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 Signed-off-by: Rahul Bedarkar --- .../bindings/mips/img/pistachio-marduk.txt | 10 ++ MAINTAINERS | 6 + arch/mips/boot/dts/img/Makefile | 9 ++ arch/mips/boot/dts/img/pistachio_marduk.dts | 163 +++++++++++++++++++++ 4 files changed, 188 insertions(+) create mode 100644 Documentation/devicetree/bindings/mips/img/pistachio-marduk.txt create mode 100644 arch/mips/boot/dts/img/Makefile create mode 100644 arch/mips/boot/dts/img/pistachio_marduk.dts diff --git a/Documentation/devicetree/bindings/mips/img/pistachio-marduk.txt b/Documentation/devicetree/bindings/mips/img/pistachio-marduk.txt new file mode 100644 index 0000000..2d5126d --- /dev/null +++ b/Documentation/devicetree/bindings/mips/img/pistachio-marduk.txt @@ -0,0 +1,10 @@ +Imagination Technologies' Pistachio SoC based Marduk Board +========================================================== + +Compatible string must be "img,pistachio-marduk", "img,pistachio" + +Hardware and other related documentation is available at +https://docs.creatordev.io/ci40/ + +It is also known as Creator Ci40.
