-Subject: MIPS: DTS: img: add device tree for Marduk board
-
-Add support for Imagination Technologies' Marduk board which is based
-on Pistachio SoC. It is also known as Creator Ci40. Marduk is legacy
-name and will be there for decades.
-
-Documentation for this board can be found on
-https://docs.creatordev.io/ci40/
-
-This patch adds initial support for board with following peripherals:
-
-* PWM based heartbeat LED
-* GPIO based buttons
-* SPI NOR flash on SPI1
-* UART0 and UART1
-* SD card
-* Ethernet
-* USB
-* PWM
-* ADC
-* I2C
-
-(apply from https://patchwork.linux-mips.org/project/linux-mips/list/?submitter=7165)
