- NPCM Reset.
- NPCM Peripheral SPI.
- NPCM FIU SPI.
- NPCM HWRNG.
- NPCM I2C.
- STMicro STMMAC.
